All but one of the halides will produce a precipitate with silver. So the option c is correct.

A collection of chemical compounds known as the halides include one atom of halogen joined to another element. An ionic compound may precipitate when a halide is introduced to a solution containing the ionic compound.

All of the halides, with the exception of fluoride, will precipitate when added to a solution. Fluoride ions often do not precipitate because they are too tiny to trigger the precipitation of ionic compounds. In general, halides like astatide, chloride, bromide, and iodide precipitate with ionic compounds.

The majority of solutions typically contain the highest amounts of chloride ions since they are the most prevalent. Iodide and bromide ions are present, but in lower concentrations, and they are less likely to form a precipitate that is visible.

So the option c is correct.

The Sahara Desert

Explanation:

The Sahara Desert is a physical barrier between North Africa and the rest of Africa. The Sahara is the world's largest scorching desert, covering about 3.6 million square miles (9.4 million square kilometers) from the Atlantic to the Red Sea. It is a huge desert region with high temperatures, dunes, rocky plateaus, and a rare oasis village. The Sahara essentially separates North Africa from the rest of the continent, resulting in major geological, cultural, and historical characteristics.

The physical barrier that separates North Africa from the rest of Africa is the Sahara Desert.

This vast, arid region stretches across 3.6 million square miles, making it the largest hot desert in the world. The Sahara is a formidable obstacle to travel and commerce, with harsh temperatures, shifting sands, and limited resources. For thousands of years, it has acted as a natural boundary between North Africa, which is predominantly Arab and Islamic, and sub-Saharan Africa, which is home to a diverse range of ethnic and linguistic groups.

The Sahara has shaped the history and culture of the region, influencing trade routes, migration patterns, and political alliances. Despite its challenges, however, the Sahara has also been a source of resilience and innovation for the people who live there, from the Tuareg nomads who navigate its dunes to the Sahrawi refugees who have built a new life in its barren landscape.

During this time on Mars, based on width and depth of the remaining riverbed, it is thought that the flow rate must have been enormous, as much as 100 times the flow rate of the Amazon River. The right answer is d.

There are numerous locations on Mars where large flood channels, also known as outflow channels, have been cut into the surface. The networks in the valley are substantially smaller than the canals. It is estimated that the peak outflows of the floods that cut the major outflow channels were 100 times greater than the flow rate of the Amazon River, making them really huge events.

The massive release of water from lakes appears to have caused some of the floods. Others were created by groundwater explosions. The outflow canals are more recent than the valley networks and most likely developed under conditions akin to those in use now.

Tensions between Muslims and Hindus have not subsided as much as was promised since Pakistan's separation from India.

There have been several instances of violence between the two countries despite their isolation. As Muslims, who had previously been the majority in the area, were uprooted and relocated to Pakistan as a result of the partition, there was a significant outbreak of violence in 1947.

Multiple wars between India and Pakistan between 1965 and 1971 came after that. Tensions between the two nations have risen in recent years, notably with relation to the Kashmir area.

While the separation of Pakistan from India was intended to give Muslims a safe haven, it has not been able to reduce hostilities between Hindus and Muslims.

An ecological community is a collection of populations of at least two distinct organisms that interact both directly and indirectly within a certain geographic area.

Organisms reside inside ecological communities. Numerous ecosystem characteristics and functions, such as nutrient cycling and food webs, are based on interactions between species. Depending on the evolutionary context and environmental factors that they take place in, these interactions can take on a variety of different forms.

Because of this, ecological interactions between particular individuals and entire species are usually challenging to identify and quantify and frequently rely on the scale and context of the interactions. However, there are a number of classes of interactions between organisms that are present in a wide range of habitats and ecosystems. When examining an ecological community, scientists can describe naturally occurring processes and make predictions about how changes made by humans to the environment may affect ecosystem properties and processes by using these classes of interactions as a framework.

The texture of an igneous rock that cools very quickly when it forms is typically smooth and shiny, which is known as a glassy texture.

Hence, the correct answer is smooth and shiny.

Igneous rocks are formed when magma cools and solidifies. The texture of an igneous rock is determined by the rate of cooling of the magma. If the magma cools very slowly, the resulting rock will have large crystals, while rapid cooling results in a finer-grained texture.

When magma cools extremely quickly, as in the case of volcanic eruptions, it solidifies almost instantly and may form a glassy texture.

Otherwise, if the cooling rate is slower, the rock may have a crystalline texture with visible minerals, which are often arranged in an interlocking pattern. The mineral composition and texture of an igneous rock can provide clues about its origin.

