Question

In Figure 9-2, are both kinds of atoms in balance, only nitrogen atoms in balance, only oxygen atoms
in balance, or neither kind of atom in balance?
Figure 9-2

A) The equation is balanced for both kinds of atoms

B) The equation is balanced for oxygen atoms only

C) The equation is balanced for nitrogen atoms only

D) The equation is balanced for either kind of atom

Answer 1

Answer:

C) The equation is balanced for nitrogen atoms only

Explanation:

nitrogen (black one) - 1 before and 1 after reaction

oxygen (white one) - 3 before and 2 after reaction

So,

C) The equation is balanced for nitrogen atoms only
