Which of the following most likely happens when the volume of a gas increases the number of collisions of gas particles remains same. The number of collisions of gas particles increases. The pressure of the gas remains the same. The pressure of the gas decreases

When the collision of gas particles and the volume of the gas stay the same it causes a chemical.

D. The pressure of the gas decreases!

Explanation:

According to Boyle's Law, there is an inverse relationship between the volume of a gas and its pressure!

So, if the volume of a gas increases, its pressure will decrease; the same thing will happen if the pressure of the gas increases -- the volume will decrease!

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
