The number of moles of hydrogen is equal to the number of moles of nitrogen.
According to the ideal gas equation
PV = nRT
where
- P = the pressure of the gas
- V = the volume of gas
- n = the total amount of ideal gas (moles)
- R = the universal gas constant
- T = the temperature
In the problems there are two identical cylinders means, V₁ = V₂
The pressure inside each of two identical cylinders is equal to atmospheric pressure means, P₁ = P₂
Both gases are at the same temperature, means T₁ = T₂


n₁ = n₂
So the total amount of hydrogen gas is equal to total amount of ideal nitrogen gas.

Answer:
Higher levels of organization are built from lower levels. Therefore, molecules combine to form cells, cells combine to form tissues, tissues combine to form organs, organs combine to form organ systems, and organ systems combine to form organisms.
Biomass is organic, meaning it is made of material that comes from living organisms, such as plants and animals. Biomass<span> contains </span>energy<span> first derived from the sun: Plants absorb the sun's </span>energy through<span> photosynthesis.
