Answer:
the pressure (torr) of theH₂ gas is 736.2 torr
Explanation:
Given that
The H₂ gas produced in a chemical reaction is collected through water in a eudiometer; during this process, the gas collected contains some droplets of water vapor along with these gas.
So; the total pressure in the eudiometer = Pressure in the H₂ gas - Pressure of the water vapor
Where;
= total pressure in the eudiometer = 760.0 torr
= Pressure in the H₂ gas = ???
= Pressure in the water vapor = 23.8 torr
Now:
= +
- = + -
= - +
= (- 23.8 + 760) torr
= 736.2 torr
Thus; the pressure (torr) of theH₂ gas is 736.2 torr
The answer to this question is:
The mobility of electrons.

Answer:
B, adding an indicator to a solution to test its acidity
Explanation:
Answer:they are the same because they have the same thing in common
Explanation:
Answer:
1.74 g/mL
Explanation:
Step 1: Given data
Mass of magnesium: 4.80 g
Volume of water displaced: 2.76 mL
Step 2: Calculate the volume of the piece of magnesium
The volume of the piece of magnesium is equal to the volume of water displaced in the graduated cylinder.
Step 3: Calculate the density of magnesium
The density of magnesium is equal to its mass divided by its volume.
ρ = m / V
ρ = 4.80 g / 2.76 mL
ρ = 1.74 g/mL
