If 175.0g of nitrogen is reacted with 250.0g of hydrogen, what is the theoretical yield of the reaction? What is the excess reactant? What is the limiting reactant? Show your work.
Answer:
Nitrogen gas is the limiting reactant
Hydrogen gas is the excess reactant
The theoretical yield is 425 g of ammonia
Explanation:
Equation of reaction: 3H2 + N2 ---> 2NH3
From the equation of reaction, 3 moles of hydrogen gas reacts with 1 mole of nitrogen to produce 2 moles of ammonia gas.
Molar mass of hydrogen gas = 2.0 g
Molar mass of nitrogen gas = 14.0 g
Molar mass of ammonia gas = 17.0 g
Number of moles of hydrogen gas in 250 g = 250/2 = 125 moles
Number of moles of nitrogen gas in 175 g = 175/14 = 12.5 moles
Mole ratio of Hydrogen to Oxygen = 125/12.5 = 10 : 1
Therefore, nitrogen gas is the limiting reactant.
Hydrogen gas is the excess reactant
14 g of nitrogen gas produces 17 × 2 g of ammonia = 34 g of ammonia
175 g will produce (34 × 175)/14 = 425 g of ammonia
Therefore the theoretical yield is 425 g of ammonia

Explanation:
Genesis lays an object on the table in a well-lighted room the object absorbs all visible light waves what color object does genesis see?
Answer:
The object Genesis sees is black.
Explanation:
The color an object reflects represents what the object's color is. For example, if a block reflects blue light, then only blue light is sent to our eyes, and hence we see the block as blue.
If an object absorbs all visible light waves, then, that means there's no visible light reflected, and we cannot see any color the object has. Hence, it is black in our eyes.
Hope this helped!
23) Assuming STP, how many moles are in 30 L SO2?
Answer:
1.34 moles SO₂(g)
Explanation:
At STP 1 mole of any gas occupies 22.4 Liters. So, for 30 Liters ...
moles SO₂(g) = 30L/22.4L·mol⁻¹ = 1.34 moles SO₂(g)
