Answer:
Maple syrup will have the higher temperature.
Explanation:
- Adding CaCl₂ to water and maple syrup will rise the temperature of both of them.
Specific heat of maple syrup = 2.01 J/g.°C
.
Specific heat of water = 4.18 J/g.°C.
- Which means that the energy needed to rise the temperature by 1.0 °C of 1.0 g of water (4.18 J) is twice as that needed to rise the temperature by 1.0 °C of 1.0 g of water (2.01 J).
- So, the temperature of maple syrup will be higher than that of water when CaCl₂ is added to both of them.
Answer:
[NaOH] = 0.045 M
[red dye] = 0.031 M
Explanation:
The NaOH and the red dye will not react between them, so, the process that it's occurring is only a dilution. The final volume of the solution will be the volume of the flask, which is 100 mL.
The number of moles (n) of each substance will not vary, and it's calculated by the multiplication of the concentration (C) by the volume (V). If 1 is the initial solution, and 2 the diluted:
n1 = n2
C1*V1 = C2*V2
For NaOH:
C1 = 0.150 M
V1 = 30.0 mL
V2 = 100 mL
0.150*30 = C2*100
100C2 = 4.5
C2 = 0.045 M
For the red dye:
C1 = 0.125 M
V1 = 25.0 mL
V2 = 100 mL
0.125*25 = C2*100
100C2 = 3.125
C2 = 0.031 M
Answer: C a substance that can dissolve other substances
Explanation: A solvent is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. The quantity of solute that can dissolve in a specific volume of solvent varies with temperature

Answer:
The pH of the solution increases.
Explanation:
Acetic acid is a weak acid, this means it does not dissociate completely in aqueous solution.
Sodium acetate on the other hand is a salt which dissociates to give acetate ions ad sodium ion.
Also, sodium acetate is the conjugate base of acetic acid. A mixture of a weak acid and its conjugate base is a buffer solution.
The mixture leads to a greater concentration of acetate ion, CH3COO-. shere is an increase in the pH of the solution.
So, when you are adding sodium acetate to a solution of acetic acid, concentration of acetate anions increases. Thus, there will be a decrease of hydronium ions resulting in pH increase.
