Answer with Explanation:
Water is a compound because it consists of two types of atoms (Hydrogen and Oxygen) that are chemically bonded. An "element" only consists of one type of atom, therefore, water is not an element but a compound. Its chemical formula is:
. This means that water consists of 2 atoms of Hydrogen that are bonded to an atom of Oxygen. Take note that a compound is different compared to the elements that it is made of. For example, water is essentially liquid in its form but it is different from the atoms of Hydrogen and Oxygen, which are gas in form.

Answer : It is true.
Explanation : Proof is a device which is usually used for measuring the amount of alcohol present in alcoholic beverages. It involves a method of measuring the alcohol content of spirits where we can calculate the proof of a spirits product by multiplying the percent of alcohol by volume by the factor 2.
Example : If a spirit product that has a 40% alcohol content by volume in the beverage is 80 proof.
40 multiplied by 2 = 80.
