What is the % yield of 7.50g of nitrogen reacted with 1.30g of hydrogen and 5.75 g of ammonia is produced
N2 + 3H2 = 2NH3n(N2) = m(N2)/Mr(N2) = m(N2)/(2*Ar(N)) = (7.50 g)/(2*14 g/mol) = 0.267857 moln(H2) = m(H2)/Mr(H2) = m(H2)/(2*Ar(H)) = (1.30 g)/(2*1 g/mol) = 0.65 mol1/3*n(H2) = 0.216667 mol...

1 liter of water costs $2.00 at MAPCO. How much would 5.0 gal of it cost? Would it cost more than 5 gal of gas? Gas was $2.59/gal todayat most stations.
Answer: 1 gal = 3,79 L therefore 5 x 3,79 x 2 = 37,9 $ 5 x 2,59 = 12,95 $ 5 gal of water cost more expensive to 24,95...

find the mass of magnesium oxide that can be formed by burning completely 30g of magnesium ribbon
2Mg+O2 => 2MgOn(Mg)=m(Mg)/Mr(Mg)=30/24=1,25 molln(Mg)=n(MgO)=>m(MgO)=n(MgO)*Mr(MgO)=1,25*40=50g

Magnesium hydroxide was reacted with hydrochloric acid. The weight of magnesium hydroxide was 1500 grams. What was the weight of magnesium chloride being produced from the reaction?
Mg (OH) 2 + 2HCl = MgCl2 + 2H2On (Mg (OH) 2) = m / M = 1500/58 = 25,86 мольM (Mg (OH) 2) = 24 + 16 * 2...
