HELP PLEAS WORTH 25 POINTS A gas has a pressure of 1180 mmHg at a volume of 6.2 L. What will the pressure be if the volume changes to 3.5 L?

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

it's c. elements are placed in rows based on how may valencies electrons have.

the correct answer would be d. hope this !

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
