Answer: The first one: 2.50 x 10^-5
Explanation:
Equilibrium is a state of balance or a stable situation where the opposing forces cancel each other out and where no changes are occurring.
<h3>How to explain the equilibrium?</h3>
Your information is incomplete. Therefore, an overview will be given. In a chemical reaction, chemical equilibrium is a state where the reactants and products are present in concentrations that have no further tendency to change with time.
In terms of volume changes within a system at equilibrium, the following applies:
- When there is a decrease in volume, then the equilibrium will shift to favor the direction that produces fewer moles of gas.
- When there is an increase in volume, then the equilibrium will shift to favor the direction that produces more moles of gas.
In conclusion, if you increase the pressure of a system at equilibrium, the stress will be reduced by reaction that favors the side with the fewest moles of gas.

Answer:
Salts will be formed and the pH of the new mixture will fall.
Explanation:
What should be: The reaction mixture should be added to the cold acid solution.
The error: Cold acid solution was added to the reaction mixture.
What happens with this?
The neutralization of a solution creates salts. The combination of positive and negative ions in the reaction also forms water. Assuming the pH of the reaction mixture was neutral before the addition of the acid, after the addition of the acid solution the pH will drop. Recall that a neutral solution has a pH of 7. So the pH of this new solution will drop to less than 7 because of the addition of an acid.
If the required procedure for the chemical process was followed, the reaction mixture added to the cold acid would have resulted in a stronger base solution. In other words, the pH of the new solution would be higher.

Answer:
1.2 g
Explanation:
<u>For gallium:-</u>
Mass of gallium= 4.00 g
Molar mass gallium = 69.723 g/mol
The formula for the calculation of moles is shown below:
Thus,
<u>For arsenic:-</u>
Mass of arsenic = 5.50 g
Molar mass of arsenic = 74.9216 g/mol
The formula for the calculation of moles is shown below:
Thus,
According to the given reaction:
1 mole of gallium react with 1 mole of Arsenic
0.0574 mole of gallium react with 0.0574 mole of Arsenic
Moles of arsenic required = 0.0574 moles
Available moles of arsenic = 0.0734 moles
Limiting reagent is the one which is present in small amount. Thus, gallium is limiting reagent.
Moles left unreacted of arsenic = 0.0734 moles - 0.0574 moles = 0.016 moles
<u>Mass = Moles * Molar mass = 0.016 * 74.9216 g = 1.2 g</u>
