<span>Hey there!! So the answer is that the heat required to convert a solid into a liquid or vapor, or a liquid into a vapor, without change of temperature. Hope this helped and have a great day!!</span>
Answer:
The Sun is the closest star to Earth.
Answer:
The following statements apply to the general experimental procedure for determining the heat of reaction:
A. Measurements of the temperature of the solution in the calorimeter should be taken at regular intervals for several minutes before the reactant is added.
B. The solution in the calorimeter should not be stirred during the experiment because stirring will slow the reaction
D. Temperature readings need to be taken at regular intervals after the highest temperature reading is observed to determine the rate of heat loss from the calorimeter.
Explanation:
The question is incomplete. The complete question is:
A certain molecular compound M has a solubility in acetone of 0.737g/mL at 10.°C
.Calculate the mass of M that's dissolved in 9.0 L of a saturated solution of M in acetone at this temperature.
Be sure your answer has the correct unit symbol and number of significant digits.
Answer: 6633 g of M is dissolved in 9.0 L of saturated solution in hexane at this temperature.
Explanation:
Given : 0.737g of solute is present in 1ml of solution
i.e 1ml of solution contains = 0.737 g of solute
Thus 9L or 9000ml of solution contains=
Thus 6633 g of M is dissolved in 9.0 L of saturated solution in hexane at this temperature.
Answer:
Methyl Alcohol.
Acetate
Heptane
Dioxane
Explanation:
The boiling point of liquids are measure by observing the gas pressure or vapors temperature. There are few liquids whose boiling point is difficult to measure. The gas pressure differs for every liquid. It is important to observe the vapor pressure also to identify the boiling point. The most difficult boiling point identification is for Methyl alcohol as it has ability to absorb different level of pressure.
