Lead nitrate can be decomposed by heating. what is the percent yield of the decomposition reaction if 9.9 g of pb(no3)2are heated to give 5.5 g of pbo? 2pb(no3)2( s) → 2pbo( s) + 4no2( g) + o2( g)

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
