Solvation describes the interaction of solvent with dissolved molecules.
Answer: Tissue
Explanation:
group of organized cells doing specific function is tissue group of organized tissues doing a specific function is an organ a group of organized organs doing a specific function is organ system and a group of organized organ systems doing a specific function would be an organism.
Answer:
Al(s) + 3HCl(aq) → AlCl₃(aq) + 3/2H₂(g).
Explanation:
- We should apply the law of conversation of mass to balance any chemical reaction; that the no. of atoms in the reactants side is equal to that in the products side.
So, the balanced equation is:
<em>Al(s) + 3HCl(aq) → AlCl₃(aq) + 3/2H₂(g).</em>
Answer:
Higher boiling point and lower freezing point
Explanation:
Boiling point is the temperature at which substances goes to gaseous phase form their liquid phase. Liquids boil when vapour pressure of the liquid becomes equal to atmospheric pressure. So boiling point of a liquid is affected by the change in its vapour pressure and vapour pressure is affected by adding a non-volatile solute in it.
Effect of adding non -volatile solute on vapour pressure:
When a non-volatile solute is added to a liquid, it alters the interaction between the liquid particles and prevents the liquid particles to going into gaseous phase which results in decrease in vapour pressure. More energy is needed for the vapour pressure of the liquid to becomes equal to atmospheric pressure. Therefore, boiling point increases.
CaCl2 is a non-volatile solute and hence increases the boiling point of the water.
Effect of adding non-volatile solute on freezing point:
When a non-volatile solute is added to a liquid, it alters the interaction between the liquid molecules. The new solute and solvent interaction prevents the liquid to soldify and requires more lowering in temperature. Therefore, freezing point decreases.
