Answer:
Oil and vinegar separate because it is a suspension
Explanation:
When you let suspensions sit the particles begin to layer out, in the salad dressing the oil layers out on top of the vinegar. The two layers of oil and vinegar don't actually dissolve in each other. The layer with the lower density (oil) floats on top of the layer with a higher density (vinegar)
Answer:
A chemical reaction that stores energy is called an endothermic reaction. More energy might be released as products form than the energy needed to break the reactants apart. This chemical reaction will release energy. In other words, it will be an exothermic reaction.
Explanation:
Answer:
b. Lower molar mass.
Explanation:
- <em>Thomas Graham</em> found that, at a constant temperature and pressure the rates of effusion of various gases are inversely proportional to the square root of their masses.
<em>∨ ∝ 1/√M.</em>
where, ∨ is the rate of diffusion of the gas.
M is the molar mass of the gas.
<em>As the gas has a lower molar mass, it will have a higher rate of effusion.</em>
That is Magnesium Chloride.
