An experiment calls for 50 mL of a 0.5 M aqueous solution of sodium hydrogen carbonate. Describe how you would make up such a solution?

I know that volume or weight over volume percent gives you the concentration. So I think that the slope signifies the concentration?

So im doing this equation in chemistry CH4 + Cl2-CCl+HCl and it says there are 5 Cl but how do i know if there is 5 Cl

can I know values for all the elements in Ionization enthalpy ?
