Which Native American group was the first to start fishing? Group of answer choices Archaic Paleo Mississippian Woodland
The Archaic Native American groups were the first to engage in fishing activities. They lived in North America between 8000 BCE and 1000 BCE and utilized rivers, streams, and lakes to supplement their diets with fish.
A saturated solution of NH4Cl at 80c is cooled to 40c.How many grams of NH4Cl will precipitate out
To determine the amount of NH4Cl that will precipitate out when a saturated solution is cooled, we need to consider the solubility of NH4Cl at different temperatures.
The solubility of NH4Cl generally decreases as the temperature decreases. In this case, we have two temperatures, 80°C and 40°C.
To find the amount of NH4Cl that will precipitate, we need to know the solubility of NH4Cl at both 80°C and 40°C. Once we have this information, we can compare the solubility at both temperatures to determine the difference and calculate the amount of NH4Cl that will precipitate out.
Without information on the solubility of NH4Cl at 80°C and 40°C, it is not possible to provide an accurate answer.
