Answer:

The final temperature of the water is 25.6 °C.

Explanation:

We have,

Heat added to water is 135.7 J

Mass, m = 54 g

Initial temperature was 25 °C

It is required to find the final temperature of the water. The heat added when temperature is increased is given in terms of specific heat capacity as :

Q=mc(T_f-T_i)

T_f is final temperature

c is specific heat capacity, for water, c=4.184\ J/g^{\circ} C

So,

T_f=\dfrac{Q}{mc}+T_i\\\\T_f=\dfrac{135.7}{54\times 4.184}+25\\\\T_f=25.6^{\circ} C

So, the final temperature of the water is 25.6 °C.

In acidic solution, the breakdown of sucrose into glucose and fructose has this rate law: Rate = k[H⁺][sucrose]. The initial rat
yKpoI14uk [10]

In an acidic solution, the rate change if Sucrose is changed to 2.5 M will be  Rate = k[H⁺][2.51M] as the initial rate of sucrose breakdown is measured in a solution that is 0.01 M H⁺.

<h3>What is the breakdown of sucrose?</h3>

Sucrose is a type of sugar that is made by adding fructose and glucose or the breakdown of fructose will be in the form of glucose and fructose always at different levels of concentration.

In the given acidic solution if the concentration of sucrose changes from 0.01 to 2.5 then both have to add to give the total rate of change in the given reaction and it will be 2.51 M.

Therefore, Rate = k[H⁺][2.51M] as the initial rate of sucrose breakdown is measured in a solution that is 0.01 M H⁺for an acidic solution, the rate change if Sucrose is changed to 2.5 M.
