WILL MARK BRAINLIEST !! NEED AMSWER ASAP I HAVE A TEST DUE AT 11:59 tonight. i need it soon The equation shown represents the decomposition of methanol:
CH, OH (1) --> CO(g) + 2H2 (9)
How many liters of Hydrogen gas were produced if 7.805 liters of Carbon Monoxide gas were produced? Assume Standard Temperature

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest

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
