Explanation:
Moles of NaOH = 10g / (40g/mol) = 0.25mol.
0.25mol / 500g = 0.50mol / 1000g = 0.50mol/dm³.
The molarity is 0.50mol/dm³.
The Blood Alcohol Level (BAC) will rise. Because it usually peaks about 30 minutes after drinking, a sharp spike at 20 minutes makes sense.
BAC.

Answer:
What is a Metal ? Metals. Metals are opaque, lustrous elements that are good conductors of heat and electricity. Most metals are malleable and ductile and are, in general, denser than the other elemental substances.
Explanation:
Metalloid, in chemistry, an imprecise term used to describe a chemical element that forms a simple substance having properties intermediate between those of a typical metal and a typical nonmetal. ...
Definition: The non-metals are elements on the right of the periodic table
Answer:
Approximately
.
Explanation:
Look up the density
of carbon tetrachloride,
, and glycerol:
- Density of carbon tetrachloride: approximately
. - Density of glycerol: approximately
.
Let
denote the gravitational field strength. (Typically
near the surface of the earth.) For a column of liquid with a height of
, if the density of the liquid is
, the pressure at the bottom of the column would be:
.
The pressure at the bottom of this carbon tetrachloride column would be:
.
Rearrange the equation
for
:
.
Apply this equation to calculate the height of the liquid glycerol column:
.
