Answer:
Explanation:
Hello,
In this case, we can compute the change in the solution enthalpy by using the following formula:
Whereas the mass of the solution is 350 g, the specific heat capacity is 4.184 J/g °C and the change in the temperature is 1.34 °C, therefore, we obtain:
It is important to notice that the mass is just 350 g that is the reacting amount and by means of the law of the conservation of mass, the total mass will remain constant, for that reason we compute the change in the enthalpy as shown above, which is positive due to the temperature raise.
Best regards.

Answer:
E\charged battery to provide electronic difference
Despite the fact that, both Cu and Zn are solid, there is a salient difference among them. In the periodic table, Zinc locates above the H2, so it's more active than the hydrogen, but Copper locates below the Hydrogen, so it's less active. That's why, HCl (aq) reacts with Zn (s) -- more active one, but does not react with Cu (s).
Answer:B) Going Down
Explanation:
The higher the concentration of hydro in ions in a solution, the more acidic it is, and the lower the pH is.
