Answer:2CH_3OH(l)+3O_2(g)\rightarrow2CO_2(g)+4H_2O(l)

Explanation: A chemical change is a reaction in which chemical composition of the substance changes. Some bonds are broken and some new bonds are formed.

The reactants are written in terms of their chemical formula on the left hand side and the products are written in terms of their chemical formula on right hand side with a arrow in between. The chemical symbols are followed by their physical states such as (l) for liquid, (s) for solid, (g) for gas and (aq) for aqueous.

Thus the only reaction producing a gas is 2CH_3OH(l)+3O_2(g)\rightarrow2CO_2(g)+4H_2O(l)

Why does nuclear charge increase as you go left to right across a period
MariettaO [177]

 The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.
