Soil has a specific heat capacity of 1.700J/g C. During the day, the temperature of soil in a
flowerpot increased from 15.6°C to 35.5°C. If the energy from the sun was calculated to be 251 175J,
what was the mass of the soil? Show your work.
Answers
Answer:
m = 7.42 kg
Explanation:
Given that,
The specific heat of the soil, c = 1.700J/g C
The temperature of soil in a flowerpot increased from 15.6°C to 35.5°C.
The energy released from the Sun is 251175 J. We need to find the mass of the soil.
We know that,
[tex]Q=mc\Delta T\\\\or\\\\m=\dfrac{Q}{c\Delta T}\\\\m=\dfrac{251175}{1.7\times (35.5-15.6)}\\\\m=7424.62\ g[/tex]
or
m = 7.42 kg
So, the mass of the soil is equal to 7.42 kg.

population - A group of organisms of the same species living in the same area at the same time, and which are capable of interbreeding. community - A group of populations living and interacting with each other in a common habitat.
Explanation:
The competitive exclusion principle tells us that two species can't have exactly the same niche in a habitat and stably coexist. That's because species with identical niches also have identical needs, which means they would compete for precisely the same resources.

Answers
Answer:
No, they will not have the same temperature.
Explanation:
No, they will not have the same temperature.
What is Thermometer?An instrument that measures temperature is a thermometer. It is able to gauge the temperature of solids like food, liquids like water, and gases like air.
Celsius, Fahrenheit, and kelvin are the three most popular temperature measuring units. The metric system includes the Celsius scale. The metric system of measuring also contains units for length (like kilometres) and mass (like kilograms).
Nearly all nations in the world use the metric system as their official unit of measurement, which includes Celsius. The Celsius scale is used to measure temperature in most scientific disciplines.
Therefore, No, they will not have the same temperature.

What is the pH of a 1.0 x 10-4 M solution of KOH?
Answers
Answer:
pH = 10
Explanation:
KOH is a strong base; thus it will completely dissociate:
KOH -> K⁺ + OH⁻
Since it completely dissociates, the concentration of both K⁺ and OH⁻ will be the concentration of KOH given (1.0 x 10^-4 M).
We can then find pOH by taking the negative log of the OH⁻, or hydroxide, concentration:
pOH = -log[OH⁻] = -log[1.0 x 10^-4 M] = 4
At 25 degrees Celsius, pH + pOH = 14. If we solve for pH and then plug in our pOH, we get:
pH = 14 - pOH = 14 - 4 = 10
The pH of a 1.0 x 10^-4 M solution of KOH is thus 10.

1. The total pressure of a gas mixture is 1.05 atm. The mixture contains 55% carbon dioxide, 31% nitrogen, and 14% hydrogen.
What is the partial pressure of the carbon dioxide in the mixture?
Answers
Answer:
0.15
Explanation:
The partial pressure of the carbon dioxide in the mixture is equal to 0.58 atm.
What is Dalton's law?Dalton's law can be described as the total pressure of all gases exerted being equal to the sum of the partial pressures of every gas in the mixture of non-reacting gases.
The total pressure of a gas mixture of gases can mathematically be defined as :
P (total) = P₁ + P₂ + P₃ + ......
Given, the total pressure of a gas mixture = Ptotal = 1.05 atm
The fraction of carbon dioxide in the mixture = 55 % = 0.55
The fraction of nitrogen in the mixture = 31 % = 0.31
The partial pressure of carbon dioxide in the mixture can be calculated as:
P(CO₂) = 0.55× P(total)
P(CO₂) = 0.55× 1.05
P(CO₂) = 0.58 atm
Therefore, the partial pressure of the carbon dioxide in the mixture is equal to 0.58 atm.

If people had not extracted fossil fuels from Earth to use as energy, would this carbon be "cycling" within the global carbon cycle we have defined today?
Answers
Answer: The answer is YES. There would still be recycling of carbon even if it wasn't extracted as fossil fuels for energy use.
Explanation:
Carbon is an element in the periodic table with the atomic number of 12. It has 4 electrons on its outermost shell in the electronic configuration. These are valence electrons which are used to form bonds in a wide range of both organic and inorganic compounds, giving rise to simply molecules like carbondioxide.
CARBON CYCLE is a natural process through which carbon and it's compounds are kept fairly constant through recycling. They are found in fossils fuels such as oil, coal, and natural gas. When these fossil fuels are burnt and used as energy, carbon is released in form of carbondioxide. This is just one of the ways carbon is returned to the atmosphere. Other ways include:
--> respiration of plants and animals
--> decomposition of organic substances
--> action of dilute acids and heat on trioxocarbonates (V) and hydrogen trioxocarbonates (IV).
Carbon is then removed from the atmosphere through:
--> plants in photosynthesis
--> rain water as weak trioxocarbonate (IV) acid.
Therefore, there would still be recycling of carbon even if it wasn't extracted as fossil fuels for energy use because the burning of fossil fuels is not the only way carbon is returned to the atmosphere during carbon cycle.
