Given: The equation for the synthesis of ammonia is H2(g) + N2(g) → NH3(g). If 12.0 grams of hydrogen are used up by the reaction, how many grams of ammonia will be produced?

The answer to your question is 68 g

Explanation:

Data

mass of H₂ = 12 g

mass of NH₃ = ?

Balanced chemical reaction

               3H₂  +  N₂   ⇒   2NH₃

Process

1.- Calculate the molar mass of H₂

H₂ = 1 x 6 = 6

NH₃ = 2[(14 x 1) + (3 x 1)]

       = 2[14 + 3]

       = 2[17]

       = 34 g

2.- Use proportions to find the mass of NH₃

                 6 g of H₂ 34 g of NH₃

                12g of H₂  x

                        x = (12 x 34) / 6

                        x = 408/6

                        x = 68 g of NH₃

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.

let that person have a turn to speak : )
