A limestone is a common form of calcium carbonate. When limestone is subjected to high heat, it becomes calcium oxide and releases carbon dioxide gas. This change in limestone at a given temperature is an example of — a physical change like the melting of ice
a chemical change like the rusting of iron
an igneous change like the melting of rock in a volcano
a reversible change such as hardening melted butter

Asample of ammonia reacts with oxygen as shown. 4nh3(g) + 5o2(g) 4no(g) + 6h2o(g) what is the limiting reactant if 4.0 g of nh3 react with 8.0 g of oxygen? o2 because it produces only 0.20 mol of no. nh3 because it produces only 0.20 mol of no. o2 because it produces two times less no than nh3. nh3 because it produces three times more no than o2.
