Answer:
Yes
Explanation:
Chemical reactions often involve changes in energy due to the breaking and formation of bonds. Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic.
<span>Solar energy arrives and is converted into chemical energy by plants which is eaten by animals and converted again and the animal is either eaten by another animal or dies and is broken down by decomposers and the energy is converted back into basic elements for plants to feed off of with the help of solar energy hence the cycle starts again
sorry this is all i know i hope it helps</span>

Answer:
B?
Explanation:
In the example, the amount of hydrogen is 202,650 x 0.025 / 293.15 x 8.314472 = 2.078 moles. Use the mass of the hydrogen gas to calculate the gas moles directly; divide the hydrogen weight by its molar mass of 2 g/mole. For example, 250 grams (g) of the hydrogen gas corresponds to 250 g / 2 g/mole = 125 moles.
