40
Explanation:
Your trying to find out the meters so your going to divide 3920J by 10 and 9.8
3920/10/9.8
Answer: Oxygen and Carbon
Explanation:
Answer:
The three isomers having the molecular formula 
are drawn in the figure below.
Explanation:
We will use Arrehenius equation
lnK = lnA -( Ea / RT)
R = gas constant = 8.314 J / mol K
T = temperature = 25 C = 298 K
A = frequency factor
ln A = ln (1.5×10 ^11) = 25.73
Ea = activation energy = 56.9 kj/mol = 56900 J / mol
lnK = 25.73 - (56900 / 8.314 X 298) = 2.76
Taking antilog
K = 15.8
