Answer:

Solid/freezing

Explanation:

Solid has the least energy of all of the phase changes and the more energy is lost the colder its gets then water turns into a solid called ice hope i helped!

If 135.7 J of heat are added to 54.0 g of water initially at 25.0 °C . What is the final temperature of the water?

german

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.

Why are most anions basic in H2O? Give formulas of four anions that are not basic.

AVprozaik [17]

Answer:

The anions that can act as bases (conjugate bases of weak acids) have the capability to hydrolyse water and produce OH− ions. Cl−, Br−NO−3, SO2−4 are all conjugate bases of strong acids that don't have the capability to hydrolyse water and so they aren't basic.
