Calcium - Wikipedia
The chemistry of calcium is that of a typical heavy alkaline earth metal. For example, calcium spontaneously reacts with water more quickly than magnesium and less quickly than strontium to produce calcium hydroxide and hydrogen gas. It also reacts with the oxygen and nitrogen in the air to form a mixture of calcium oxide and calcium nitride.

That water is a liquid at moderate temperatures, will freeze to form a solid at lower temperatures, and boil to form a gas at higher temperatures are macroscopic observations. But some properties of water fall into the microscopic domain—what we cannot observe with the naked eye.

Copper - Wikipedia
Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals).This led to very early human use in several regions, from c. 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposefully alloyed with another

A possible extension is to hold a cold piece of metal or glass above the place where you burst the bubbles so that the water vapour that forms during the reaction condenses on the metal or glass. Place approximately 1 g of the magnesium pieces in the test tube, but do not add the hydrochloric acid until everything else is ready to be asseled.

On the other hand, chlorine gas is obtained at the anode during electrolysis of brine is passe on dry calcium hydroxide, it gives a compound calcium oxychloride, used for disinfecting drinking water. Therefore X is sodium carbonate NaCO3, Y is calcium hydroxide Ca(OH)2, G is chorine gas Cl2 gas and Z is calcium oxychloride known as bleaching powder CaOCl2.

Reaction of Aluminum with Water to Produce Hydrogen
Introduction: The concept of producing hydrogen by the reaction of certain metals with water was first proposed in the late nineteenth century (1). In more recent times, a paper by Smith in 1972 described an approach using an amalgamated aluminum surface (2).

Oxide - Oxides of phosphorus | Britannica
Oxide - Oxide - Oxides of phosphorus: Phosphorus forms two common oxides, phosphorus(III) oxide (or tetraphosphorus hexoxide), P4O6, and phosphorus(V) oxide (or tetraphosphorus decaoxide), P4O10. Both oxides have a structure based on the tetrahedral structure of elemental white phosphorus. Phosphorus(III) oxide is a white crystalline solid that smells like garlic and has a poisonous vapour. It

The purpose of this experiment is to determine the gas produced by the reaction of calcium with water and whether it is an acid, a base or neither. Hypothesis Based on known information on the reactants (Calcium – Ca, and Water – H2O), and a bit of assessment, I speculate that the experiment will produce a compound of Calcium oxide, and the gas Hydrogen.

Seven Things That Indie a Chemical Change Is …
Gas bubbles appear after a chemical reaction has occurred and the mixture becomes saturated with gas. The chemical change that creates the gas is completed after the gas bubbles leave the mixture. Examples of this type of reaction are when an antacid is dropped in a glass of water and begins to bubble or when boiling water bubbles.
The term oxidation was first used to describe reactions in which metals react with oxygen in air to produce metal oxides. When iron is exposed to air in the presence of water, for example, the iron turns to rust—an iron oxide. When exposed to air, aluminum metal
