Answer:
Your notation is a bit confusing, let me write it more clearly.
Explanation:
( Temperature in °F − 32) × 5/9 = Temperature in °C
The correct option is (a) NaHS, KHCO3 and NaF
NaHS, KHCO3 and NaF will form an aqueous solution of form basic.
<h3>What is
aqueous solution?</h3>
A solution in which water serves as the solvent is called an aqueous solution. The most common way to display it in chemical equations is by adding to the appropriate chemical formula. For instance, the symbol for a solution of table salt, or sodium chloride, in water is Na+ + Cl.

Answer:
ΔH=15000
J = 15KJ
Explanation:
In this exercise you have find the enthalpy of reaction this is the difference between enthalpy of reactans and products,
For the following equation
H2A(aq) + 2 BOH(aq) → B2A(aq) + 2 H2O(l)
We know that 0.20 moles of BOH reacted with excess amount of H2A solution and 1500. J
so,
(2mol/0,2mol)*1500J=15000J
for de reactions exothermics tha enthalpy is negative so:
ΔH=15000
J = 15KJ
