the molarity of water is 55.5.

The alkali earth metals have the smallest first ionization energies.

The ending of the second element is changed to -ide

subtract the group number from the atomic number

The empirical formula for a molecule containing 46.8 percent si and 53.2 percent o is in the middle of the two. These added together and divided by two will net the average result.

The ClF2+ ion is bent. (The VSEPR AXE notation is AX2E2 ). The ClF2- ion (AX2E3) is linear.

Helium has the highest first ionization energy and francium has the lowest first ionization energy.

If the electronegativity difference between two atoms is below 1.7, then the two atoms form covalent bond.

If a symbol in a chemical formula has no subscript it means only one atom of that element is present in the compound.

The products in a decomposition reaction depend on what the reactants are in that decomposition reaction. The products will be different depending on the reactants.

Food engineering focuses on inventing ways to make food more accessible to populations. This can be done, for example, by genetic modification.
