Answer:

The final temperature of both substances at thermal equilibrium is 17.3°C

Explanation:

To calculate the final temperature of both substances at thermal equilibrium -:

First , we calculate the heat of A1 cube as follows -

q= mSΔT

(where q = heat of the cube , m = mass of cube , S= specific heat of cube {0.902j/g°C}, T = Temperature )

Putting the values given in the question ,

$q= 32.5g\times0.902\j/g$ ° $C$ $\times(T_f-45.8$ ° $C)$

$29.315\times(T_f-45.8)J$

Now , calculate the heat of water -

q=mSΔT

Putting values from the question ,

$q=105.3g\times4.18j/g$ ° $C$ $\times (T_f-15.4$ ° $C)$

= $440.154\times(T_f-15.4)J$

Now ,

Heat lost by water A1= Heat gained by water [negative sign about heat lost]

$-29.315\times(T_f-45.8)J$ $=440.154\times(T_f-15.4)J$

$\frac{-(T_f-45.8)J}{T_f-15.4)J} =\frac{440.154}{29.315}=15.0$

$-T_f+45.8$ ° $C=15T_f-231.2$ ° $C$

$(45.8+231.2)$ ° $C$ = $16T_f$

$16T_f=277.03$ ° $C$

$T_f=\frac{277.03}{16}$ = 17.3°C

Therefore , the final temperature of both substances at thermal equilibrium is 17.3°C

GarryVolchara [31]

The Molecular Mass for Phosphorus is 31 grames / mole.

So, 31g. P.....................1 mole
2.3g. P ..........................x mole

 $x= \frac{2,3}{31} = \boxed {0,07} \hbox { moles }$

The hydrolysis of esters in base is called ________. a. the hunsdiecker reaction b. transesterification c. saponification d. the

KengaRu [80]

The hydrolysis of esters in base is called saponification .

So, option C is correct one.

The saponification is the process that involves conversion of fats , oils , lipids into soap and water in the presence of alkaline medium. Saponification is the process of making soap.

During the saponification process, the mixture has an acidity, which tells that it's not safe for usage. After the saponification process is complete, the pH should be a base.The process of formation of carboxylic salt and water by hydrolysis of ester in base is called saponification.
