Answer:
2C2H6 + 7O2 → 4CO2 + 6H2O
or
2 C2H6O2 + 5 O2 = 4 CO2 + 6 H2O
Answer:
C5H7N
C10H14N2
Explanation:
ok so lets lay out this nicely
elements C H N
percentage 74 8.7 17.3
mass number 12 1 14
divided percentage by mass 6.167 8.7 1.2357
now divide the smallest number with the 4.99 7.04 1
rest for instance 1,237 is the smallest.
so 6.167÷1,237
and 8.7 ÷1.237
and 1,237 divide 1.237
now the ratio is C5H7N
now for molecular formula find Mr of C5H7N which is (12×5)+7+14=81
next divide 162.1÷81=2
so now for molecular formula just multipily everythng by 2
C10H14N2
No, when ascending, you would weigh more, and when you descend, you weigh less.
This is due to the difference in the effect of gravity.
