Answer:
Mass does not change based on gravity
Explanation:
Mass is how much matter is in an object. That's why we have the same mass on Moon, Neptune, etc.
But weight depends on gravity. That's why our weight on the moon is less than Earth because the Moon's gravity is less than Earth.
The equation of the proton transfer is:
- NaC₆H₅CO₂ + H₂O ⇄ C₆H₅CO₂H + NaOH
<h3>What are acids?</h3>
Acids according to the Bronsted-Lowry definition, are substances that donates one or more hydrogen ions to another substance in a chemical reaction.
The substances that receive the proton are called bases.
Hydrogen ions are considered as protons. The hydrogen ions produced by acids results in a pH of less than 7 for acid solutions.
Considering the given substances, the equation of the proton transfer is given below:
NaC₆H₅CO₂ + H₂O ⇄ C₆H₅CO₂H + NaOH
The compound NaC₆H₅CO₂, sodium benzoate, is a base and accepts protons from H₂O which serves as the acid.
H₂O serve as the acid by transferring protons to NaC₆H₅CO₂ and then, NaOH is formed.

The reason copper coins dull in the first place, is because copper reacts with oxygen in the air and form a layer of copper oxide which is a dull greenish-grey colour. When you mix the salt (sodium chloride) with the vinegar (acetic acid) you form Sodium acetate and Hydrogen chloride.
Answer:
32.7 grams of Zn will remained in the crucible after cooling.
Explanation:
..[1]
..[2]
Adding [1] + 2 × [2] we get:
..[3]
Moles of ZnS in crucible = 0.50 mol
According to reaction [3]. 2 moles of ZnS gives 2 moles of Zn.
Then 0.50 moles of ZnS will give:
of Zn.
Mass of 0.50 moles of Zn =
= 0.50 mol × 65.4 g/mol =32.7 g
32.7 grams of Zn will remained in the crucible after cooling.
