A hot water bottle contains 791 g of water at 75 degree Celcius. If the liquid water cools to body temperature (37 degree Celcius), how many kilojoules of heat could be transferred to sore muscles? *Express your answer to two significant figures and include the appropriate units.
a. The solubility of potassium hydrogen carbonate (KHCO3) (100.115 g/mol) in water is 33.7 g/100 mL at 20 oC. Assuming no change in the volume of the water, what is the concentration of a saturated KHCO3 solution at 20 oC? [KHCO3] = ____ M b. How many grams of KHCO3 can be dissolved in 196.5 mL of water at 20 oC?
The solubility of magnesium chloride at 20 degree C is 54.9 g/100 mL of water. That of magnesium iodide is 148.0 g/100 mL. Using this information, do you expect magnesium fluoride to be more or less soluble than magnesium bromide? Explain your reasoning. What are two hazards are associated with using a centrifuge? In this experiment, why is it important to dispose of all waste chemicals as heavy metal hazardous waste? Complete and balance the following precipitation equations. Write the...
The solubility of Li3PO4 in water is 0.034 g per 100 mL. What is the solubility product for this salt? (Ksp = [Li]3[PO4]). Please show your work. Thank you!
A 3.20 g sample of a salt dissolves in 9.10 g of water to give a saturated solution at 25°C. What is the solubility (in g salt/100 g of water) of the salt? (2 points) How much water would it take to dissolve 25 g of this salt? (2 points) If 10.0 g of this salt is mixed with 15.0 g of water, what percentage of the salt dissolves? (2 points)
A solution of potassium chlorate has 20 grams of the salt dissolved in 100 grams of water at 70 degrees Celsius. Approximately how many more grams of the salt can be added to the solution before reaching the saturation point?
The solubility of compound A ịn water at 25°C is 3.00 g/100 mL. In benzene at the same temperature, the solubility of compound A is 4.00 g/50mL. If 3 g of compound were dissolved in 100 mL of water, how much compound would be extracted by three 10-mL portions of benzene?
