Answer:
The partial pressure of oxygen in the mixture is 296 mmHg.
Explanation:
The pressure exerted by a particular gas in a mixture is known as its partial pressure. So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone.
This relationship is due to the assumption that there are no attractive forces between the gases.
So, in this case, the total pressure is:
PT=Phelium + Pnitrogen + Poxygen
You know:
- PT= 756 mmHg
- Phelium= 122 mmHg
- Pnitrogen= 338 mmHg
- Poxygen= ?
Replacing:
756 mmHg= 122 mmHg + 338 mmHg + Poxygen
Solving:
756 mmHg - 122 mmHg - 338 mmHg = Poxygen
Poxygen= 296 mmHg
<u><em>The partial pressure of oxygen in the mixture is 296 mmHg.</em></u>
carbon dioxide reacts with water to create carbon acid which is a rather weak acid but still acid is acid
hope this helps :)
The following will increase the strength of a copper electromagnet;
Adding more loops to the wire
Increasing the current
Explanation:
An electromagnet, a device that transforms electric energy into magnetic energy, has its magnetic field induced by an electric current. This current must be AC (alternating current) and not Direct Current (D.C) for it to work. Increasing the number of coils in the electromagnet increases the number of field lines of interaction between the current and the paramagnetic material. Increasing the current also makes the magnetic stronger.

Humans sweat to expel toxins.
They also sweat because sweat helps the body cool down. During exercise, body temperature rises, sweat helps the body cool down.
Sweat also contain sodium. Which is why it’s salty.
