Answer:
<h3>
<u>A). react with acid that is added and make a base.</u></h3>
explanation:
<em>Buffer solutions resist a change in pH when small amounts of a strong acid or a strong base are added.</em>
In a closed system, heat should be conserved which means that the heat produced in the calorimeter is equal to the heat released by the combustion reaction. We calculate as follows:
Heat of the combustion reaction = mC(T2-T1)
= 1 (1.50) (41-21)
= 30 kJ
Explanation:
The atomic number is equal to the number of protons in an atom's nucleus. Hydrogen's atomic number is 1 because all hydrogen atoms contain exactly one proton.
