Nitrogen gas (N2) and hydrogen gas (H2) combine to form ammonia (NH3).
2 answers:
Answer: Option (d) is the correct answer.
Explanation:
When nitrogen gas chemically reacts with hydrogen gas then it results in the formation of ammonia gas.
The chemical reaction equation for this will be as follows.
To balance this equation, we need to a multiply by 3 on reactant side, And, we also need to multiply
by 2.
Therefore, the equation which will correctly represent this reaction will be as follows.

Answer:
The percentage yield is 78.2g
Explanation:
Given, mass of propane = 42.8 g , sufficient O2 percent yield = 61.0 % yield.
Reaction - C3H8(g)+5O2(g)------> 3CO2(g)+4H2O(g)
First we need to calculate the moles of propane
Moles of propane = g.mol-1
= 0.971 moles
So, moles of CO2 from the moles of propane
1 mole of C3H8(g) = 3 moles of CO2(g)
So, 0.971 moles of C3H8(g) = ?
= 2.913 moles of CO2
So theoretical yield = 2.913 moles 44.0 g/mol
= 128.2 g
So, the actual mass of CO2 = percent yield theoretical yield / 100 %
= 61.0 % 128.2 g / 100 %
= 78.2 g
the mass of CO2 that can be produced if the reaction of 42.8 g of propane and sufficient oxygen has a 61.0 % yield is 78.2 g
