Need some help with this chemistry question! super stuck with the method please help! 7. Given that the second protonation of H2SO4 has a Ka value of 1.2 x 10-2. A H2SO4 bottle is labelled 70 % w/v concentration. Calculate the pH produced by the acid. (ANS: 0.85)

what is the average time it took the car to travel 0.25 meters?

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
