A person with swollen gums rinses his mouth with lukewarm salt water and swelling of his gums decreases. This isbecause (1 MARK) a. The gums absorb the salt water solution.b. The salt water solution lowers the temperature of the water in the gums.c. The salt in the solution moves against the concentration gradient.d. The water in the gums moves out due to high concentration of salt in the solution

Tina has a beaker filled with salt and water. If she adds more salt to the beaker, the concentration of the solution will _______. A. increase B. decrease C. equal zero D. stay the same

Jenna put 100 grams of salt into one cup, or 237 mL, of water at room temperature. Only 87 grams of the salt dissolved in the water and the rest stayed on the bottom of the cup. What will happen if she heats the water in the cup? A. the salt will melt B. less salt will dissolve C. the salt will become a gas D. more salt will dissolve

What happens to the rate of dissolution of salt when you stir it after pouring it into a solvent?a.it decreasesb.it increasesc.it decreases by halfd.it stays the same

You are tasked to determine the effect of temperature on the rate of dissolution of salt in water. So you dissolved 10 grams of salt by pouring it into the water, then immediately stirred the solution clockwise 3 times. You then time how long it will take for the salt to disappear in the water completely. The data table below summarizes your experiment. If you increase the amount of salt to 20 grams and do the experiment again, what do you think will be the effect of temperature on the rate of dissolution for this scenario?a.the colder the water, the faster the salt dissolvesb.the colder the water, the more grams of salt can be dissolvedc.the hotter the water, the faster the salt dissolvesd.the hotter the water, the more grams of salt can be dissolved
