Question

firstly see this example:
zn+hcl---->zncl+h2
question: why on earth the atom of hydrogen on right side is 2???
plese help asap and explain :)

Answer 1

Explanation:

first of all, its Zn + 2HCl --> ZnCl2 +H2

to form a ZnCl2 molecule, you need 1 Zinc (Zn) atom and 2 Chlorine atoms. the zinc is given in its pure form, meanwhile the chlorine atoms come from the substance, HCl. now you need 2 chlorine atoms to form ZnCl2, so therefore you need 2 molecules of HCl. so now you have created ZnCl2. there is 2 Hydrogen Radicals that bond with each other and form H2

Answer 2

Answer:

this is because firstly, Valencies of:--

Zn=1

Cl=1

H=1

as well as to stay stable Hydrogen attach one more atom of Hydrogen as a gas

also hydrogen stability is in the form of two hydrogen that's why hydrogen have two atoms on right side

Hopes it help u mark it as a brainlist answer .
