Explanation:
The chemical reaction between magnesium metal and hydrochloric acid solution is not an acid - base reaction.
An acid - base reaction involves an acid and base to produce salt and water.
- This reaction is called a neutralization reaction.

- When acids and base combines, the main product is a salt in water solution.
That law is known as Boyle's Law, "The volume of a given mass of a gas is inversely related to pressure when the temperature is constant"
Answer:
Explanation By looking at past concentrations of greenhouse gasses in layers in ice cores, scientists can calculate how modern amounts of carbon dioxide and methane compare to those of the past, and, essentially, compare past concentrations of greenhouse gasses to temperature. Ice coring has been around since the 1950s.n:
Salt=compound, soda=liquid solution, aluminum foil=element, milk=colloid,
steel=solid solution
