Is an excellent example of a series of random letters and numbers that somehow manage to fail utterly at being a question.
Mg(s) + 2HCl(aq) --> MgCl2(aq) + H2(g)
This is an example of a single replacement (displacement) reaction.
MgBr2 + Cl2 --> MgCl2 + Br2
This is an example of a halogen replacement/displacement reaction, which is a type of single replacement/displacement reaction.
The chemical formula of magnesium chloride is MgCl2.
no reaction
Chemical formula of:tin is Snsalt is Na+aq and Cl-aqwater is H2OThere is no equation because there is no reaction!
NaCl------------>Na+ + Cl-
The chemical equation is:Na + OH- + H+ + Cl- = Na+ + Cl- + H2O(l)
The arrow is always pointing to it. If you know the reaction is ionic, break up the ions in the reactants. Example: NaOH reacts with HCl. Ions in NaOH are Na+ and OH-, in HCl, it is H+ and Cl-. Mix and match the ions and you get a Na+ with a Cl- giving NaCl (salt) and H+ with OH- giving HOH, i.e. H2O (water).
no reaction
AlBr2 + Cl = AlCl + Br2
Chemical formula of:tin is Snsalt is Na+aq and Cl-aqwater is H2OThere is no equation because there is no reaction!
Sodium chloride is dissociated in water: NaCl---------------------Na+ + Cl-
The balanced equation would be: MgBr2 + Cl2 ----> MgCl2 + Br2 Note: The equation is already balanced, both Cl and Br are diatomic elements they cannot exist alone as Cl or Br, they must be Cl2 and Br2. Also, this reaction happens because Cl is more active than Br, so it can displace it (halides activity series).
It is:2Na(s) + Cl2(g) → 2NaCl(s)(But remember in exams you should know this kind of method) Peace out, add me on BBM its:12b6a7d9
This reaction is:CH3CH2CH2CH2NH2 + HCl -------------->[CH3CH2CH2CH2NH3]Cl
capital c small l
The balanced equation would beNa + Cl -> NaCl Basically this reaction can be done by plunging a piece of sodium into a glass gas filled with chlorine gas. A lot of heat is produced in this reaction.
boring stuff
PbCl2 --> Pb2+ + Cl-
It is not a chemical reaction, it is only a dissociation reaction:NaCl-------------------------Na+ + Cl-
