2C8H18 (1) + 2502 (g) --> 16CO2 (g) + 18H2O (g)
Makovka662 [10]

Answer:

One gallon of octane produces approximately 7000 L of carbon dioxide.

Note:

I believe that the mass of octane should have been given as 2661 g. However, I understand that your instructor probably gave you this problem, so I will use 4000 g for the approximate mass of one gallon of octane. You can rework the problem on your own, substituting the correct masses of octane if you wish.

Step1. You must first determine the number of moles that are in 4000 g of octane, using the molar mass of octane. Step 2. Then you must determine the number of moles of carbon dioxide that can be produced by that number of moles of octane, based on the mole ratio between octane and carbon dioxide in the balanced equation. Step 3. Then use the ideal gas law to determine the volume in liters of carbon dioxide that can be formed.

bekas [8.4K]

Answer:

3.4\times 10^3 eggs are produces are in a month.

Explanation:

Quantity of eggs produced by the chicken in a month = 284 dozens

1 dozen = 12 eggs

Number of eggs in a month:

284 dozens = 284\times 12 eggs =3,408 eggs\approx 3.4\times 10^3 eegs

3.4\times 10^3 eggs are produces are in a month.

Electronegativity is a measure of an atom’s affinity for electrons. Which of the following statements is true? Electronegativity
jekas [21]

Answer: Electronegativity increases as the size of an atom decrease.

Explanation: Electronegativity is the measure of the ability of an atom in a bond to attract electrons to itself.

Electronegativity increases across a period and decreases down a group.

Towards the left of the table, valence shells are less than half full, so these atoms (metals) tend

to lose electrons and have low electronegativity. Towards the right of the table, valence shells are more than half full, so these atoms (nonmetals) tend to gain electrons and have high electronegativity.

Down a group, the number of energy levels (n) increases, and so does the distance between the nucleus and the outermost orbital. The increased distance and the increased shielding weaken the nuclear attraction, and so an atom can’t attract electrons as strongly.
