Draw the structural formula (using C and H) for 2-octene. (ASAP! 65 POINTS!)

Because there are 6 carbon molecules in 2-octene, we will place down 6 carbons. Carbons usually form a backbone, so they will be lay in a flat line. You can then add 3 H on both the Hydrogens at the ending to create symmetry, and keep filling Hydrogen on both sides and try to creat symmetry until you only have 2 H left. Place 1 H above a C and 1 H below a C so the remaining 2 carbons can then double bond to each other and form a complete octet.

lol idk man i guess u gotta ask bill nye the science guy

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