The area behind an island arc that develops a spreading center and rifts is an back-arc basin.

A specific kind of geologic basin called a back-arc basin can be found at several convergent plate borders. Back-arc basins are now all underwater landforms connected to island arcs and subduction zones, with many of them being located in the western Pacific Ocean. The majority of them are the consequence of tensional pressures brought on by the oceanic trench rollback process, in which a subduction zone shifts in the direction of the subducting plate.

Back-arc basins are found in regions where the oceanic crust subducting plate is very ancient. Asymmetric seafloor spreading distinguishes back-arc basins from typical mid-ocean ridges, however this can vary greatly even within a same basin.

Explanation:

Land reforms are frequently justified on the grounds of advancing fairness, lowering poverty, ensuring the nutrition of households with limited access to land, redressing social injustices, and preventing social unrest.

According to the many roles that land has played throughout history—as a component of production, a repository of wealth and value, a status symbol, or a source of social and political influence—the notion of land reform has changed throughout time.

If properly implemented, the need for land reform from the perspective of social justice and for a more fair allocation of fertile farmland provides a significant opportunity for growth. A key strategy for accelerating agricultural expansion is increased private sector involvement in land redistribution, supported by state-sponsored enabling laws, incentives, and monitoring procedures. By 2030, it is probable that the actual agricultural gross value added will have significantly increased thanks to a series of initiatives in five key sectors of the agricultural industry.

One enduring issue associated with Nelson Mandela is the struggle for social justice and human rights. Mandela was a key figure in the fight against apartheid in South Africa and spent 27 years in prison for his activism. Even after his release, he continued to fight for equality and justice for all South Africans, regardless of their race or background.

One example of Mandela's commitment to social justice is the Truth and Reconciliation Commission (TRC) established in South Africa in 1995. The TRC was created to investigate human rights abuses committed during the apartheid era and to promote national unity and reconciliation. Mandela believed that in order to move forward as a nation, it was necessary to confront the injustices of the past and to hold those responsible accountable for their actions.

In his opening address to the TRC, Mandela stated: "Let us never forget that the cause of freedom and justice in this land has not yet been won. We have not yet reached our destination. But each one of us can point to a moment in our lives when we realised that we have the power to shape our destiny.

As altitude increases, there is less air above, leading to less weight pressing down on the surface. Therefore, atmospheric pressure decreases with height.

The Earth's atmosphere is made up of air molecules, and the weight of these air molecules causes pressure on the surface of the Earth. As you go higher in altitude, there are fewer air molecules above you, so there is less weight and less pressure.

For example, if a lot of books are stacked on a table, the weight of the books creates pressure on the table. If some books are taken away, there will be less weight and less pressure on the table. This decrease in atmospheric pressure with increasing altitude is due to the fact that there is less air above you to create pressure.

Tropical cyclone Hagibis developed through various stages before it reached its peak intensity. Tropical Cyclone Hagibis developed from a tropical disturbance to a tropical depression, then to a tropical storm, and finally to a powerful typhoon before weakening and dissipating over Japan.

Initially, the disturbance formed as a tropical depression in the Philippine Sea on October 5, 2019. Over the next few days, it strengthened into a tropical storm and was named Hagibis on October 7.

As it moved northwest towards the Marianas Islands, it intensified further, becoming a typhoon on October 8. Hagibis continued to gain strength, reaching its peak intensity on October 10 as a Category 5 super typhoon with sustained winds of 160 mph (260 km/h) and a minimum central pressure of 915 mb.

After reaching peak intensity, Hagibis began to weaken slightly as it encountered less favorable environmental conditions, such as cooler sea surface temperatures and increased wind shear. It ultimately made landfall on Japan's Izu Peninsula on October 12 as a strong typhoon, causing significant damage and widespread flooding.

In summary, the development of tropical cyclone Hagibis went through the stages of a tropical depression, tropical storm, typhoon, and finally a super typhoon before weakening and making landfall as a strong typhoon.

Large landmasses on earth heat differently than oceans and this interrupt pressure pattern that vary seasonally.

The earth's atmosphere is constantly in motion, with air moving from areas of high pressure to areas of low pressure. High-pressure cells are areas where the air is sinking, leading to higher atmospheric pressure at the surface. Low-pressure cells are areas where the air is rising, leading to lower atmospheric pressure at the surface.

The distribution of these high- and low-pressure cells varies depending on a number of factors, including the temperature of the air and the rotation of the earth. These factors, in turn, give rise to different pressure belts around the earth.

The pressure belts also have an impact on the global climate and weather patterns, as they influence the movement of air masses and the formation of weather systems.
