Balance this equation. if a coefficient of "1" is required, choose "blank" for that box. c3h6 + o2 → co2 + h2o

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.

This is a combustion reaction in which hydrocarbon burns in the presence of oxygen to form carbon dioxide, water and energy.

The balanced chemical reaction is written as :

23.5

23.5

47.0

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
