People who can’t do the homework read this comment:
Zn+HCl -> ZnCl2+H2
Zn=1, H=1, Cl=1
Zn=1, Cl=2, H=2
Answer:-
Zn+2HCl=ZnCl2+H2
Zn=1, H=2, Cl=2
Zn=1, Cl=2, H=2
I’m very sure this answer is correct
I have understood by the video maam.

Zn+2HCL=ZnCl2+H2
Do you teach online? grade 7 science
No online teaching.Only videos are available.
3:52 Mistake molecules exist independently and elements does not exist independently 😅😅

After balancing the equation
Maam how elements are stable
Elements are stable when the shell or outermost shell is completed.
