I think the correct answer from the choices listed above is the latter option. The point where the blue line intercepts the temperature axis is <span>the theoretical zero volume temperature of a gas. It is apparently the temperature of the gas when the volume is zero. Hope this helps.</span>

Answer:

The theoretical zero volume temperature of a gas.

Explanation:

The experimental data for effect of temperature on Volume of a gas is plotted in the graph. The graph is a straight line. It has been extrapolated where dash line meets the temperature axis. This point shows the temperature that the gas would have if it had zero volume. Experimentally, this data is not obtained but theoretically measured by extrapolating the volume versus temperature curve.

Thus, the point where blue line meets is the theoretical zero volume temperature of  a gas.

A saturated solution of calcium hydroxide contains 1.85 g of solute in 100. mL of solution. What is its molarity
Leona [35]

Answer:

M=0.250M

Explanation:

Hello!

In this case, since the molarity of a solution is computed by dividing the moles of solute by the volume of solution in liters, we first need to compute the moles of solute knowing that the molar mass of calcium hydroxide is 74.1 g/mol as follows:

n=1.85g*\frac{1mol}{74.1g}=0.0250mol

Next, since the 100-mL solution is also expressed in liters by 0.100 L, we directly compute the molarity as shown below:

M=\frac{0.0250mol}{0.100L}\\\\M=0.250M

Which is expressed in molar units that are mol/L.

Best regards!

How can you estimate the pH range of an indicator’s color change? Why do some indicators have two separate pH ranges?
erastova [34]

The color change of a pH indicator is caused by the dissociation of the H+ ion from the indicator.

<h3 /><h3>What is indicator?</h3>

In science, a marker capability or a trademark capability of a subset An of a set X is a capability characterized from X to the two components set {0, 1}, normally signified as, and it demonstrates whether a component in X has a place with A. Markers are insights used to gauge current circumstances as well as to figure monetary or financial patterns. In the realm of money management, pointers regularly allude to specialized diagram designs getting from the value, volume, or open revenue of a given security.
