5. according to the equation c3h8 + 502
3co2 + 4h20, when 02 is in excess, how many grams of
carbon dioxide are produced from the combustion of 250. g of ethane, c3h8?
produced from the combustion of 250 g of ethane

Explanation:

We will need a chemical equation with masses and molar masses, so, let's gather all the information in one place.

Mᵣ:    44.10                44.01

        C₃H₈ + 5O₂ ⟶ 3CO₂ + 4H₂O

m/g:  250.

(a) Moles of C₃H₈

(b) Moles of CO₂

(c) Mass of CO₂

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
