Before Janet leaves the doctor, she is informed that she needs to pay closer attention to her sodium intake. The Food and Drug Administration (FDA) recommends a maximum of 2.40g of sodium / day. Janet likes salty foods. Salt (such as that found in snacks) contains sodium. Specifically, there are 39.33 g of sodium / 100. g of salt. Janet’s Trail Mix snack contains 1.16g of salt / 100. g of snack.    Based on this information, calculate the maximum amount of the Trail Mix snack that Janet can eat in order to meet her allowed limit of sodium per day.

Pre what will be observed in each experiment below. predicted observation (choose one) experiment Can A will make a louder and stronger fizz than can B. A student has two unopened 33 cL cans containing carbonated water. Can A has been stored in the garage (32°C) and can B has been stored in the fridge (8 °C). The student opens one can at the time, both cans make a fizz. Can B will make a louder and stronger fizz than can A. The fizz will be the same for both cans. There is not enough information to predict which can will make the louder fizz. The bubbles will shrink, and some may vanish. A student sees tiny bubbles clinging to the inside of an unopened plastic bottle full of carbonated soft drink. The student opens the bottle, and hears a loud hiss as gas under pressure escapes from the bottle. The bubbles will grow, and more may appear. The bubbles won't change. I need more information to predict what will happen to the bubbles.

1-38. To entertain children between the ages of 2 and 90, I enjoy popping corks from bottles containing vinegar and baking soda pour about 50 mL of vinegar into a 500-mL plastic bottle. Then I wrap about 5 g of baking soda (which is sodium bicarbonate, NaHCO3) in one layer of tissue and drop the tissue into the bottle I place a cork tightly in the mouth of the bottle and step back. The chemical reaction generates CO2(g) that pressurizes the bottle and eventually bursts the cork into the air. Everyone smiles.
