200 grams of marble chips are dropped into 100 g of hydrochloric acid. How much chips will remain undissolved? What weight of anhydrous calcium chloride and what weight of carbon dioxide gas could be obtained from it?

The balanced equation for the chemical change is

Since marble chips remain undissolved, HCl is a limiting reagent.
73 g of HCl react with `CaCO_3 = 100 g `
100 g of HCl will react with `CaCO_3`
`=(100)/(73 ) xx 100 = 136 .986 g `
Weight of chips undissolved = 200 - 136.986 = 63.014 g
73 g of HCl produce `CaCl_2` = 111 g
100 g of HCI will produce `CaCl_2 =(111)/(73)xx 100 = 152.05 g`
73 g of HCI produce `CO_2 = 44 `g
100 g of HCl will produce `CO_2 =(44)/(73) xx 100 = 60.27` g
