C. Cesium because ionization energy increases as you move from left to right across a period and from down up a column of the periodic table, making a diagonal pattern from the bottom left corner to the top right of the periodic table.

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

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.
