Answer:
The correct answer is:
HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l)
Explanation:
When aqueous solution of hydrogen chloride reacts with aqueous solution of sodium hydroxide to give aqueous solution of sodium chloride and water.
1 mole of hydrogen chloride reacts with 1 mol of sodium hydroxide to give 1 mole of sodium chloride and 1 mole of water.

Answer:
Explanation:
Density is found by dividing the mass by the volume.
The mass of the liquid is 12.7 grams.
We know that 15 mL of this liquid was added to a 50 mL graduated cylinder. Therefore, the volume is 15 mL. The 50 mL is not relevant, it only tells us about the graduated cylinder.
Substitute the values into the formula.
Divide.
Round to the nearest hundredth. The 6 in the tenth place tells us to round the 4 to a 5.
The density of the liquid is about 0.85 grams per milliliter and choice A is correct.
