Answer: In balancing any chemical equations, the number of atoms of each elements on the reactant side is equals to the number of atoms of the elements on the product side.
Step-by-step explanation:
Balanced Chemical equations are those equations that has the equal number of atoms of elements on both the reactants and the product sides. To ensure that the chemical equations are correctly balanced the following steps should be observed.
--> identify the elements on the reactant side and on the product side
--> identify the number of atoms of each elements.
--> multiply the number of atoms with the number that will give you a coefficient that will make both the reactant and product sides equal.
--> place the new numbers infront of the elements or compounds.
--> A final check is done to know if the equation is balanced.
From the above steps, the balanced equation of the above questions are listed below:
1.) AlBr3 + 3K ---> 3KBr + Al
2.) FeO + PdF2 --> FeF2 + PdO
3.) P4 + 6Br2 --> 4PBr3
4.) 2LiCl + Br2 --> 2LiBr + Cl2
5.) PbBr2 + 2HCl --> 2HBr + PbCl2
6.) 2CoBr3 + 3CaSO4 --> 3CaBr2 + Co2(SO4)3
7.) 2Na3P + 3CaF2 --> 6NaF + Ca3P2
8.) 2Mn + 6HI --> 3H2 + 2MnI3
9.) Li3PO4 + 3NaBr --> Na3PO4 + 3LiBr
10.) CaF2 + Li2SO4 --> CaSO4 + 2LiF
11.) 2HBr + Mg(OH)2 --> MgBr2 + 2H2O
12.) 2LiNO3 + CaBr2 --> Ca(NO3)2 + 2LiBr
13.) AgNO3 + Li --> LiNO3 +Ag
14.) Si(OH)4 + 4NaBr --> SiBr4 + 4NaOH
15.) 2NaCN + CuCO3 --> Na2CO3 + Cu(CN)2
16.) 2NH3 + H2SO4 --> (NH4)2SO4
