Pls solve my problem quickly as i am junior, i am not expert in solving these:
SiO2 + Na2CO3=Na2SiO3 +CO2
So how do CO2 get separated from products,and where did the 1 oxygen atom go, Is this equation needed to be balanced.
Why is helium placed in the group of noble gases? Do it reacts?
Why is hydrogen a non metal, if it is placed in 1a group?
Do displacement reactions only take place between a metal and a non metal and do it only displaces non metal?
How could be argon a non metal if it is a noble gas?
