Please help!! 20 points!! Posted this previously and forgot to change it to 20 points but it is now
spayn [35]

Answer:

0.571 mol

Explanation:

Given data:

Number of moles of NaHCO₃ = 0.571 mol

Number of moles of CO₂ produced = ?

Solution:

Chemical equation:

NaHCO₃ + C₃H₆O₃   →     CO₂  + C₃H₅NaO₃ + H₂O

Now we will compare the moles of CO₂ with NaHCO₃ from balance chemical equation.

                             NaHCO₃          :            CO₂

                                    1                :               1

                                 0.571            :            0.571

So number of moles of CO₂  produced are 0.571.

What is the density of a sample of the alloy pewter, (a mixture of tin and copper or lead) if a 7.11 cm3 sample has a mass of 53
xxTIMURxx [149]

Answer:

<h3>The answer is 7.47 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 53.137 g

volume = 7.11 cm³

We have

density =  \frac{53.137}{7.11}  \\  = 7.473558368...

We have the final answer as

<h3>7.47 g/cm³</h3>

Hope this helps you
