Answer: 317 joules
Explanation:
The quantity of heat energy (Q) gained by aluminium depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
In this case,
Q = ?
Mass of aluminium = 50.32g
C = 0.90J/g°C
Φ = (Final temperature - Initial temperature)
= 16°C - 9°C = 7°C
Then, Q = MCΦ
Q = 50.32g x 0.90J/g°C x 7°C
Q = 317 joules
Thus, 317 joules of heat is gained.
If the concentration of acetyl chloride is increased ten times the rate of reaction is increased ten times.
The conversion of acetyl chloride to methyl acetate is a substitution reaction. Recall that a substitution reaction is one in which a moiety in a molecule is replaced by another.
In this reaction, the CH3O- ion replaces the chloride ion. In the first step, the CH3O- ion attacks the substrate in a slow step. This creates a tetrahedral intermediate. Loss of the chloride ion yields the methyl acetate product.
The rate determining step is the formation of the tetrahedral intermediate. Since the reaction is first order in the acetyl chloride, if its concentration is increased ten times the rate of reaction is increased ten times.

Answer:</h3>
Final volume is 120 L
<h3>
Explanation:</h3>
- Using the dilution concept, dilution involves adding more solvent to a concentrated solution to make it dilute. This results to a dilute solution with less solute concentration and more solvent.
According to the dilution equation;
M1V1 = M2V2
Where, M1 is the molarity and V1 is the volume of the concentrated solution, while M2 and V2 are the molarity and volume of the diluted solution respectively.
In this case;
M1 = 12.0 M
V1 = 30 L
M2 = 3.0 M
V2 = ?
Therefore;
V2 = M1V1 ÷ M2
= (12 × 30) ÷ 3
= 120 L
Hence, the final volume will be 120 liters
