The answer is all of them. But in a school situation, A would be appropriate. This is because the smoke gets into the smokers lungs, whether it be marijuana or tobacco, and can cause cancer cells to grow in your lungs and enter your bloodstream.
So A is the answer.
I think the correct answer among the choices listed above is option C. The two type of reaction taking place in the process are double-replacement reaction and decomposition reaction. The double-replacement reaction is the reaction between magnesium carbonate and nitric acid while the decomposition is the breaking down of the carbonic acid into water and CO2.
Answer: 
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as 
The expression for is given as:
![K_{eq}=\frac{[NOBr]^2}{[NO]^2[Br_2]}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BNOBr%5D%5E2%7D%7B%5BNO%5D%5E2%5BBr_2%5D%7D)
Thus in the reaction, 
has to be product and 
and 
has to be reactants, the reaction has to be
Answer:
B
Explanation:
Kinetic means the amount of energy giving force
Potential means the amount of energy taken away
