What is the chemical equation for calcium and water? …

So one mole of calcium reacts with two moles of liquid water to produce one mole of a solid white product called calcium hydroxide [also known as the mineral portlandite], and one mole of hydrogen gas. The hydrogen gas is seen as bubbles that form on the surface of the calcium metal as it reacts.

How to Make Hydrogen Gas (4 Methods) - ThoughtCo

The main safety consideration is making certain hydrogen gas isn''t allowed to mix with oxygen in air. Nothing bad will happen if it does, but the resulting air-hydrogen mixture is much more flammable than hydrogen on its own because it contains oxygen, which acts as an oxidizer. Store hydrogen gas away from an open flame or other ignition source.

The flowsheet for the direct generation of hydrogen using steam reforming of naphtha on-board vehicle, which is suggested here, is shown in Fig. 1.The process can be described as follows: naphtha feedstock is vaporized and passed through a bed of zinc oxide to remove sulfur contamination, which is a potential poison for reforming alysts and fuel-cell electrodes.

Single replacement reactions (article) | Khan Academy

A single replacement reaction, sometimes called a single displacement reaction, is a reaction in which one element is substituted for another element in a compound.The starting materials are always pure elements, such as a pure zinc metal or hydrogen gas, plus an aqueous compound. When a replacement reaction occurs, a new aqueous compound and a different pure element will be generated as products.

Who created calcium

Calcium is a fairly reactive metal (and thus not found in metallicform in nature). The most commonly found calcium compound iscalcium carbonate, which makes up limestone, coral reefs, seashells

What is the reaction between Calcium Carbonate and

When,chemists want HCl without water, they get it out of a gas cylinder, and call them hydrogen chloride. Calcium carbonate is not very soluble in water, but calcium chloride is, so you would probably start with solid calcium carbonate and HCl solution, and end with çslcoum and chloride ions in solution.
