We can solve this problem using the formula:
P2 – P1 = ρ g (h2 – h1)
where,
P2 = pressure of the gas manifold = ?
P1 = pressure of the outside air = 754 torr = 100,525 Pa
ρ = density of mercury = 13560 kg/m^3
h2 = height in gas manifold = 76.2 cm = 0.762 m
h1 = height in air = 23.8 cm = 0.238 m
So w can directly find for P2:
P2 = 13560 * 9.81 * (0.762 – 0.238) + 100,525
P2 = 170,229.37 Pa
Convert back to torr:
<span>P2 = 170,229.37 Pa = 1276.83 torr (ANSWER)</span>

<h3>What is the half life?</h3>
The half life is the time taken for only half of the number of the radioactive atoms to remain.
Half life of carbon - 14 = 5730 years.
Initial count rate = 8.0 counts per minute per gram
Count rate at time t = 12.7 counts per minute per gram of carbon
Since;
0.693/t1/2 =2.303/t log (N/No)
0.693/5730 = 2.303/t log (12.7/8)
1.21 * 10^-4 = 2.303/t * 0.2
t = 2.303 * 0.2/1.21 * 10^-4
t = 0.4606/1.21 * 10^-4
t = 3807 years

Answer:Heterogeneous
Explanation:they can be separated by using the method of winnowing
One half of the distance between the nuclei of two atoms bonded together by a single bond is known as the covalent bond radius. When a covalent bond is present between atoms, this radius can be determined. It is the radius of the two atoms because they are equally attracted.
