c because it acts as it its the spine of a flower to help keep it up
Answer:
<h2>C 28 tonnes</h2>
Explanation
7 tonnes-8.5 ammonia
1 ton will be 8.5/7=1.21
we now know what 1 ton of nitrogen is equal to
so now,34/28 that is equal to 1.21
1.21=1.21
So the answer would be C. 28 tonnes
Thanks!

I think experiments work in a lab better than the natural world because you got all the equipment that you need in the lab
Answer: 2.744 x 1025 molecules
Answer:
8.08 × 10⁻⁴
Explanation:
Let's consider the following reaction.
COCl₂(g) ⇄ CO (g) + Cl₂(g)
The initial concentration of phosgene is:
M = 2.00 mol / 1.00 L = 2.00 M
We can find the final concentrations using an ICE chart.
COCl₂(g) ⇄ CO (g) + Cl₂(g)
I 2.00 0 0
C -x +x +x
E 2.00 -x x x
The equilibrium concentration of Cl₂, x, is 0.0398 mol / 1.00 L = 0.0398 M.
The concentrations at equilibrium are:
[COCl₂] = 2.00 -x = 1.96 M
[CO] = [Cl₂] = 0.0398 M
The equilibrium constant (Keq) is:
Keq = [CO].[Cl₂]/[COCl₂]
Keq = (0.0398)²/1.96
Keq = 8.08 × 10⁻⁴
