A reaction between a solution sodium carbonate is mixed with a solution of calcium nitrate to cause a precipitation reaction. If 276.3 mL of 0.723 mol/L sodium carbonate is added to 834.7 mL of 1.260 mol/L calcium nitrate, what is the mass (in g) of precipitate that forms? Provide your answer to two decimals.

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
