The model that should show the corresct representation of xenon gas is one in which the gas molecules are isolated and monoatomic.
<h3>What is a noble gas?</h3>
A noble gas is a member of group 18 of the periodic table. Noble gases are known not to interact with each other and occur as monoatomic particles.
The images are not shown here hence the question is incomplete. However, we do know that any of the models that show individual monoatomic particles is a representation of xenon gas.

Answer:
Explanation:
H3PO4(aq) + 3NaOH(aq) → Na3PO4(aq) + 3H2O(l)
mole of NaOH = 23.6 * 10 ⁻³L * 0.2M
= 0.00472mole
let x be the no of mole of H3PO4 required of 0.00472mole of NaOH
3 mole of NaOH required ------- 1 mole of H3PO4
0.00472mole of NaOH ----------x
cross multiply
3x = 0.0472
x = 0.00157mole
[H3PO4] = mole of H3PO4 / Vol. of H3PO4
= 0.00157mole / (10*10⁻³l)
= 0.157M
<h3>The concentration of unknown phosphoric acid is 0.157M</h3>
Answer:
I would recycle, reuse, and reduce the litter on this already hurt Earth.
Explanation:
Based on Le Chatelier's principle, when the equilibrium of a given reaction is disturbed due to some external factors like temperature, pressure or concentration, the equilibrium shifts in a direction to undo the effects of the change produced.
The given reaction is :-
CaCO3 (s) ↔ CaO (g) + CO2(g)
The forward reaction involves the formation of CaO and CO2 while the reverse involves formation of CaCO3.
If the concentration of the products CaO and CO2 is increased then the equilibrium will shift to a direction to counteract this increase. Hence, the products will tend to get used up and the reverse reaction will be favored.
Ans: B) the rate of reverse reaction will increase if the concentration of caO and CO2 is increased.
Answer:
Natural causes are unintentional.
Explanation:
An example would be a wildfire. This natural disaster spreads quickly, especially in forests where wood burns easily. Destroying forests through burning causes nutrients to get depleted, and organisms die.
