BabaBlast [244]

<u>Answer:</u> The molarity of sulfuric acid is 0.0946 M

<u>Explanation:</u>

To calculate the concentration of acid, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is H_2SO_4

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is LiOH

We are given:

n_1=2\\M_1=?M\\V_1=52.87mL\\n_2=1\\M_2=1.25M\\V_2=8.00mL

Putting values in above equation, we get:

2\times M_1\times 52.87=1\times 1.25\times 8.00\\\\M_1=\frac{1\times 1.25\times 8.00}{2\times 52.87}=0.0946M

Hence, the molarity of sulfuric acid is 0.0946 M

Name the phase change in each of these events: (c) Wet clothes dry on a summer day
8090 [49]

The phase change occurs during evaporation. On a hot day, wet clothing is drying. A liquid becomes a gas when it evaporations.

During the process of evaporation, a liquid transforms into a gaseous phase that is not saturated with the evaporating substance. The term "vaporization of a liquid" refers to this process. Clothes start to dry as water vapor escapes from the fabric's surface.

<h3>What is evaporation?</h3>

A liquid turns into a gas through the process of evaporation. Raindrops that "vanish" on a hot day or damp clothing that dries in the sun are good examples of the phenomena. In these instances, the liquid water is evaporating into a gas known as water vapor rather than really dissipating. Global evaporation takes place.
