liquid octane reacts with gaseous oxygen gas to produce gaseous carbon dioxide and gaseous water . what is the theoretical yield of carbon dioxide formed from the reaction of of octane and of oxygen gas? be sure your answer has the correct number of significant digits in it.
Answers
The theoretical yield of carbon dioxide formed from the reaction of octane and oxygen gas is 24.70g
We'll start by creating a balanced equation to describe how octane reacts with oxygen to create CO₂ and water. Below is an example to help:
25O₂ + 2CH₃(CH₂)6CH₃----------> 16CO₂ + 18H₂O
Let's next take the octane and oxygen reaction masses from the balanced equation. Below is an example to help:
CH₃ Molar Mass (CH₃)
6CH₃ = 12 + (3x1) + 6[(12 + (2x1)] + 12 + (3x1)
= 12 + 3 + 6(14) + 12 + 3
= 12 + 3 + 84 + 12 + 3
= 114g/mol
From the balanced equation, the mass of CH₃(CH₂)6CH₃ that reacted was equal to 2 x 114 grams.
O₂ Molar Mass = 16 x 2 = 32 g/mol
The balanced equation yielded the reaction mass of O₂ as
25 x 32 = 800g.
Let's next identify the limiting reactant among the reactants. Below is an example to help:
From the above-balanced equation, 800g of oxygen was needed for full combustion with 228g of octane.
As a result, 28.07g of oxygen will be needed for 8g of octane, or (8 x 800)/228.
Since the quantity of oxygen required (28.07g) is less than what was provided (i.e. 38.9g) from the inquiry, it is obvious from the calculations done above that oxygen is the surplus reactant. Octane is the limiting reactant as a result.
Now, as shown, we can determine the theoretical CO₂ yield:
The reaction's equation is provided below:
25O₂ + 2CH₃(CH₂)6CH₃ = 16CO₂ + 18H₂O
Molar CO₂ mass equals
12 + (2x16) = 12 + 32 = 44g/mol
The balanced equation yields a mass of CO₂ equal to
16x44 = 704g.
From the above-balanced equation,
704g of CO₂ was created from 228g of octane.
Thus, 8g of octane will result in = (8 x 704)/228 = 24.70g of CO₂ being produced.
Therefore, 24.70g is the theoretical CO₂ yield.

Write a net ionic equation to show that ethylamine, C2H5NH2 behaves as a Bronsted-Lowry base in water. (For organic molecules enter elements in order they are given in the question.) Write a net ionic equation to show that benzoic acid, C6H5COOH, behaves as a Bronsted-Lowry acid in water.
Answers
The net ionic equation for the behavior of ethylamine (C₂H₅NH₂) as a Bronsted-Lowry base in water is:
C₂H₅NH₂ + H₂O → C₂H₅NH₃⁺ + OH⁻
The net ionic equation for the behavior of benzoic acid (C₆H₅COOH) as a Bronsted-Lowry acid in water is:
C₆H₅COOH + H₂O → C₆H₅COO⁻ + H₃O⁺
In water, ethylamine (C₂H₅NH₂) can act as a Bronsted-Lowry base by accepting a proton (H⁺) from water. The reaction can be represented by the net ionic equation: C₂H₅NH₂ + H₂O → C₂H₅NH₃⁺ + OH⁻. In this equation, ethylamine (C₂H₅NH₂) accepts a proton from water (H₂O) to form the ethylammonium ion (C₂H₅NH₃⁺) and hydroxide ion (OH⁻). This shows the base behavior of ethylamine as it accepts a proton.
On the other hand, benzoic acid (C₆H₅COOH) can act as a Bronsted-Lowry acid in water by donating a proton (H⁺) to water. The reaction can be represented by the net ionic equation: C₆H₅COOH + H₂O → C₆H₅COO⁻ + H₃O⁺.
In this equation, benzoic acid (C₆H₅COOH) donates a proton to water (H₂O) to form the benzoate ion (C₆H₅COO⁻) and hydronium ion (H₃O⁺). This demonstrates the acid behavior of benzoic acid as it donates a proton.

An electric device delivers a current of 5.0 A to a device. How many electrons flow through
this device in 10 s? (e = 1.60 × 10-19 C)
A) 0.20
B) 20
C) 2.0
D) 3.1 x 10^20
E) 31 x 10^20
Answers
Therefore, the answer is D) 3.1 × 10^20. This means that 3.1 × 10^20 electrons flow through the device in 10 seconds.
To calculate the number of electrons that flow through the device in 10 seconds, we need to use the formula:
number of electrons = (current × time) / charge of one electron
We are given the current, which is 5.0 A, and the time, which is 10 seconds. The charge of one electron is e = 1.60 × 10-19 C. Plugging these values into the formula, we get:
number of electrons = (5.0 A × 10 s) / (1.60 × 10-19 C)
Simplifying this expression, we get:
number of electrons = (5.0 × 10) / (1.60 × 10-19)
number of electrons = 3.125 × 10^20
It is important to note that this is a very large number of electrons, which highlights the fact that even small currents can involve a large number of electrons.

