Answer:
Mass of KNO3 in the original mix is 146.954 g
Explanation:
mass of in original 254.5 mixture.
moles of
moles of
= 0.2926 mol of BaSO4
Therefore,
0.2926 mol of BaCl2,
mass of
= 60.92 g
the AgCl moles
= 1.3891 mol of AgCl
note that, the Cl- derive from both,
so
mole of Cl- f NaCl mol of Cl-
mol of NaCl = 0.8039 moles
then
KNO3 mass = 254.5 - 60.92-46.626 = 146.954 g of KNO_3
Mass of KNO3 in the original mix is 146.954 g
Answer: An Element
Explanation:
An element is a substance that cannot be split into smaller substance. It is made up of one kind of atom and can exist either as molecules (e.g nitogen) or an atom (e.g argon).
Answer:
mechanical energy to electrical energy to light energy
boyles law states that the volumes of a gas will decrease as pressure increases if the temperature remains constant.
charles law states that the volume of a gas will increase as temp increases if the pressure remains constant.
gay-lussacs law states that the pressure increases as temp increases if the volume remains constant.
Answer:
from the small intestine (RE = retinyl ester; ROH = ret- inol. CM = chylomicron remnant). is split at least one intact molecule of retinol, retinal.
