If i initially have a gas pressure of 12.12 atms, a volume of 155 ml, and a constant temperature of 200 degrees C, and then i raise the pressure to 14.14 atms, what is the volume of the gas?

Explanation:

The temperature and amount of gas are constant, so we can use Boyle’s Law.

Data:

Calculations:  

so what is the problem with your lab report and whats the subject of the lab report? i will you

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
