Answer:
Adding water to an acid or base will change its pH. Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. When an acidic solution is diluted with water the concentration of H + ions decreases and the pH of the solution increases towards 7.

A medium that works by showing two reaction types is called a differential medium
<h3>Differential media</h3>
Differentia media are one of the numerous culture media used in culturing microorganisms. They are also known as indicator media.
They are called differential media because they are able to make a distinction between two microorganisms growing on them based on the biochemical characteristics of some organisms in the presence of certain indicators or nutrients.

Answer:
No matter how many times you cut it, its chemical properties won't change and it'll still be paper.
Explanation:
Answer: A) 3.21 g
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side.
We are given:
Mass of iron = 5.58 g
Mass of iron sulphide = 8.79 g
Mass of sulphur = x g
Total mass on reactant side = 5.58 + x
Total mass on product side = 8.79 g
Applying law of conservation of mass, we get:
Hence, the mass of reacting sulfur is 3.21 g.
