The chemical formula for water is H2O. A molecule of water consists of two hydrogen atom that bond with one atom of oxygen. The hydrogen and oxygen atoms share electrons because they are covalently bonded.
Water has the molecular weight of 18.1 grams per moles. It also has a high surface tension. This compound is a solvent in which many solutes can dissolve in, including solids, other liquids and gases. For example, methane and ethanol are very soluble in water. It can also exists in three phases. As a solid, it is ice, while its gaseous form is steam. On Earth, water is very abundant, and it makes up about 70 percent of its surface.Learn More
The formula for iron(III) acetate is Fe(CH3CO2)3. It may also be written as Fe(C2H3O2)3, Fe(Ac)3 or C14H27Fe3O18. Iron(III) acetate is most often called basic iron acetate, along with basic iron(III) acetate and iron(III) oxyacetate. It is a solid salt that appears as a brownish-red powder.Full Answer >
Multiplying the total number of moles by 6.02x10^23 will give you total number of atoms present. 6.02x10^23 is known as Avogadro's Number and is the approximate number of atoms in a mole.Full Answer >
Chemical equations must always balance due to the principles outlined in The Law Of Conservation of Matter. This scientific law states that matter cannot be created out of nothing nor can it be destroyed. Therefore, the same amount of matter, in the form of atoms, must exist both before and after the chemical reaction. The matter may change form or location, but it cannot disappear completely or appear out of nothing.Full Answer >
Substances on the left side of a chemical equation are called reactants. Substances that are found on the right side are referred to as products. In a chemical reaction, the reactants are used up and converted into products.Full Answer >
