Carbon monoxide (co) gas reacts with oxygen (o2) gas to produce carbon dioxide (co2) gas. if 1.00 l of carbon monoxide reacts with excess oxygen at standard temperature and pressure, what volume of carbon dioxide is produced?

hloride, what is the mass of calcium in

explanation:

im not exactly sure but i think its b!

gas

explanation:

smoke is the matter of a gas

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
