Calculate the pH of the solution, given the following (H+). Then identify the solution as acidic, basic, or neutral. [H+]=7.94x10^-5 *
4.1; basic
0 6.9; basic
04.1; acidic

4.1 Acidic

Explanation:

pH = -log(H+)

     = -log (7.94x10^-5)

     = 4.10017949757

     = 4.1

any pH under 7 is acidic

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
