Answer : The molality of a solution is, 0.387 mol/kg
Explanation : Given,
Mass of solute (glycine) = 100.7 g
Mass of solvent (water) = 3.466 kg
Molar mass of glycine = 75.1 g/mole
Formula used :
Now put all the given values in this formula, we get:
Thus, the molality of a solution is, 0.387 mol/kg
This definition would best fit conformational isomers. Two compounds that have different structural formulas, although the number and types of atoms are the same.
Hydrogen and oxygen react under a specific set of conditions to produce water according to the equation: 2H2(g)+O2(g) -> 2H2O(g)
I think, but i hope this helps :)
This is where something called Graham's Law applies. Grahams law says that the rate of effusion is inversely proportional to the square root of the molar mass of a gas. What that means is that the less the molar mass of a gas is, the less quickly the gas effuses (effusion being the rate at which a gas can travel through a small hole). A great way to think about this is that effusion is thought about as though the gas is traveling through a small hole, so smaller particles would be able to go through it with greater ease than would a large particle. I don't know what particular sentences the question asks for are, but the answer should be that gas A (molar mass 4) has the greatest effusion rate, gas B (molar mass 16) has the second fastest effusion rate, and gas C (molar mass 32) has the slowest effusion rate.
Answer:
No oxygen
Explanation:
when something is covered in a blanket it prevents the fire from being able to have any oxygen
