Answer:
the answer to your question is A
Quantitative observations include numerical data. Ex: 32 degrees, 10 inches, etc.
Answer: the reaction rate of the forward reaction increases (although it is not among the options shown).
Explanation:
1) The equation given is:
CO (g) + Cl₂ (g) ⇄ COCl₂ (g)
2) The forward reaction is:
CO (g) + Cl₂ (g) → COCl₂ (g)
3) The stoichiometry is 1 mole + 1 mole → 1 mole
4) Analysis and conclusion:
The effect of change in the conditions of an equilibrium is foreseen using Le Chatelier's principle.
Le Chatelier's principle states that a system in equilibrium will act trying to compensate the distress applied to the system.
In this case, the distress is increase in pressure.
To compensate the increase in pressure the system must act by reducing the number of moles in the system. Since the forward reaction implies the conversion of two moles of reagents into one mole of product, the more the forward reaction progress the less the number of moles will be present in the system and so the more the compensation of the increase in pressure. So the forward raction is favored by the increase in pressure.
Favoring the forwar reaction means that its rate will incrase,
Answer:
7.90×10²¹ formula units
Explanation:
From the question given above, the following data were obtained:
Mass of Cu(NO₃)₂ = 2.46 g
Formula units of Cu(NO₃)₂ =?
From Avogadro's hypothesis,
1 mole of Cu(NO₃)₂ = 6.02×10²³ formula units
Next, we shall determine the mass of 1 mole of Cu(NO₃)₂. This can be obtained as follow:
1 mole of Cu(NO₃)₂ = 63.5 + 2[14 + (3×16)]
= 63.5 + 2[14 + 48]
= 63.5 + 2[62]
= 63.5 + 124
= 187.5 g
Thus,
187.5 g of Cu(NO₃)₂ = 6.02×10²³ formula units
Finally, we shall determine the formula units contained in 2.46 g of Cu(NO₃)₂. This can be obtained as follow:
187.5 g of Cu(NO₃)₂ = 6.02×10²³ formula units.
Therefore,
2.46 g of Cu(NO₃)₂ =
(2.46 × 6.02×10²³)/187.5
= 7.90×10²¹ formula units
Thus, 2.46 g of Cu(NO₃)₂ contains 7.90×10²¹ formula units
Answer:
- <em>The partial pressure of the oxygen gas is </em><u>96.00 KPa</u>
Explanation:
The law of partial pressures states that, in a mixture of gases, the total pressure of the mixture is equal to the sum of the individual pressures of each gas, as if each gas were alone in the mixture.
So:
- Total pressure = ∑ individual pressures
- Total pressure = Partial pressure of the water + Partial pressure of oxygen
- 98.67 KPa = 2.67 KPa + Partial pressure of oxygen
- Partial pressure of oxygen = 98.67 KPa - 2.67 KPa
- Partial pressure of oxygen = 96.00 KPa ← answer
