True. Although nuclear energy itself is renewable, the material (uranium) used in nuclear power plants is not.
Answer:
Ok to solve this you will need to use the Ideal Gas Law Formula which is as follows:
PV = nRT
P= pressure
V= volume
n= # of moles
R= Universal Gas Constant (0.0821 L x atm/mol x K)
T= Kelvin temperature
1.Simplify the Ideal Gas Law formula to what you need to solve for:
P = (nRT)/ V
2. List all you components as follows (this makes the process easier):
P = ?
V = 45.4 L
n = 0.625 mol
R = 0.0821 L x atm/ mol x K
T = 249 K
To find the Kelvin temperature K = C + 273
3. Plug in all your components in your set up formula:
P = [(0.625 mol)(0.0821 L x atm/ mol x K)(249 K)] / (45.4 L)
4. Cross out all similar units so the only thing left is atm because you are trying to find pressure.
P = [(0.625)(0.0821atm)(249)] / (45.4)
5. Multiply through and simplify
P = 0.28 atm
B. is the correct answer.

Explanation:
Plants serve as the main source of nutrition for humans as well as provide many products for human use, such as firewood, timber, fibers, medicines, dyes, oils, and rubber.
Plants are multicellular eukaryotic organisms whose mode of nutrition is mainly autotrophic.
Plants play many important roles in life more especially that of producing food on which many other organisms depend on.
Some of the important ways by which plants support human life include:
- Provision of food: plants trap the energy of the sunlight and through the process of photosynthesis produce food on which other living organisms such as animals depend on.
- Provision of oxygen: during the process of photosynthesis, plant release oxygen into the atmosphere which is needed by animals for respiration.
- Recycling of water: through the process of transpiration occurring in leaves of plants, water is recycled in nature.
- Provision of other products such as timber, fibers, medicines, dyes, oils, and rubber.
Therefore, plants serve as the main source of nutrition for humans as well as provide many products for human use, such as timber, fibers, medicines, dyes, oils, and rubber.
