Why is it important to know the properties of both solutes and solvents when preparing a solution that is expected to meet a certain need? Does this involve a chemical change or a physical change? Explain

A solution is consist of solute and solvent and they both together determine the properties of complete solution. It is important to know the properties of both solute and solvent because they both depend on each other to meet a certain need, for example: the intermolecular forces between solutes and solvents determine the solubility of solute in solvent and if solutes must be completely dissolved in the solvent for a homogenous mixture.

The combination of solute and solvent to form a solution is a physical process and not a chemical one because it des not change the chemical properties of solute and solvents.

58750.08068 is the answer i think

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
