The balanced equation would be
3H2 + N2 ———> 2NH3
yes, because they are combined in different ratios.
Answer: 34.27903 km
Explanation: for an approximate result, multiply the length value by 1.609 to 21.3 to get answer.
We know that:
f * λ = c
<span>and
E = h*f
so,rearranging:
</span>
<span>E/h = C/λ
given:
h = </span><span>6.90 × 10^2 nm
</span><span>substituting the values:
E = </span> C/λ<span> x h
(c is the speed of light;that is 3x10^8 m/s)
</span> = 3x10^8 x 6.626x10^-34 / 6.90 x10^7m x 6.022x10^23
Hence,
using calculator:
we get,
E = 1.69 x 10^5 Joules
Explanation:
CH4+8/2Cl2—>CCl4+4HCl
that is,1molecule of methane+8/2 molecules of dichlorine—>1molecule of carbon tetrachloride+4molecules of hydrogen chloride
