This is the chemical formula for methyl tert-butyl ether (the clean-fuel gasoline additive MTBE): CH3OC(CH3)3
A chemical engineer has determined by measurements that there are .020 moles of carbon in a sample of methyl tert-butyl ether. How many moles of hydrogen are in the sample?

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;

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

the objects have the same charge.
