A student wanted to make 11.0 g of copper chloride. The equation for the reaction is:

CuCO3 + 2HCl → CuCl2 + H2O + CO2

Relative atomic masses, Ar: H = 1; C = 12; O = 16; Cl = 35.5; Cu = 63.5
Calculate the mass of copper carbonate the student should react with dilute
hydrochloric acid to make 11.0 g of copper chloride.

a.   mass number from atomic number

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
