The pressure, in mmHg, exerted by only the oxygen gas is 720.8 mmHg
<h3>Pressure of gas collected over water</h3>
The total pressure of a gas collected over water is given by P = P' + p where
- P = pressure of oxygen gas and
- p = vapour pressure of water at 25 °C = 25 mmHg
Making P' subject of the formula, we have
P' = P - p
Since the total pressure of oxygen plus water vapor is P = 745.8 mmHg, substituting the values of the variables into the equation, we have
P' = P - p
P' = 745.8 mmHg - 25 mmHg
P' = 720.8 mmHg
So, the pressure, in mmHg, exerted by only the oxygen gas is 720.8 mmHg

The environmental conditions of the ocean are:
- Light availability
- Oxygen levels
- Water movement
- Salinity
- Density and
- pH.
<h3>What are the environmental impacts on the ocean?</h3>
In our oceans, there are known to be a lot of environmental conditions that are known to often affect the growth, survival and also the productivity of marine organisms. These are the ones listed above.
Note that the increased concentration of chemicals, e.g. nitrogen and phosphorus is one that can be harmful to marine life.
Hence, The environmental conditions of the ocean are:
- Light availability
- Oxygen levels
- Water movement
- Salinity
- Density and
- pH.

Answer:
Explanation:
We know we will need an equation with masses and molar masses, so let’s gather all the information in one place.
M_r: 261.34 233.39
Ba(NO₃)₂ + Na₂SO₄ ⟶ BaSO₄ + 2NaNO₃
m/g: 75.00
1. Moles of Ba(NO₃)₂
2. Moles of BaSO₄
The molar ratio is (1 mol BaSO₄/1 mol Ba(NO₃)₂
3. Mass of BaSO₄
