How to get the absolute zero from the graph for Charles law in Celsius? In this case what would be my value? Please help need it
k0ka [10]

At time t = 273.15 °C, the x-intercept occurs. According to Charles' law, an ideal gas's volume decreases as its temperature rises. At t = 273.15 °C, the graph's x-intercept, volume approaches zero.

<h3>Charles law experiment: what is it?</h3>

Describe the Charles Law experiment. Gases have a tendency to expand when heated, according to Charles' law (sometimes referred to as the law of volumes), an experimental gas law. The Kelvin temperature and the volume will be directly proportional when the pressure on a sample of the a dry gas is held constant, according to a current interpretation of Charles's law.

<h3>Which laws—Charles and Boyles—have similarities?</h3>

Boyle's law is formulated for systems with constant temperature, whereas Charles' law is formulated for systems with constant pressure.

What is the total ionic equation for the following reaction?
schepotkina [342]

Answer: Option (d) is the correct answer.

Explanation:

An equation in which electrolytes are represented in the form of ions is known as an ionic equation.

Strong electrolytes easily dissociate into their corresponding ions. Hence, they form ionic equation.

H_{2}CrO_{4} is a strong acid and Ba(OH)_{2} is a strong bases, therefore, both of them will dissociate into ions.

Thus, total ionic equation will be as follows.

2H^{+} + CrO_{4}^{-} + Ba^{2+} + 2OH^{-} \rightarrow Ba^{2+} + CrO_{4}^{-} + 2H_{2}O
