Assuming the amount of gas remains the same, what happens to the pressure if the temperature increases and volume decrease?

The pressure builds up

Explanation:

Pressure gets hotter and hotter as it is squeezed together and the molecules go faster and creates more energy and ultimately more heat

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

answer : third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol

explanation :

let us write down the given equations

equation 1 :

equation 2 :

equation 3 :

let us use hess's law to find out which 2 equations can be added to get the third equation.

let us reverse equation 2 and multiply it by 2. the new equation that we get is,

equation 4 :

let us add equation 1 & 4

the above equation is similar to equation 3 but has different value for dhrxn.

therefore third trial had the contaminated sample and the correct value for dhrxn should be 1000 kj/mol
