When 50.0 grams of silicon dioxide react with carbon, silicon carbide and carbon monoxide are formed. What mass of carbon monoxide will be produced? SiO2 + C SiC + CO 4. Silver oxide decomposes to form silver metal and oxygen gas. If 3.89 grams of silver are produced, how much silver oxide was used? Ag2O → Ag + O2 Consider the following reaction. If 11.2 grams of aluminum hydroxide are used in the reaction, how much water is produced? H2SO4 + Al(OH)3 → Al2(SO4)3 + H2O

im nkt sure if i balanced the first one or not

Answer 1

2) The balanced reaction is:

C2H2 + 5/2 O2 = 2 CO2 + H2O

Water mass is calculated:

m H2O = 2.36 g C2H2 * (1 mol C2H2 / 26 g) * (1 mol H2O / 1 mol C2H2) * (18 g H2O / 1 mol) = 1.63 g

3) The reaction:

SiO2 + 3 C = SiC + 2 CO

The mass is calculated:

m CO = 50 g SiO2 * (1 mol SiO2 / 60 g) * (2 mol CO / 1 mol SiO2) * (28 g CO / 1 mol) = 46.7 g

4) The reaction:

2 Ag2O = 4 Ag + O2

The mass is calculated:

m Ag2O = 3.89 g Ag * (1 mol Ag / 108 g) * (2 mol Ag2O / 4 mol Ag) * (232 g Ag2O / 1 mol) = 4.18 g

5) The reaction:

3 H2SO4 + 2 Al (OH) 3 = Al2 (SO4) 3 + 6 H2O

The mass is calculated:

m H2O = 11.2 g Al (OH) 3 * (1 mol Al (OH) 3/78 g) * (6 mol H2O / 2 mol Al (OH) 3) * (18 g H2O / 1 mol) = 7.75 g
