Question

1. in this experiment, you will be mixing aqueous solutions of sodium carbonate and calcium chloride to produce solid calcium carbonate. na₂co₃(aq) + cacl₂(aq) → 2 nacl(aq) + caco₃(s) 2 order the steps required to predict the volume (in ml) of 0.100 m sodium carbonate needed to produce 1.00 g of calcium carbonate. there is an excess of calcium chloride. step 1 choose match step 2 choose match step 3 choose match step 4 choose match choose match compute the volume of sodium carbonate solution required convert mass of calcium carbonate to moles of calcium carbonate compare moles of calcium carbonate to moles of sodium carbonate based on balanced equation to calculate moles of sodium carbonate required convert the volume of sodium carbonate solution required from liters to milliliters

Explanation:

Step1: Compute the moles of calcium carbonate

Use the formula \(n=\frac{m}{M}\), where \(m = 1.00\space g\) (mass of \(CaCO_3\)) and \(M = 100.09\space g/mol\) (molar mass of \(CaCO_3\)). So, \(n_{CaCO_3}=\frac{1.00\space g}{100.09\space g/mol}\)

Step2: Compare moles of calcium carbonate to moles of sodium carbonate

From the balanced equation \(Na_2CO_3(aq)+CaCl_2(aq)\to2NaCl(aq)+CaCO_3(s)\), the mole ratio of \(Na_2CO_3\) to \(CaCO_3\) is \(1:1\). So \(n_{Na_2CO_3}=n_{CaCO_3}\)

Step3: Convert moles of sodium carbonate to volume of sodium carbonate solution

Use the formula \(V=\frac{n}{C}\), where \(n = n_{Na_2CO_3}\) and \(C = 0.100\space M\) (concentration of \(Na_2CO_3\) solution). So \(V=\frac{n_{Na_2CO_3}}{0.100\space mol/L}\)

Step4: Convert the volume of sodium carbonate solution from liters to milliliters

Use the conversion factor \(1\space L = 1000\space mL\). So \(V(mL)=V(L)\times1000\)

Answer:

Step 1: Compute the mass of calcium carbonate to moles of calcium carbonate
Step 2: Compare moles of calcium carbonate to moles of sodium carbonate based on balanced equation to calculate moles of sodium carbonate required
Step 3: Convert moles of sodium carbonate to volume of sodium carbonate solution
Step 4: Convert the volume of sodium carbonate solution from liters to milliliters
