Calculate the number of pounds of CO2CO2 released into the atmosphere when a 22.0 gallon22.0 gallon tank of gasoline is burned i

Gnesinka [82]

Answer:

391.28771 pounds of carbon-dioxide was released into the atmosphere when 22.0 gallon tank of gasoline is burned in an automobile engine.

Explanation:

Density of the gasoline ,d= 0.692 g/mL

Volume of gasoline in an tanks,V = 22.0 gallons = 83,279.02 mL

Let mass of the gasoline be M

$Density= \frac{Mass}{Volume}$

M = V × d = 83,279.02 mL × 0.692 g/mL=57,629.081 g

Given that gasoline is primarily octane.

$2C_8H_{18}+25O_2\rightarrow 16CO_2+18H_2O$

Mass of octane burnt in the tank = M = 57,629.081 g

Moles of octane = $\frac{57,629.081 g}{114.08g/mol}=505.1637 mol$

According to reaction, 2 moles of octane gives 16 moles of carbon-dioxide.

Then 505.1637 mol of octane will give:

$\frac{16}{2}\times 505.1637 mol=4,041.3100 mol$ of carbon-dioxide

Mass of 4,041.3100 mol of carbon-dioxide:

4,041.3100 mol × 44.01 g/mol = 177,858.05 g

Mass of carbon-dioxide produced in pounds = 391.28771 pounds

391.28771 pounds of carbon-dioxide was released into the atmosphere when 22.0 gallon tank of gasoline is burned in an automobile engine.

Choose the correct answer. The difference between the mass number of an isotope and its atomic number is (a) directly related to

kicyunya [14]

Answer : The correct answer is, (c) the number of neutrons

Explanation :

Isotope : It is defined as the element that have the same number of protons but have the different number of neutrons of each of the atom.

Atomic number is defined as the number of protons or number of electrons.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and number of neutrons.

Number of neutrons = Mass number - Atomic number

For example : For Carbon - 13 isotope.

Mass number = 13

Atomic number = 6

Number of neutrons = Mass number - Atomic number

Number of neutrons = 13 - 6 = 7

Hence, the difference between the mass number of an isotope and its atomic number is the number of neutrons.

URGENT PLEASE HELP!!

Orlov [11]

Answer:

Liters per second is 0.2 LPS

Liters per hour is 720

Explanation:

Divide the litres by the time, than multiply the time of an hour (in seconds) and than multiply the lps by time of an hour in seconds.

Which of the following is a characteristic of an exothermic chemical reaction?

adelina 88 [10]

Answer:

The correct answer is The overall enthalpy of the system increases during the change.

Explanation:

Exothermic is type of chemical reaction that deals with the generation of energy in form of heat.Exothermic reactions are thermodynamically favorable because free energy change during exothermic reaction is highly negative.

Enthalpy is a state function which measures the heat content of the system.As there is a generation of heat from the reaction to the system in which the reaction is taking place,the heat content of the system increases which ultimately result in increasing the overall change of the enthalpy.

Does a precipitate form when a solution of sodium acetate and a solution of ammonium sulfate are mixed together?

e-lub [12.9K]

<h3><u>Answer</u>;</h3>

No, a precipitate does not form

<h3><u>Explanation</u>;</h3>

Precipitation involves mixing or combining solutions that contain soluble ionic compounds to form an insoluble ionic compound by a reaction.
Sodium acetate and ammonium sulfate are both soluble ionic compounds, which implies that they exist as ions in aqueous solution.
<em><u>When they combine they form NH4CH3COOH and sodium sulfate, Na2SO4, which are both soluble salts, as all salts of ammonium and sodium are soluble.</u></em>
<em><u>Both ammonium acetate and sodium sulfate are soluble because there are no anions that can form an insoluble solid with NH4+ and Na+ cations. </u></em>
