CHEMISTRY!!! PLEASE HELP, i need someone to check my answers?

Question

can you please check if these are right?

Magnesium + hydrochloric acid -> magnesium chloride + hydrogen

zinc + hydrochloric acid -> zinc chloride + hydrogen

Iron + hydrochloric acid -> Iron chloride + hydrogen

Copper + hydrochloric acid -> Iron chloride + hydrogen

Lead + hydrochloric acid -> lead chlorich + hydrogen

Aluminium + hydrochloric acid -> Aluminium + Hydrogen


I just started chemistry so i'm still unsure about everything...

How do i turn them all into symbol equations ?

Answer 1

magnesium- Mg

hydrochloric acid HCl hydrogen and chlorine

magnesium chloride Mg Cl

hydrogen H

zinc Zn

zinc oxide ZnO

iron- Fe

iron chloride- FeCl

NUMBER 4 IS WRONG copper + hydrochloric acid = copper+ hydrochloric acid

NUMBER 6 IS WRONG aluminium + HCl = aluminium + HCl



P.S caps is not me yelling its Just to grab your attention

Answer 2

number 4 and 6 are wrong.



copper + hydrochloric acid --> copper chloride + hydrogen



Aluminum + hydrochloric acid --> Aluminum chloride + hydrogen



remember nothing can just disappear, the law of conservation of matter. Copper doesn't become iron they are 2 different elements! nothing is added its just a reaction between what you had initially. if you start with chloride you end with chloride, etc.





Hope that helped. Good luck with chemistry. I really enjoyed it!





Mg + HCI --> MgCl + H



Zn + HCI --> ZnCl + H



Fe + HCl --> FeCl + H



Cu + HCl --> CuCl + H



Pb + HCI --> PbCl + H



Al + HCI --> AlCl + H



Remeber you must balance these equations to make sure you have the same number of each on each side.



also HOCL BRIF (hydrogen, oxygen, chloride, bromide, iodide, and flouride) all exist in pairs!

Answer 3

#4...Copper + HCl does not give Iron chloride.

#5..Lead chlorich ?

#6...Aluminium chloride + hydrogen.



1...Mg + 2HCl = MgCl2 + H2.

2...Zn + 2HCl = ZnCl2 + H2.

3...Fe + 2HCl = FeCl2 + H2.

4...Cu + 2HCl = CuCl2 + H2.

5...Pb + 2HCl = PbCl2 + H2.

6...2Al + 6HCl = 2AlCl3 + 3H2.
