1. Zine metal reacts with HCl(aq) as follows: Zn(s) + 2HCl(aq) â ZnCl2(aq) + H2(g) How many grams of ZnCl, can be obtained using a 5.00 g of zine metal? Ans. 2. A student prepared NaCO, by bubbling CO, through an aqueous solution of NaOH: 2NaOH(aq) + CO2(g) â Na2CO3(aq) +, H2O(T) Ir 15.0 g of NaOH was used, what mass of Na CO, is expected? Ans.: 3. Consider Q.3 above. If the student obtained 15.5 g of Na,CO, what is the % yield? Ans.:
