If 7.4 moles of carbon dioxide is produced in this reaction, how many moles of oxygen gas would be needed?

Nimfa-mama [501]

Answer:

11.6 mol O₂

Explanation:

C₇H₁₆ + 11 O₂ → 7 CO₂ + 8 H₂O

In order to solve this problem we need to convert moles of carbon dioxide (CO₂) into moles of oxygen gas (O₂). To do so we'll use a conversion factor containing the stoichiometric coefficients of the balanced reaction:

7.4 mol CO₂ * $\frac{11molO_2}{7molCO_2}$ = 11.6 mol O₂

What effects do winds patterns have on climate

Nezavi [6.7K]

Prevailing winds bring air from one type of climate to another. For example, warm winds that travel over water tend to collect moisture as they travel; the water vapor in the air will condense as it moves into colder climates, which is why temperate coastal areas often receive heavy rainfall.
