D. All of the above. Developing medicine, analyzing compounds and producing new product such as plastic all have to deal with chemistry.
Answer:
<span>As the temperature of a liquid solvent increases, the amount of solute that can dissolve in it <u>increases</u>.
Explanation:
The solubility of most solutes in a solvent increases with increase in temperature. This solubility is closely related to the heat of solution, (the heat evolved or absorbed when solute is dissolved in solvent). Hence, majority of solutes when dissolved in solvent absorbs heat and makes the overall heat of solution positive. Hence, in this case more heat provided will increase the rate of solubility.</span>
This is false, because copper is an element.
To be solution, it has to have at least 2 different substances. Solid solution of metals is often called alloy.