C Volume --> Mass --> Moles
D Moles --> Mass --> Volume
Answers
Answer: 1. 20.0 grams
2. 0.272 moles
3. B) Mass --> Moles --> Volume
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number \(6.023\times 10^{23}\) of particles.
To calculate the number of moles, we use the equation:
\(\text{Number of moles}=\frac{\text{Given molecules}}{\text{Avogadros number}}\) or
\(\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}\) or
Putting in the values we get:
1. \(\text{Number of moles of} Cl_2=\frac{1.7\times 10^{23}}{6.023\times 10^{23}}=0.282moles\)
Mass of \(Cl_2=moles\times {\text {Molar mass}}=0.282mol\times 71g/mol=20.0g\)
2. \(\text{Number of moles of NaCl}=\frac{3.28\times 10^{23}}{2\times 6.023\times 10^{23}}=0.272moles\)
3. \(\text{Number of moles of water}=\frac{26g}{18g/mol}=1.44moles\)
Volume of water =\(moles\times {\text {Molar volume}}=1.44mol\times 22.4L/mol=32.4L\)

one gram of sugar provides 4.0 calories how many calories wil you get by drinking one can of 330 ml of cola
Answers
By drinking one can of 330 ml cola, you will get approximately 140 calories from the sugar content
To determine the number of calories you will get by drinking one can of 330 ml cola, you need to follow these steps:
1. Identify the amount of sugar in one can of 330 ml cola: The sugar content of cola varies depending on the brand, but on average, it contains about 10.6 grams of sugar per 100 ml. To find the sugar content in a 330 ml can, you can calculate as follows:
(10.6 grams of sugar/100 ml) * 330 ml = 34.98 grams of sugar
2. Calculate the calories provided by the sugar in the can: As the student question mentions, one gram of sugar provides 4.0 calories. Now, multiply the amount of sugar in the can by the calories provided by each gram of sugar:
34.98 grams of sugar * 4.0 calories/gram = 139.92 calories
3. Round the number of calories: In this case, you can round the number of calories to the nearest whole number for simplicity:
139.92 calories ≈ 140 calories
So, by drinking one can of 330 ml cola, you will get approximately 140 calories from the sugar content. Keep in mind that this number may vary depending on the specific brand of cola and the sugar content in their recipe. Additionally, it's essential to consider the potential health impacts of consuming sugary drinks, as excessive sugar intake can contribute to health problems like obesity, diabetes, and tooth decay.

there are gas molecules that move slower than the average. the average speed of gas molecules decreases with decreasing temperature. the average kinetic energy of gas molecules decreases with decreasing temperature. all the gas molecules in a sample cannot have the same kinetic energy. the kinetic energy of a molecule cannot determine its speed.
Answers
A set of particles (atoms or molecules) that are constantly moving at random makes up a gas sample, according to the kinetic energy of a molecular theory.
Moreover, these gas particles' average kinetic energy solely depends on the temperature of the gas. With an increase in gas temperature, the average kinetic energy rises (this tells that the fifth statement is true). Despite the fact that certain gas molecules will always be travelling more quickly than others, the gas can still be represented by its average kinetic energy. Because kinetic energy is proportional to the square of the speed, the second claim—that the average speed of gas molecules rises with rising temperature—is derived from this.

A sealed balloon is filled with 1.00L of Helium at 23 C and at a pressure of 4.45atm . The balloon rises to a point in the atmosphere where the pressure is 0.289 atm and the temperature is - 31 C . What is the new volume , in liters ?
Answers
Answer:
We can use the combined gas law to solve this problem:
(P1V1)/T1 = (P2V2)/T2
where P1, V1, and T1 are the initial pressure, volume, and temperature, respectively, and P2 and T2 are the final pressure and temperature, respectively. We can solve for V2, the final volume:
V2 = (P1V1T2)/(P2T1)
Plugging in the values we have:
V2 = (4.45 atm * 1.00 L * 242 K) / (0.289 atm * 296 K)
V2 = 132.5 L
Therefore, the new volume of the balloon is approximately 132.5 liters.

The error is a means of expressing the accuracy of a measurement. The percentage error is . The correct option is D.
What is error?When there occurs a difference between the value of a physical measurement obtained for a person and its true or most probable value, we say that the measurement includes error.
The absolute error is the difference between the observed value and the true or most probable value of the quantity measured.
The percentage error or relative error is the ratio of the error to the true or most probable value. The relative error is more useful than absolute error. It is given as:
ER = x₀ - xₙ / xₙ
x₀ - observed value
