<u>Answer:</u> The correct option is 1 mole of acetic acid was required for 2 moles of sodium bicarbonate
<u>Explanation:</u>
We are given:
Average number of drops of sodium bicarbonate = 142
The chemical equation for the reaction of sodium bicarbonate and acetic acid in vinegar follows:
From the stoichiometry of the reaction:
1 mole of sodium carbonate reacts with 1 mole of acetic acid in vinegar.
Hence, the correct option is 1 mole of acetic acid was required for 2 moles of sodium bicarbonate

I cannot come up with a reaction which you can convert directly from Al to H2O.
But you can convert from Al2O3 to H2O by adding HCL solvent.
Answer:
51.859 grams
Explanation:
Given:
Mass of sugar in the crunch cereal per serving= 11.0 grams
Mass of cereal served per serving = 60.0 grams
Molar mass of the sugar (C₁₂H₂₂O₁₁) = ( 12 × 12 + 22 × 1 + 16 × 11 ) = 342 grams
Number of moles of sugar per serving = Mass / Molar mass
= 11.0 / 342
= 0.03216 moles
Now,
0.03216 moles sugar requires 60 grams cereal
for 0.0278 moles of sugar, cereal required = (60 / 0.03216) × 0.0278
or
for 0.0278 moles of sugar, cereal required = 51.859 grams
They all have 2 elections in the outer S orbital, and 4 electrons in the P orbitals.
