18 moles of water are produced in the above reaction.
Hope this helps you!
Creo que es 12.32 pero no estoy súper segura
The temperature of the water is 65 Celsius.
<u>Explanation</u>:
The temperature is measured in Celsius and Fahrenheit. Moreover, the kelvin is the SI unit of temperature, and 1 Kelvin is equal to -272.15 Celsius.
So, 272.15 Kelvin would be equal to 0 Celsius. Hence, 325 Kelvin would be around 51.85 degrees of Celsius. To give the iron bar energy, the water should be warmer than 52-degree Celsius. So, the iron bar would gain energy from water when the temperature of the water would be 65-degree Celsius.
My sample would be 4000 years old because on my graph, I had about 9 Virtualium left at trial 4 so I am guessing that it would be 4000 years old.
Increasing the temperature of a gas will lead to an increase in the volume of the gas.
<h3>Temperature and volume of gases</h3>
According to the molecular theory of gases, increasing the temperature of molecules of gas will cause the gas to expand.
This is because the molecules of the gas move faster with an increase in temperature and tend to take up more space.
The theory is also backed by Charle's law. According to Charles' law, the volume of a gas is directly proportional to its temperature.
Thus, increasing the temperature of a gas will cause the volume to increase.
