hope it is right..
please mark as brainlist
4. An element A forms an oxide A2O3 the valency of A
The oxide A2O3 is formed by combining two atoms of A with 3 atoms of O. ... As the charge is the combining capacity of the element, the valency is 3 for A.Jan 16, 2014
5. No. of moles of methane = 4/16
no of moles of carbon dioxide = 11/44 = 0.25
as both have same no of moles so they both have same no of molecules.
both have equal number of molecules.
