Increase the coefficient for NH3. Look at the balance labeled "H" (for hydrogen).
Why are there now 3 hydrogen atoms on
the right side of the balance but 0 on the
left side?

When determining the shape of a molecule, it is important to draw a lewis dot structure first in order to see the total number a. electrons within the moleculeb. bonding and unshared pairs around central atomc. unshared pair within the molecule( i really need it )

What is the atomic mass of an atom that has 6 protons, 6 neutrons, and 6 electrons? a) 6 b) 8 c) + 1 d) 12 e) 18

What is another way to determine mass times acceleration?
