500kgh-1 of a 10% w/w solutionof a compoun X(OH)2 is to betreated using a 5% excess of 20% w/w solution of Na2CO3 toprecipitate the X as its carbonate according to the balancedreaction equation: X(OH)2 + Na2CO3 ------> XCO3 + 2NaOH All thesolid is filtered off but some solution remains with the solid suchthat the solution forms 4% w/w of the total mass removed. thefiltered liquid product is then neutralised with 2 molarhydrochloric acid according to the reactions NaCO3 + 2HCl ----->2NaCl + H2O + CO2 NaOH + HCl -----> NaCl + H2O Calculate: 1. theamount (kgh-1) of sodium carbonate solution required. 2. the amount(kgh-1) and composition (%w/w) of the solid product afterfiltration 3. the amount (kgh-1) and composition (%w/w) of thesolid product after filtration. 4. the amount of acid (in litresper hour) required for neutralisation data: Relative atomic mass ofX= 40, O=16, H=1, Na= 23, C= 12, Cl= 35.5
