Carlotta adds too much salt to her soup. She recalls that evaporation can be used to separate salt from salt water, so she plans to leave the soup on the stove on low heat until the soup is less salty. Which will most likely happen to her soup?
The soup will become saltier because evaporation removes the water and leaves the salt behind.
The procedure will make the soup less salty because the salt will evaporate and leave the pot.
The saltiness of the soup will not change because both salt and water will evaporate.
The heat will cause the soup to become more salty because more salt dissolves in hotter water

the answer for sodium is 0.186

the answer for rubidium is 0.251

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.

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.
