Answer:
6 mass
Explanation:
because the si unit of gram is mass
Answer:
3) Neither created nor destroyed. Only converted.
Explanation:
The mixture of alcohol and water is a homogeneous mixture where the components are thoroughly mixed and cannot be separated by naked eyes.
The easiest way to separate alcohol from water is by boiling the mixture. The boiling point of alcohol is lower than that of water. Therefore, alcohol will turn into steam before water. This steam can easily be condensed into a separate container.
<u>Answer:</u> The final temperature of the gas is -220.6°C
<u>Explanation:</u>
To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,

where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
![P_1=6atm\\T_1=-33^oC=[273-33]K=240K\\P_2=1.31atm\\T_2=?](https://tex.z-dn.net/?f=P_1%3D6atm%5C%5CT_1%3D-33%5EoC%3D%5B273-33%5DK%3D240K%5C%5CP_2%3D1.31atm%5C%5CT_2%3D%3F)
Putting values in above equation, we get:

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:


Hence, the final temperature of the gas is -220.6°C
Well first you need to convert all the substances into there other name. For example: you would change #1 to Mg+O=MgO. That would be known as a synthesis reaction.
