Stopper the flask loosely. Zinc with many pores so that it reacts faster. Therefore the electrons in $\\ce{ZnCl2}$ are able to jump this gap by absorbing certain radiation, when this radiation is absorbed all the radiations except these are reflected and can be seen as complimentary color which in this case happens to be black. For the best answers, search on this site https://shorturl.im/UW3aH, let say we have 100g of product A. In the initial description, you were told that zinc was a metal, hydrochloric acid and zinc chloride were in aqueous solutions and hydrogen was a gas. When the Zinc is added to the acid, the zinc dissolves and reacts with the acid, forming hydrogen gas and the salt Zinc Chloride. which will give off (99*10)/100= 9.9 g purity powder 9.9gZnO * (1mol ZnO/81.4g ZnO)*(1mol Zn2+ /1mol ZnO)*(65.4g/mol Zn)=7.954g Zn The mass of Zn we need is 7.954g The mass of ZnCl2 we need is: 7.954gZn *(1mol Zn/65.4g)*(1molZnCl2 / 1molZn)*(136.4gZnCl2 / 1 molZnCl2)= 16.589 g The zinc chloride available is a 98% purity product, thus we actually need (98*16.589 g)/100=16.267g ZnCl2 Since as the begining we assume that there is 100g product A; therefore, New percentage of ZnCl2 in product is( 16.267g/100g )*100 =16.267% The answer: Product A will contain 16% ZnCl2 instead of 10% ZnO in oder to maintain the same percentage of Zn.
