That would be 2 moles of OH- (hydroxide) ions because there are 2 of them associated with each 1 of the group II metal.
For every molecule of a group II metal hydroxide that dissociates, two hydroxide ions (OH⁻) are produced. This is because group II metal hydroxides, such as magnesium hydroxide (Mg(OH)₂) and calcium hydroxide (Ca(OH)₂), dissociate in a 1:2 ratio, releasing two hydroxide ions for each formula unit. Thus, for each molecule of base that dissociates, two OH⁻ ions are generated.
every gas can be ionised, in fact, any chemical can be ionised.
Most non-metals are not highly reactive or an completely inert. However, the Halogens in Group 17 are reactive with nearly every substance on the planet.
No, not every shiny element is a metal. While many metals exhibit a shiny appearance due to their ability to reflect light, some non-metals can also appear shiny. For example, certain allotropes of carbon, like graphite, can have a shiny luster, and some metalloids may also display a shiny surface. Hence, shininess is not exclusively a characteristic of metals.
RNA is read off of the DNA located in every cell.
No. Every element is homogeneous.
No, it can not be used. Every element has colour homogeneity.
+350 million M&M's are produced every year.
Glue is produced in almost every industrialised country in the world
pretty much every recycling centre :)

Hydrogen gas is liberated when metals react with acid. The explanation lies in the fact that the the presence of hydrogen in a substance makes it acidic. so, every acid will contain Hydrogen. When metals reach with an acid, they form their respective salts according to the acid and always liberate hydrogen from that acid. If the acid is H2SO4, then the salt will sulfate of whichever metal reacts with the acid. If the acid is HCl, then the product would be metal chloride.

In every energy transformation, some amount of heat is always produced as a byproduct due to inefficiencies in the process. This is known as the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or transformed.
