Answer:
D- beaking bread
Explanation:
The trapped carbon dioxide makes the dough rise, and the alcohol evaporates during the baking process this is an irreversible chemical change.

1 mL is much more precise than 100 mL because 1 mL is a very small and precise unit of measurement</span>
2 moles of Na3PO4 form from 6.0 mol NaOH. Details about stoichiometry can be found below.
<h3>How to calculate number of moles?</h3>
The number of moles of a substance can be calculated stoichiometrically as follows:
3NaOH + H3PO4 → 3H₂O + Na3PO4
According to this equation,
3 moles of NaOH produces 1 mole of Na3PO4
This means that 6 moles of NaOH will produce 6/3 = 2 moles of Na3PO4
Therefore, 2 moles of Na3PO4 form from 6.0 mol NaOH.

A formula unit of the nitrate salt of Q is Q(NO3)2.
<h3>What is IUPAC nomenclature?</h3>
The IUPAC nomenclature was put together by the international Union of Pure and applied chemistry in order to have a uniform way of naming compounds.
We shall now find the names of the compounds;
1) Na* and HPO4²- ; sodium hydrogen tetraoxophoshate V
2) Potassium cation and cyanide anion ; Potassium cyanide
3) Calcium cation and hypochlorite anion; Calcium oxochlorate I
Knowing that the valency of NO3^- is one and that the compound formed between Q and CO3²- has the formula QCO3 we can conclude that a formula unit of its nitrate salt is Q(NO3)2.
