Question

Question No: 10
The atomic number
of elements A and B
are 14 and 8,
respectively.
If the total number of
atoms of element A
and element B
provided is 50 and
40 respectively for a
chemical reaction,
what is the total
number of molecules
produced if they
react with each
other?​

Answer 1

Answer:

14 silican

8 oxygen

80 molecules

Answer 2

Answer:

the element with atomic number 14 is Silicon

and with atomic number 8 is Oxygen

so the element A is Silicon and element B is oxygen

it is given that,

the total number of atoms of element A is 50 and element B is 40 so

when they undergo chemical reaction the total number of molecules produced will be 90

because it follows the law of conservation of mass which states that mass can neither be created nor be destroyed in a chemical reaction.
