If 20.00 moles of calcium reacted, how many grams of …
1122" g CaO" First you need to create the skeletal equation for the reaction. Since calcium oxide (CaO) is produced, oxygen (O_2) is required. Skeletal equation: Ca + O_2 -> CaO Balance the equation based on the law of conservation of mass. Since there are two oxygen atoms on the left, a 2 coefficient is required: " "Ca + O_2 -> 2CaO Now you need to have 2 calcium molecules on the left to
