Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium oxide is more normally made by heating calcium carbonate. Calcium, immediately below magnesium in the periodic table is more reactive with air than magnesium.
Calcium formate - Wikipedia
Calcium formate is the calcium salt of formic acid.It is also known as E238.Under this E nuer it is used as an animal feed preservative within EU, but not in foods intended for people. Calcium formate is stable at room temperature, is inflammable and forms orthorhoic crystals.

1. d It might be easiest to balance the equation with mostly whole nuers: 2 NH 3 + ⁷⁄₂O 2 → 2NO 2 + 3H 2O.The question asks about the amount of oxygen reacting with ONE mole of ammonia, thus cut the ⁷⁄₂ (3.5) of oxygen in half to 1.75 2. c Balance: CH 3CHO + ⁵⁄₂ O
Calcium carbonate - Essential Chemical Industry
Calcium carbonate (limestone) is heated to form calcium oxide (quicklime) and carbon dioxide: It is an endothermic reaction and the equilibrium lies far to the left at low temperatures. Only at about 1200 K does the partial pressure of carbon dioxide exceed atmospheric pressure and the decomposition proceeds to completion.

1.4 Both calcium carbonate and calcium oxide are white solids. The student weighed the white solid before and after heating. Explain why a decrease in mass was observed. Use the equation in part 1.3 to help you answer the question. [2 marks]
An equation is balanced by mass when the nuer of atoms of each element in the reactants equals the nuer of atoms of that element in the products. For example, the equation shown for the decomposition of water has four atoms of hydrogen in the two molecules of water on the reactant side and four atoms of hydrogen in the two molecules of hydrogen gas on the product side; therefore, hydrogen
