Wait a second...I am sorry I don't know the answer but I have something to tell you.
It is not necessary that in alcohols, OH should be at the end of a chain .
It can be anywhere in the chain..
The equilibrium concentration of N₂ : 1.992
<h3>Further explanation</h3>
Given
Kc = 6.0 x 10⁻² at 500°C
0.253 M H₂ and 0.044 M NH₃
Reaction
3H₂(g) + N₂(g) = 2NH₃(g)
Required
The equilibrium concentration of N₂
Solution
Kc for the reaction :
Scientists use scientific notation to communicate extremely small measurements. Hence, option A is correct.
<h3>What scientific notation?</h3>
Scientific notation is a way of writing very large or very small numbers.
Scientists use scientific notation to represent very small or very large numbers because this notation increases the
- accuracy of measured quantities.
- convenience in using the numbers.
- the number of significant figures.
- precision of measurements.
Hence, option A is correct.

I think the correct answer from the choices listed above is option C. It would be Cl2 (g) + 2Kl (s) = 2KCl (s) + l2 (g) that <span>describes a single-replacement reaction where Cl replaces I. Hope this answers the question. Have a nice day.</span>
