Molecules that make up for the body are continuously broken down or used up. They must be replaced, some nutrients, proteins, provide building materials for that purpose. Other nutrients including proteins vitamins and minerals are needed to regulate body processes
Answer:
Formula Weight of gas sample = 20.1 g/mole => Neon (Ne)
Explanation:
Use Ideal Gas Law formula to determine formula weight and compare to formula weights of answer choices.
PV = nRT = (mass/fwt)RT => fwt = (mass/Volume)RT = Density x R x T
Density = 0.900 grams/L
R = 0.08206 L·atm/mole·K
T = 0.00°C = 273Kfwt = (0.900g/L)(0.08206L·atm/mole·K )(273K)
= 20.1 g/mol => Neon (Ne)
Question A is more testable through a scientific experiment because you have a specific thing you are trying to find out, "which gelatin takes longer to set".
Answer:
The tundra!
Explanation:
It is the only biome that has an average winter temperature of -26 degrees Celsius, gets 12-20 inches of rain per year, and has grazing caribou!
Hope this helps!
