In the following chemical reaction, how many moles of n2 are needed to completely react with 3 moles of h2? n2 + 3 h2 2 nh3
a. 1
b. 2
c. 3
d. 6

a) 1

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

According to stoichiometry :

3 moles of hydrogen reacts with 1 mole of nitrogen to give 2 moles of ammonia.

Thus 1 mole of hydrogen are needed to completely react with 3 moles of nitrogen.

its going to be mutualism cuz they both benefit from the relationship.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
