Answer:
a. moles divide by volume
Explanation:
Molarity, denoted by symbol M, refers to the molar concentration of a solution. It is calculated using the formula as follows:
Molarity = number of moles of a solute ÷ volume of the solvent
Since, number of moles (n) has the unit: moles and volume (V) has the standard unit: Litres, then the unit for molarity is moles/litre or M.
Answer: The reactants
Explanation: These are the substances that go into a chemical reaction and start it.
Complete question is;
When solid materials are heated.the heat absorbed/added to the materials caused the materials to change its form from?
Answer:
From solid to liquid
Explanation:
When we heat solid materials, the heat causes the forces of attraction between the molecules to become weaker and as such, the material becomes more loose than it was in the solid state. As a result, the material now becomes a liquid because the molecules now have lesser forces of attraction and are a bit loose.
