How many moles of lead(II) chloride will be formed from a reaction between 6.5 g PbO and 3.2 g HCl? Solution: The reaction between PbO and HCl is: PbO + 2 HCl → PbCl2+ H2O From the reaction it is clear that 1 mole PbO reacts with 2 mole of HCl. Now, moles of PbO = Given
In this post, we will discuss about Dalton’s Atomic Theory. Dalton based his theory on two laws: the law of conservation of mass and the law of constant composition. The law of conservation of mass says that matter is not created or destroyed in a closed system. That means if we have a chemical reaction, the amount
