Smog
formed by mixture of smoke and fog
Yes. When two things are directly prortional, that means that as one increases, the other increases at the same rate. So, say you have a 2kg object at an acceleration of 2m/s^2. The force would be 4N. If you have a 3kg object at an acceleration of 2m/s^2, the force would be 6N. If two things are inversely proportional, that means that as one thing increases the other decreases at the same rate. A good example of this is in a chemical reaction. If you increase the surface area of the reactants, the reaction time decreases. They are inversely proportional.
The answer is (3) moles of solute per liter of solution. That is what the definition of molarity of a solution means. The equation is concentration = mol number of solute/ volume of solution.

Check Explanation
Explanation:
The Heat of reaction for the forward reaction is defined as the amount of heat given off or absorbed while the forward reaction is taking place. Mathematically, the heat of reaction for the forward reaction is given as the heat content/heat of formation/Enthalpies of the reaction's products minus the heat content/heat of formation/Enthalpies of the reaction's reactants.
ΔH°run = H°(products) - H°(reactants)
When the heat of reaction is negative, the reaction is said to be exothermic and when it is positive, the reaction is said to be endothermic.
