How many milliliters of 6.32 M hydrobromic acid solution should be used to prepare 5.00 L of 0.700 M HBr? ___ mL​

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

sure im new too!

explanation:

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
