Why is there a white coating on calcium?
The white coating on calcium metal is calcium that has reacted with the oxygen in the air to form calcium oxide
Is calcium metal more or less dense than water?
Calcium metal is more dense than water. If you had a block of calcium and dropped it in a container of water, it would sink. Note! Calcium reacts with water! Calcium metal is stored in a container beneath kerosene or another liquid to isolate the metal from air. Calcium will chemically react with the moisture in air and will thus be decomposed.
Gas formed when sulfur burns in air?
Sulfur dioxide, SO2
When 1.326 g of a metal sulfide was roasted in air 0.824 g of oxide was formed If the oxidation number of the metal is 2 what is the molar mass of the metal?

What is the element which burns with white bright flame?
The element that burns brilliantly in the air is magnesium. Magnesium is an alkaline Earth metal with the atomic number 12.
What metal burns in air but only reacts slowly in water?
