Methanol is an alcohol with one C atom.
Methanol is also called methyl alcohol. The suffix -ol means the molecule has an -OH group attached to the carbon chain. The word methyl means the molecule has 1 C atom with 3 hydrogen atoms bonded to it.
Alcohols have -OH groups attached to the chain of C atoms.

Writing methanol as CH3OH highlights the structure of the molecule more accurately. It shows that methanol consists of a methyl group (CH3) attached to a hydroxyl group (OH), which is important for understanding its chemical properties. The formula CH4O could be confusing as it may imply a different structure or composition.
Hydroxide generally refers to the hydroxide ion.
In Methyl alcohol the OH group is bonded covalently and behaves differently.
Alcohols and hydroxides are not the only sumestances to contain the OH group either, a number of acids do as well.
The reaction between salicylic acid and methanol typically involves esterification to form methyl salicylate (oil of wintergreen) and water. The chemical equation is: Salicylic acid + Methanol → Methyl salicylate + Water
The molecular formula for sodium phosphate is typically written as Na3PO4. The subscript "1" is usually not included in chemical formulas when there's only one atom of an element, unless it's necessary to distinguish isomers.
Assuming that the questioner would have written BaCl2 instead of BaCI2, if typographic resources were available to do so, the answer is "barium and chlorine". The formula as written shows the presence of barium, carbon, and iodine, but this formula does not correspond to any known compound.
The last part in the chemical formula of a binary ionic compound is usually the anion, which is negatively charged and is represented by its element symbol. It is written after the cation in the formula to show the complete chemical composition of the compound.
It is the chemical formula for Acetic Acid (usually written as CH3COOH)
