how many liters of carbon dioxide gas are formed at stp when 3.829 x 10^25 representative particles of c8h18 are reacted in an excess of oxygen gas at stp are fully reacted
Answers
The carbon dioxide gas that will be formed at STP is , 1.38 liters after the application of Ideal Gas law.
What is Combustion?A combustion reaction is an exothermic chemical process involving two or more substances that typically produces heat, energy, and light (flame). The substance that is burned determines the reaction's byproducts.
The balanced equation for the combustion of octane C₈H₁₈ with oxygen gas (O₂) is:
C₈H₁₈ + 12.5 O₂ → 8CO₂ + 9H₂O To calculate the number of liters of carbon dioxide gas produced at STP, we need to use the Ideal Gas Law, PV = nRT.
Here, we know the following: P = 1 atm (STP) T = 273 K (STP) ,R = 0.0821 Latm/mol K
The number of moles of C₈H₁₈ reacted is (3.829 x 1025 representative particles) / (6.022 x 1023 representative particles/mol) = 6.38 x 10-2 mol
The number of moles of CO₂ produced is 8 mol CO₂ per mol C₈H₁₈ reacted ,so we can find n,(the number of moles of CO₂ produced) :
n = 8 x 6.38 x 10-2 mol = 0.05104 mol
Finally, we can use the Ideal Gas Law to find the volume of CO₂ produced at STP:
V = nRT / P
So, V = 0.05104 mol x 0.0821 Latm/molK x 273 K / 1 atm = 1.38 L
Therefore, 1.38 liters of carbon dioxide gas are formed at STP when 3.829 x 1025 representative particles of C₈H₁₈ are reacted in an excess of oxygen gas at STP are fully reacted.

No, it does not pass the "fat pencil" test. Therefore, a normal distribution is not a reasonable model. Option B is the correct answer.
The "fat pencil" test is a quick visual check to determine if a dataset can be reasonably approximated by a normal distribution. In this case, the pH readings of wastewater show a significant deviation from a normal distribution. The presence of several low pH values (1.0) and a few high pH values (10.0, 10.5, 11.4) indicate a non-normal distribution with skewness and potential outliers. Therefore, it is not reasonable to model these data using a normal distribution.

for the following endothermic reversible reaction at equilibrium, how will removing no(g) affect it? 4no(g) 6h2o(g) rightwards harpoon over leftwards harpoon with blank on top 4nh3(g) 5o2(g)
Answers
Removing NO(g) from the equilibrium of the endothermic reversible reaction will shift the equilibrium to the left, resulting in an increase in the production of NO(g) and H₂O(g) while consuming NH₃(g) and O₂(g).
For the endothermic reversible reaction at equilibrium, removing NO(g) will affect it as follows:
Reaction: 4NO(g) + 6H₂O(g) ⇌ 4NH₃(g) + 5O₂(g)
Since this is an endothermic reaction, it means that the reaction absorbs heat from its surroundings when it proceeds in the forward direction (left to right). At equilibrium, the rates of the forward and reverse reactions are equal.
When you remove NO(g) from the system, you are essentially decreasing the concentration of NO(g) in the reaction mixture. According to Le Chatelier's principle, the system will counteract this change by shifting the position of equilibrium to restore the balance.
In this case, the equilibrium will shift to the left to replenish the NO(g) that was removed. This means the reaction will proceed more in the reverse direction (right to left), producing more NO(g) and H₂O(g) while consuming NH₃(g) and O₂(g).
In summary, removing NO(g) from the endothermic reversible reaction at equilibrium will cause the reaction to shift to the left, producing more NO(g) and H₂O(g) while consuming NH₃(g) and O₂(g).

If 23.2 g of a given gas occupies a volume of 93.2 L at a particular temperature and pressure, what
mass of the gas occupies a volume of 10.4 L under the same conditions?
Answers
Answer:
2.59g
Explanation:
Using Avagadro's law equation as follows:
V1/n1 = V2/n2
Where;
V1 = initial volume (litres)
V2 = final volume (litres)
n1 = first amount of gas in grams
n2 = second amount of gas in grams
According to the information provided in this question, v1 = 93.2L, v2 = 10.4L, n1 = 23.2 g, n2 = ?
Using V1/n1 = V2/n2
93.2/23.2 = 10.4/n2
Cross multiply
93.2 × n2 = 23.2 × 10.4
93.2n2 = 241.28
n2 = 241.28/93.2
n2 = 2.588
n2 = 2.59g
The mass of the gas is 2.59g that occupies a volume of 10.4 L under the same conditions.
Avogadro's law equation:V₁/n₁ = V₂/n₂
Where
V₁ = initial volume (litres)
V₂ = final volume (litres)
n₁ = first amount of gas in grams
n₂ = second amount of gas in grams
Given:
V₁ = 93.2L,
V₂ = 10.4L,
n₁ = 23.2 g,
To find:
n₂ = ?
On substituting the values:
93.2/23.2 = 10.4/n₂
93.2 * n₂ = 23.2 * 10.4
93.2* n₂ = 241.28
n₂ = 241.28/93.2
n₂ = 2.588
n₂ = 2.59g
Thus, the mass of the gas is 2.59g.
