One step in the industrial production of nitric acid is the reaction of ammonia with oxygen gas. 4NH3(g)+5O2(g)-->4NO(g)+6H2O
balu736 [363]

Answer:

Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 6.4 L of nitrogen monoxide gas

Explanation:

Equation of reaction:  4NH₃(g) + 5O₂(g) --> 4NO(g) + 6H₂O(g)

From the equation of reaction, 5 moles of oxygen gas produces 4 moles of nitrogen monoxide gas

1 mole of a gas at STP occupies a volume of 22.4 L

5 moles of oxygen gas occupies a volume of 5 * 22.4 L = 112 L

4 moles of nitrogen monoxide as occupies a volume of 4 * 22.4 L = 89.6 L

Therefore, 89.6 L of nitrogen monoxide gas are produced from 112.0 L of oxygen

Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 8.0 * (89.6/112

Moles of nitrogen monoxide gas produced from 8.0 L of oxygen gas = 6.4 L of nitrogen monoxide gas

a metal sample has a mass of 7.56 g. the sample is placed into a graduated cylinder previously filled with 20.00 mL of water. If
PtichkaEL [24]

Answer:

4.5g/ml

Explanation:

metal sample has a mass = 7.56 g

cylinder previously filled with water = 20.00 mL

final volume in the cylinder =  21.68 mL

density = \frac{mass}{V_f - V_i}

density = \frac{7.56}{(21.68 - 20.00)}

density = 4.5g/ml
