Ihave a test soon! the reaction between the limestone and hydrochloric acid produces carbon dioxide as shown in the reaction.
caco3(s) + 2hcl(aq) + co2(g) + cacl2(aq) + h2o(l)
how many grams of co2 can be made by reacting 112 g of caco3 with 112 g of hci?
how many grams of hcl are left over?

An electrons position cannot be known precisely only it's probability of being in a certain location can be known

Acamcorder has a power rating of 17 watts. if the output voltage from its battery is 7 volts, what current does it use?units:

An atom of lithium (li) and an atom of chlorine (cl) engage in a chemical reaction. which correctly describes the structure of the resulting chemical compound? hint: consider the class of each element. the chemical compound will have a network structure. the chemical compound will have triple bonds. the chemical compound will have a ball-and-stick structure. the chemical compound will have double bonds.
