Answer 1

Explanation:

HEY MATE

ANSWER

ANSWERMass = density × volume

ANSWERMass = density × volumeMass of ethyl aclohol =0.7893×10=7.893g

ANSWERMass = density × volumeMass of ethyl aclohol =0.7893×10=7.893gMass of water =0.9971×20=19.942g

ANSWERMass = density × volumeMass of ethyl aclohol =0.7893×10=7.893gMass of water =0.9971×20=19.942gTotal mass of solution =7.893+19.942=27.835 g

ANSWERMass = density × volumeMass of ethyl aclohol =0.7893×10=7.893gMass of water =0.9971×20=19.942gTotal mass of solution =7.893+19.942=27.835 gVolume of solution after mixing = Density / Mass

Anoxia happens when your body or brain completely loses its oxygen supply. Anoxia is usually a result of hypoxia. This means that a part of your body doesn't have enough oxygen. When your body is harmed by a lack of oxygen, it's called a hypoxic-anoxic injury.

Answer 2

96 mL approximately

ii) Ethanol molecules are smaller than water molecules, so when the two liquids are mixed together the ethanol falls between the spaces left by the water.

iii) Anoxia may result from low atmospheric oxygen pressure, anemia, interference with blood flow, or the inability of tissues to utilize oxygen normally.
