# Rel Analysis: LR of precipitation

SATCHM-A3GNV4

Use the following equation to answer the relationship analysis question that follows.

$CaCl_2(aq) + Na_2CO_3(aq) → CaCO_3(s) + 2NaCl(aq)$

I. 2.50 g of $CaCl_2$ is fully dissolved in a beaker of water and 2.50 g of $Na_2CO_3$ is fully dissolved in water in a second beaker. The two solutions are mixed to form a $CaCO_3$ precipitate and aqueous $NaCl$. $Na_2CO_3$ will be the limiting reactant in this experiment.

BECAUSE

II. Sodium carbonate has a molar mass which is less than the molar mass of calcium chloride.

A

Statement I is true, Statement II is true

B

Statement I is true, Statement II is false

C

Statement I is false, Statement II is true

D

Statement I is false, Statement II is false

E

Statement I is true, Statement II is true and is a correct explanation of the phenomena described in I
