The best way to solve this is to list all the elements out and count them.
Count subscripts first (if there is no subscript then there is 1 atom)
Then multiply by the coefficients
To balance write a coefficient and multiply
<span>3H2+N2--> NH3
H 2 x 3 = 6 H 3 (x2) = 6
N 2 N 1 (x2) = 2
Your answer is 2 . . . to balance this equation you will need a coefficient of 2</span>
I'm certain that the answer is Sr
Radon is produced by uranium rocks underneath a house.
They're not important when solving math problems in class because you need to get the correct and accurate answers hence don't need to change them into significant figures
<span>The correct answer among the choices given is option D. Copper does not form a diatomic molecule. A diatomic molecule has only two atoms.
Diatomic molecules are molecule that are composed of two same atoms which are
bonded covalently. An example are oxygen, it exist as O2 and chlorine, it
exist as Cl2.</span>
