5 0

Answer:

329.7%

Explanation:

Percent Yield = Actual Yield/ Theoretical Yield x 100%

Percent Yield = 105.5g/32 x 100% = 329.69 ≈ 329.7 %

How many moles of carbon dioxide gas should be produced when 10.0 g of C2H6 are combusted at STP?
Finger [1]

Answer:

                    0.665 moles of CO₂

Explanation:

                     The balance chemical equation for the combustion of Ethane is as follow:

                            2 C₂H₆ + 7 O₂ → 4 CO₂ + 6 H₂O

Step 1: <u>Calculate moles of C₂H₆ as;</u>

                              Moles  =  Mass  /  M.Mass

Putting values,

                              Moles  =  10.0 g / 30.07 g/mol

                              Moles  =  0.3325 moles

Step 2: <u>Calculate Moles of CO₂ as;</u>

According to balance chemical equation,

                    2 moles of C₂H₆ produced  =  4 moles of CO₂

So,

             0.3325 moles of C₂H₆ will produce  =  X moles of CO₂

Solving for X,

                      X  =  0.3325 mol × 4 mol ÷ 2 mol

                      X = 0.665 moles of CO₂

In the wild, female and juvenile African elephants typically live in herds that vary in size, depending on the
uysha [10]

Herd behavior in elephants ensures that individuals are protected and the species is perpetuated.

<h3>What is her behavior?</h3>

It is a behavior that is characteristic of animals that form herds.

Herds generally refer to groups of animals that live or move together or both.

By protecting individual elephants that are weak or young from being preyed upon by lions and leopards, more members of the population survive.

When more members of the population survive, the species is perpetuated and the likelihood of going into extinction reduces.
