Answer 7

write the balanced reaction first

Answer 8

how idk

Answer 9

the reaction is the combustion of ethane, \(C_2H_6\). write the combustion reaction

Answer 10

c2h6 + 02=h20+co2

Answer 11

right ?

Answer 12

it's not an equals sign, it should be an arrow, but yes

Answer 13

now balance it

Answer 14

ok.did then

Answer 15

to calculate heat of reaction when you have heat of formation, you use the formula \[\Delta H_{rxn} = \Sigma \Delta H_{products} - \Sigma \Delta H_{reactants}\]

Answer 16

yes.thanx
