Propane reacts with 3.15moles of oxygen how much propane reacts with oxygen​
Inessa [10]

27.7g

Explanation:

Given parameters:

Number of moles of oxygen = 3.15moles

Unknown:

Mass of reacting propane = ?

Solution:

   Equation of the reaction:

                   C₃H₈ + 5O₂   →    3CO₂    +     4H₂O

 We work from the known to the unknown parameters.

The known in this expression is the number of moles of oxygen.

   In the reaction:

                   5 moles of oxygen gas reacts with 1 mole of propane

  3.15 mole of oxgen gas will react with    \frac{3.15}{5} = 0.63moles

Number of moles of reacting propane gas is 0.63moles

To find the mass;

         mass = number of moles x molar mass = 0.63 x molar mass

molar mass of propane = (3 x 12) + (8x1) = 44g/mol

         mass of propane = 0.63 x 44 = 27.7g

nata0808 [166]

Answer: The correct answer is C) carbon dioxide; calcium.

Explanation:

Carbonated soft drinks contain big concentrations of carbon dioxide, which is the bubbles that we see and feel. When these drinks are included regurly in the diet, the carbon dioxide levels are increased; and according to several studies high carbon dioxide values are related with bone loss.

Additionally, calcium is known for being an important nutrient for both formation and maintenance of bones, so inadequate intake of calcium in the diet results in a bone loss.
