Answer: uranium
Explanation: It’s hard to find when mining and is required for nuclear fission
Total weight = 1 + 35.45 + 3 * 16 = 84.45
H = 1 / 84.45 * 100% = 1.18%
Cl = 35.45 / 84.45 * 100% = 41.98%
O = 48 / 84.45 * 100% = 56.84%
Are there any options for this question
Answer:
<u>the reaction will shift to the left </u>and produce more reactants
Explanation:
Step 1: data given
Kc = 190
Temperature = 1000 K
[CO] = 0.025 M
[H2] = 0.045 M
[H2O] = 0.025 M
[CH4] = 0.046 M
When Q=Kc, the system is at equilibrium and there is no shift to either the left or the right.
When Q<Kc, there are more reactants than products. As a result, some of the reactants will become products, causing the reaction to shift to the right.
When Q>Kc, there are more products than reactants. To decrease the amount of products, the reaction will shift to the left and produce more reactants
Step 2: The balanced equation
CO(g) + 3 H2(g) ⇌ H2O(g) + CH4(g)
Step 3: calculate Q
Q = [H2O][CH4] / [CO][H2]³
Q = (0.025*0.046) / (0.025*0.045³)
Q = 504.8
Q > Kc
This means there are more products than reactants. To decrease the amount of products, <u>the reaction will shift to the left </u>and produce more reactants
