Answer: To calculate for the enthalpy of formation, it is the sum of all values of products - sum of all values of reactants.
Explanation:
I’m not sure what chemical reaction you are referencing to, but I attached an image below to help you see what I’m saying.
The powder is made through a chemical reaction (saponification) between an alkaline base with oils is to be expected that there will always be a residual alkali. PH around <span>11.5
hope this helps!

A compound is 2 or more substances chemically combined, mixtures arent
Answer:
pH = 2.5
Explanation:
Given data:
Concentration of HBr = 0.003 M
pH of solution = ?
Solution:
Formula:
pH = -log[H⁺]
by putting values,
pH = -log [ 0.003]
pH = 2.5
