<u>Answer:</u> The products of the given chemical equation are
<u>Explanation:</u>
Protonation equation is defined as the equation in which protons get added in the substance.
The chemical equation for the protonation of carbonate ion in the presence of water follows:
By Stoichiometry of the reaction:
1 mole of carbonate ion reacts with 1 mole of water to produce 1 mole of hydrogen carbonate ion and 1 mole of hydroxide ion
Hence, the products of the given chemical equation are
Answer is: density of the talc sample in air is 4,61 g/cm³.
m(talc) = 13,65 g.
d(talc) = 1,75 g/cm³.
V(talc) = m(talc) ÷ d(talc).
V(talc) = 13,65 g ÷ 1,75 g/cm³.
V(talc) = 7,8 cm³.
d(talc in air) = m(talc in air) ÷ V(talc).
d(talc in air) = 35,97 g ÷ 7,8 cm³.
d(talc in air) = 4,61 g/cm³.
Answer:
Explanation:
Hello,
In this case, by knowing that the used NaOH equals in moles the acid (monoprotic) as shown below, during the titration:
By knowing the volume and the concentration of the NaOH, one obtains:
Thus, the molar mass of the acid is computed based on the previously computed moles and the given mass as follows:
Best regards.
