A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 3.30kg of water at 23.8°C. Dur
Brums [2.3K]

Answer:

T_2= 31.9\°C

Explanation:

Hello there!

In this case, it is possible to propose an energy balance in order to illustrate how the heat released by the reaction is absorbed by the water:

-Q_{rxn}=Q_{water}

Thus, since the heat released by the reaction is -112 kJ (-112000 J), it is possible to define the hear absorbed by the water in terms of mass, specific heat and temperature change:

-(-112000J)=m_{water}C_{water}(T_2-T_1)

In such a way, it is possible to define the final temperature as shown below:

T_2=23.8\°C+\frac{112000J}{3300g*4.18\frac{J}{g\°C} }\\\\T_2= 31.9\°C

Best regards!

A full bottle of water was left outside overnight in freezing temperatures, causing the bottle to crack. No mass was added or re
kodGreya [7K]

Answer:The correct answer is option C.

Explanation;

Water has unique property that is, it expands on freezing.Which is the reason for less density of ice than water. The cracking of the bottle was due to the expansion of water (present inside the bottle) on freezing.

Generally, density is inversely proportional to the volume of the substance.

Density=\frac{Mass}{Volume}

Density\propto \frac{1}{Volume}

As we know ,that water expands on freezing which means that volume increases. And with increase in volume of density decreases.

Hence, the correct answer is option C.
