Answer: 8 moles
Explanation:
C3H8(g) + 5O2(g) ---> 3CO2(g) + 4H2O(g)
The balanced equation above shows the combustion of propane, C3H8 (for x is 3; y is 8) in oxygen, O2 to yield carbon dioxide, CO2 and water, H2O
The mole ratio on combustion are as follows:
5 moles of O2 react to produce 3 moles of CO2
Z mole of O2 react to produce 4.8 moles of CO2
To get the value of Z, cross multiply
4.8 moles x 5 mole = 3 mole x Z
24 = 3Z
Divide both sides by 3
24/3 = 3Z/3
8 = Z
Thus, in the combustion of propane, 8 moles of oxygen (O2) are needed to react to produce 4.8 moles of carbon dioxide (CO2)
Answer:
(4) The navy needed a faster way to move ships between the Atlantic and Pacific Oceans.
Explanation:
The Panama Canal was an artificial eighty-two (82) kilometers water-way that connects the Atlantic Ocean with the Pacific Ocean in Panama and it enhanced maritime trades.
The construction of the Panama Canal became more important to the United States after the Spanish-American War because the navy needed a faster way to move ships
between the Atlantic and Pacific Oceans.
