If 20 kg of calcium carbonate was reacted with excess sodium chloride in the following reaction (2NaCl+CaCo3-->Na2Co3+CaCl2) what is the maximum mass of sodium carbonate that could be made?

1)Always write out the reaction first; 2NaCl+CaCo3-->Na2Co3+CaCl2 2)Now underneath calculate the Relative Formula Mass using a periodic table for each of the compounds. CaCo3=100/ Na2Co3=106 3)Now always ...

Explain the trend in atomic radii from Lithium to Fluorine?

As we go from Li to F, atomic radius of the atoms will DECREASE. This is due to increased nuclear charge (number of protons within each atom). Although the number of electrons also increases, each additional...
