Which of the following statements is true?

a. nonpolar solvents are useful for dissolving polar solutes.
b. polar solvents are useful for dissolving nonpolar solutes.
c. nonpolar solvents are not useful because they do not form solutions with water.
d. nonpolar solvents are useful for dissolving nonpolar solutes

stir 500 g of cesium chloride into 200 g of water at 20°c. if 127 g sink to the bottom of the
container, what is the solubility of cesium chloride per 100 g of water at 20°c?

a. 186.5
b. 373
c. 127
d. 286.5

43.452

step-by-step explanation:

284 times .153 = 43.452

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
