What is a correct method for determining how many grams of oxygen will react with 1.00 gram of propane? C3H8(g)  +  5 O2(g)  → 3 CO2(g)  +  4 H2O(g)

What type of bonding is found in the compound PCl3?

In the reaction below how many moles of carbon are needed to produce 66.0 g of carbon monoxide?2 C + O2 → 2 CO

Consider the following balanced reaction. How many grams of water are required to form 62.2 g of HNO3 ? Assume that there is excess NO2 present. Molar masses: H2O = 18.02 g/mol, HNO3 = 63.02 g/mol, NO2 = 46.01 g/mol,NO = 30.01 g/mol.               3 NO2 (g) + H2O(l) → 2 HNO3 (aq) + NO(g)

What is the percent yield for the reaction below If 119.3 g of PCl5 (MM = 208.2 g/mol) are formed when 61.3 g of Cl2 react with 216.5 g of PCl3 (137.32 g/mol)? PCl3(g) + Cl2(g) → PCl5(g)
