Study the Lewis dot diagram for nitrogen. Explain what is correct and what is incorrect about the diagram. Use details to suppor
Verdich [7]

Answer:

The Lewis dot diagram is supposed to have dots on each side. What's incorrect is that there isn't a dot on the bottom, only the left and right side and the top. What's correct about this is that there are 5 outer valence electrons, and they correctly put 5 dots, even though they're in the wrong place.

If 15 grams of Carbon dioxide is produced in a chemical reaction, how many grams of Carbon must be consumed in the reaction if w
Nata [24]

4.1g

Explanation:

Given parameters:

Mass of carbon dioxide = 15g

Mass of oxygen gas = 11g

Unknown:

Mass of carbon consumed = ?

Solution:

   Equation of the reaction:

                                              C +  O₂   →   CO₂

    To solve this problem from the balanced equation,  we have to use the amount of product formed and work to Carbon. This is because, we are sure of the amount of carbon dioxide formed but the amount of the given oxygen gas used is not precise.

  Number of moles of CO₂ = \frac{mass}{molar mass}

Molar mass of CO₂ = 12 + (16 x2) = 44g/mol

   Number of moles of CO₂ = \frac{15}{44} = 0.34mole

From the equation of the reaction;

              1 mole of CO₂  is produced from 1 mole of C

           0.34mole of CO₂  will produce 0.34mole of C

Mass of carbon reacting = number of moles x molar mass = 0.34 x 12 = 4.1g
