Answer
<span>How does adding a non-volatile solute to a pure solvent affect the vapor pressure of the pure solvent?
</span>Answer The third option The solvent's vapor pressure will not be affected.
<span>To make a 2.0 M solution, how many moles of solute must be dissolved in 0.50 liters of solution?
Answer C. 1.0 mole solute.

Answer: Molecules only speed up when given energy, such as heating. When you heat water enough, it will boil and turn into water vapor. So, therefore, if water's molecules speed up, it will go into the gas phase
Explanation: As that liquid water is further heated, it evaporates and becomes a gas—water vapor. These changes between states (melting, freezing, and evaporating) happen because as the temperature either increases or decreases, the molecules in a substance begin to speed up or slow down.

<h2>The chemical reaction occurs when one element replaces another compound.</h2>
Explanation:
Chemical reaction : It is the reaction in which two or more substances react to form some new substance .
Like : Burning of fuel etc
We have different types of reactions occurring around us like:
- Combination reaction
- Decomposition reaction
- Displacement reaction
- Double decomposition reaction
- Redox reaction
Displacement reaction
it is a reaction between element and a compound in which more reactive element displaces less reactive from its compound
i.E CuSO₄ + Zn --> ZnSO₄ + Cu
(copper sulphate ) (Zinc sulphate )
In this we follow reactivity series and accordingly we come to know whether the reaction will occur or not .
Like if the above asked reaction is modified as this :
ZnSO₄ + Cu ------> No reaction
This is because copper being less reactive than Zn cant displace zinc .Hence , no reaction occur .
