Explanation:
Molar mass of is 114.23 g/mol. Therefore, its number of moles are calculated as follows.
No. of moles =
=
= 0.043 mol
So, 0.043 moles are releasing 239.5 kcal of heat. Hence, heat released by 1.54 mol will be calculated as follows.
= 8577.44 kcal
Thus, we can conclude that 8577.44 kcal heat is released by the combustion of 1.54 mol of .
the balanced equation for the combustion of ethane is as follows
2C₂H₆ + 7O₂ --> 4CO₂ + 6H₂O
molar ratio of C₂H₆ to H₂O is 2:6
this means that when 2 mol of C₂H₆ react 6 mol of H₂O are produced
for every 1 mol of C₂H₆ that reacts thrice the number of moles of H₂O are produced
therefore when 1.4 mol of C₂H₆ reacts - 3 x 1.4 = 4.2 mol of H₂O are produced
the answer is 4.2 mol
well if you round to the nearest cent the number 0.332 move the decimal down 2 time so it would be 33 it the the answer would be "a"
im sorry if im wrong im trying my best to answer correctly please don't report my answer cause brainly mighty remove my account again.xd
