- For a 50ml beaker, 0.4532g of pure iron III oxide was weighed, to which 1 ml of a concentrated hydrochloric acid solution was added and then 20 ml of deionized water was added to the beaker. After mixing, the resulting solution was transferred to a 50.00 ml flask and the volume was made up with deionized water. Then 15ml of this solution into a second beaker to which 10ml of an iron iii chloride solution of 0.200 M concentration was added. Calculate the final concentration of the iron iii cation solution expressed in mol/L and in g/L, considering that the volumes are additive.Please Help me complete part d, e and f of question 4.If the following equation was balanced, the coefficient of water would be: Fe + H2O → Fe2O3 + H2
- what is the reaction of iron plus caustic soda plus calcium carbonate?During one of the washes, 10 mL of dilute NaOH was added to the product mixture. Select the statements that are true. NaOH is neither acidic nor basic, but neutral, which is characteristic of sodium compounds. The purpose of the NaOH is to neutralize H,SO, that is present in the mixture in an acid-base reaction. The purpose of the NaOH is to absorb water in the product mixture.Can you separate Calcium carbonate from sand and water through the process of precipitation, if yes, what will happen to sand?
