Answer:
magnesium + water == magnesium oxide + hydrogen
Answer:
A. the iron atoms are gaining kinetic energy
Explanation:
when the iron melted and solidifies it loses potential energy and changes to kinetic energy
<u>Answer:</u> The partial pressure of carbon dioxide is 858 torr
<u>Explanation:</u>
Dalton's law of partial pressure states that the total pressure of the system is equal to the sum of partial pressure of each component present in it.
To calculate the partial pressure of hydrogen gas, we use the law given by Dalton, which is:
We are given:
Total pressure of the carbonated drink, = 890 torr
Vapor pressure of water, = 32 torr
Putting values in above equation, we get:
Hence, the partial pressure of carbon dioxide is 858 torr.
Considering the Dalton's law, the total pressure of the tank is 5.95 atm.
<h3>Dalton's law</h3>
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:
where n is the amount of gases present in the mixture.
This relationship is due to the assumption that there are no attractive forces between the gases.
<h3>Total pressure of the tank</h3>
A tank of gas has partial pressures of nitrogen and oxygen equal to 1.61 atm and 4.34 atm, respectively.
The total pressure of the tank is calculated as:
So, replacing the respective values:
Solving:
Finally, the total pressure of the tank is 5.95 atm.
