Sodium (na) reacts with chlorine gas (cl2) to form sodium chloride (nacl) as shown in the equation

2na+cl2=2nacl

if 4 moles of sodium react, how many moles of chlorine gas will react?

Answer : 2 moles of chlorine gas will react with the 4 moles of sodium.

Solution : Given,

Moles of sodium, (Na) = 4 moles

The given balanced chemical reaction is,

From the given balanced reaction, we conclude that

As, 2 moles of sodium(Na) react with 1 moles of chlorine gas

So, 4 moles of sodium(Na) react with moles of chlorine gas

Therefore, 2 moles of chlorine gas will react with the 4 moles of sodium.

calculate how many grams of ammonia can be produced from 4.21 grams of

n2 + 3h2 = 2nh3

my answer:

25.0g n2 x (1 mol/ 28.0gn2) x (2 mol nh3/ 1 mol n2) x (17.0g nh3/ 1 molnh3) = 30.36g n2

25.0g h2 x (1 mol h2/ 2.00g h2) x (2 mol nh3/ 3 mol h2) x (17.0g nh3/ 1 mol nh3) = 141.67g h2

lr = n2
