explain why the freezing of water into ice causes the cracks to widen
Answer:
The freezing of water into ice causes the cracks to widen because it occupy more space.
Explanation:
When the water change its state of liquid to solid state due to decrease in temperature, it contracts means occupy less space but when the temperature reaches to 4 degree Celsius, it starts to expand. When the temperature goes below 0 degree Celsius, it will cause more expansion and occupy more space that causes the cracks to widen.

Answer:
They both combine with The help of valency, which is the combining capacity of elements
Explanation:
I find it easier to understand valency as part of the Bhor’s model of an atom.
In his model, it was stated that electrons are spread around the nucleus in such a way that there are rings around the model. Each ring has a n value. So, k has 1, l has 2, m has 3 and n has 4...
what you need to know to find the number of electrons in each ring is to solve the formula 2n squared
Then, the valency is the 8 minus the number of electrons in the outermost shell. Remember that 8 is max number I;outer most shell. If you try it out for oxygen, you will get the value of 2 remaining, which can be gained if combined with calcium.
Hope it helps

why do you think the purple cabbage indicator used in this experiment is called "red cabbage"? where is it typically used in food?
Answer:
Red cabbage juice contains a natural pH indicator that changes colors depending on the acidity of the solution. The pigment in red cabbage that causes the red color change is called flavin (an anthocyanin). ... At a lower pH, more hydrogen ions are in solution, and therefore the solution is acidic

Which of these is not an example of physical weathering?
Freeze-thaw
Acid rain falling on limestone

An example which doesn't depict physical weathering is acid rain falling on limestone.
Physical weathering involves the breakdown of rock into smaller particles through physical processes such as friction between rocks as a result of wind blowing sand onto rocks, freeze-thaw in colder climates etc and it is usually reversible.
Chemical weathering on the other hand involves the breakdown of rock into smaller particles through chemical processes or reaction such as acid rain falling on limestone and it is usually irreversible.

Explanation:
The attraction between positive and negative ions in an ionic bond. Hence, option D is correct.
What is the electrostatic attraction?The electrostatic force is an attractive and repulsive force between particles caused due to their electric charges.
Ionic bonding is the attraction between positively- and negatively-charged ions. These oppositely charged ions attract each other to form ionic networks (or lattices). Electrostatics explains why this happens: opposite charges attract and as charges repel.

To separate a mixture of hard candies and
marbles, the most efficient method would be
Answer:
depends on the size andt shape i think hand picking would be most efficient.
Explanation:
The most efficient method to separate a mixture of hard candies and marbles would be to use a physical property that is unique to one of the components of the mixture.
In this case, the physical property that can be exploited is the difference in size and shape between the hard candies and the marbles. Since marbles are solid spherical objects and hard candies are irregularly shaped, it is possible to employ a sieving or filtration method to separate them.
A sieve or a mesh with openings smaller than the marbles but larger than the hard candies can be used. By pouring the mixture onto the sieve and shaking it gently, the marbles will be retained on the sieve while the smaller-sized hard candies will pass through the openings and be collected separately.

Waves cause erosion along coastlines and deposit sand away from the shore.
Erosion occurs as surface water carries sediment and the sediment is deposited near oceans and lakes.
Glaciers cause erosion through the movement of large chunks of ice, which are deposited and form depressions.
Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction.
Answer:
Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction.
Explanation:
Erosion can be defined as a geological process which involves the wearing away of earth material and transportation of these material to another location by Natural agents such as wind and water. Erosion involves removal of top soil, rocks and other earth particles by action of wind, glacier and water.
Wind causes erosion by deflation. Deflation is the actual removal of grain of rocks . Generally, it s the lowering of land surface that happens as a result of removal of surface particles(sands grains) by wind. Deflation is usually prevalent in arid areas. This sand can later be picked up and deposited to form sand dunes . Sand dunes are mounds of sand formed by wind . This sands are sheltered by an obstacle. And sand dunes are prevalent in desert and or along the beach. The sand dune grows as sand accumulate.
The way in which erosion and deposition work together to form sand dunes is: Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction.
Exogenic processes refer to the various processes that occur at or near the surface of planet Earth due to the action (influence) of exogenic forces or geomorphic agents.
In Geology, the five (5) evidence of exogenic processes on Earth's surface include the following:
WeatheringStrippingMass wastingErosionDepositionDeposition is typically a consequence of erosion and it usually result in the laying down of sediment on a landform (landmass), which sometimes make the foundation of buildings stronger to withstand stress.
The formation of sand dunes is generally caused as a result of the effect of both erosion and deposition. Sand dunes are formed when sands are eroded from rocks through deflation, which leads to an accumulation of more sand.
Furthermore, the accumulated sands are picked up by strong winds and then deposited in another location against an obstruction.

10 grams of sodium hydroxide, NaOH, is dissolved in 0.25 liters of solution. Determine the molarity (M).
Answer:
1M
Explanation:
The molarity of a substance is defined as the number of moles of the substance divided by how many liters the solution is. NaOH has a molar mass of about 40 grams, meaning that 10 grams of it would be 0.25 moles. 0.25/0.25= a molarity of 1.

Explanation:
this is because a voltaic cell is such a cell where chemical energy gets converted to electrical energy. the energy conversion in the case of an electrolytic cell is from electric to chemical (battery supplies electrons to the anode respectively). So, I feel by adding a cell or battery, we can change the way energy conversion takes place, thereby changing the process.

Answer:
1. 2.1 moles of Mg
2. 0.72 mole of Mg(OH)2
Explanation:
1. We'll begin by writing the balanced equation for the reaction. This is given below:
3Mg + 2AlBr3 —> 3MgBr2 + 2Al
From the balanced equation above, 3 moles of Mg reacted to produce 2 moles of Al.
Therefore, Xmol of Mg will react to produce 1.4 moles of Al i.e
Xmol of Mg = (3 x 1.4)/2
Xmol of Mg = 2.1 moles.
Therefore, 2.1 moles of Mg is required to 1.4 moles of Al.
2. We'll begin by calculating the number of mole in 26g of water, H2O.
This is illustrated below:
Molar mass of H2O = (2x1) + 16 = 18g/mol
Mass of H2O = 26g
Number of mole of H2O =?
Mole = Mass /Molar Mass
Number of mole of H2O = 26/18
Number of mole of H2O = 1.44 moles
Next, we shall write the balanced equation for the reaction. This is given below:
2HNO3 + Mg(OH)2 —> Mg(NO3)2 + 2H2O
Finally, we can obtain the number of mole of Mg(OH)2 used in the reaction as follow:
From the balanced equation above,
1 mole of Mg(OH)2 reacted to produce 2 mole of H2O.
Therefore, Xmol of Mg(OH)2 will react to produce 1.44 moles of H2O i.e
Xmol of Mg(OH)2 = (1 x 1.44)/2
Xmol of Mg(OH)2 = 0.72 mole.
Therefore, 0.72 mole of Mg(OH)2 was used in the reaction.
