Explanation:
A. to make it mix better
B. using a spatula
C. fractional destilations
Answer:
The rise in sea level it will be of 0.08 Km.
Explanation:
The relation between volume (V) and mass (m) is density (δ):
δ = m / V
First, knowing the volume of ice in the Antarctic and the density of the ice, it is possible to calculate the mass of ice that will melt:
m = δ.V =
The mass of ice is 2.77x1022 so, the mass of water entering the oceans is the same.
Second, knowing the mass of water and the density of water, it is possible to calculate the volume of water entering the oceans:
V = m / δ =
Third, assuming that the oceans of the world cover an area, A, of about 3.62 x 108 km2 and that the increase in volume of the oceans can be calculated as A x h:
h = V/A =
Answer:
86
Explanation:
The reaction that takes place is:
- C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O
First we <u>convert moles of ethanol to moles of water</u>:
- 1.6 mol ethanol * = 4.8 mol H₂O
Then we <u>convert moles of water to grams of water</u>, using its molar mass:
- 4.8 mol H₂O * 18 g/mol = 86.4 g
So 84.6 grams of water will be produced.
