Answer:
A substance with a high activation energy is expected to have a slow reaction rate.
Answer:
[Y₂] = 31.25M
Explanation:
Based on the chemical reaction:
2X(g) + Y2(g) ⇌ 2XY(s)
We must define the equilibrium constant, K as:
K = 20 = 1 / [X]²[Y₂]
<em>Where</em> [X] and [Y₂]<em> are the equilibrium concentrations of each gas.</em>
<em />
If [X] = 4.0x10⁻²M:
20 = 1 / [4.0x10⁻²M]²[Y₂]
0.032 = 1 / [Y₂]
<h3>[Y₂] = 31.25M</h3>
The purple roots of beetroot are eaten as a vegetable. I am assuming that they are talking about the actual veg.
Answer:
B
B
A
C
Explanation:
3

4
B. Protonation of acetic anhydride
5
A. 1.97 mmol of vanillin and 8.45 mmol acetic anhydride
6
C. 1 mmol of vanillin and 10.6 mmol acetic anhydride
Molar mass :
CO₂ = 44.0 g/mol
CH₄ = 16.0 g/mol
The balanced equation is wrong ,<span>this is the correct :</span>
<span>CH</span>₄<span> + 3 O</span>₂<span> = CO</span>₂<span> + 2 H</span>₂<span>O</span>₂<span>
</span>
16.0 g -------------> 44 g
184.5 g -----------> mass of methane
mass of methane = 184.5 x 44 / 16.0
mass of methane = 8118 / 16.0
mass of methane = 507.375
moles of Carbon dioxide ( CO₂)
507.375 / 44.0 => 11.531 moles of CO₂
hope this helps!
