Answer: False
Explanation: the masses of reactants are always the same as the products in order to conform to the law of conservation of mass.
D) reacts with oxygen
All other are physical properties.
Answer:
8,403,000 grams
Explanation:
1 kg = 1000 grams, so just multiply by a factor of 1000
the answer is c, more heat is being released.
The balanced equation for the formation of ammonia is as follows
N₂ + 3H₂ ---> 2NH₃
stoichiometry of H₂ to N₂ is 3:1
number of H₂ moles reacted - 2.79 g / 2 g/mol = 1.40 mol
if 3 mol of H₂ reacts with 1 mol of N₂
then 1.40 mol of H₂ reacts with - 1.40/3 = 0.467 mol of N₂
mass of N₂ required - 0.467 mol x 28 g/mol = 13.1 g
mass of N₂ formed is 13.1 g
