The chemical reaction for this is:
2 C2H6 + 7 O2 => 4 CO2 + 6 H2O
Solving for CO2 with each reactant will give:
21.0 g C2H6 x (1 mol C2H6/30.08 g C2H6) x (6 mol H2O/2
mol C2H6) x (18 g H2O/1 mol H2O) = 37.70 g H2O
110 g O2 x (1 mol O2/32.00 g O2) x (6 mol CO2/7 mol O2) x
(18 g H2O/1 mol H2O) = 53.04 g H2O
Since the amount of H2O in C2H6 is lower therefore C2H6
is the limiting reactant and the maximum amount of water is only 38 g H2O (2 significant digits)
ANswer:
38 g water
Answer:
minimizing the use of cars can help save the ozone layer by Minimizing the amount of gasoline which damages the ozone layer.
therefore the ozone layer is preserved.
have a nice day.
Answer:
D. 3220
Explanation:
1 km equals 1000 m, so 3.22 km is
3220 m
V= d/t
v=speed
d=distance
t=time
So v= 422/3
v =140.667m/s
