Answer:
2.174 gm
Explanation:
PV = nRT n = number of moles
R = gas constant = .082057 L-atm/(K-mol)
T must be in units of K
.870 (3.95) = n (.082057)(35+273.15)
solve for n = .1359 moles
Methane mole weight (CH4) = 16 gm / mole
.1359 moles * 16 gm/mole = 2.174 gm
Answer: B- Chemical bonds are formed. Energy is released in the form of heat.

Grasses can grow where they could not earlier because the soil conditions, water volume, or rate of sunlight have evolved.
Each species of plant requires specific conditions to thrive. These conditions include:
- Nutrients from the soil.
- Sunlight
- Specific amount of water.
This implies that if the conditions for a specific species are not provided in terms of sunlight, radiation, and water, the plant will not grow in that specific zone. In the same way, if the conditions of a zone change and they are not suitable for a plant species the plant will grow even if this was not possible before.
This key idea is the reason why some plants including grasses can now grow in zones where they did not exist before. Some of the factors that have contributed to this are:
- Fertilization: This provides soils with necessary nutrients.
- Climate change: This has affected climate patterns, and therefore it can increase or decrease radiation.
- Irrigation: This increases the amount of water available for plants.

2 x 166.0028 g ---------> 461.0089 g
? g KI -------------> 1.2 g
Mass KI = 1.2 x 2 x 166.0028 / 461.0089
Mass KI = 398.40672 / 461.0089
Mass KI = 0.86 g
