Remember, look at the coefficients in the balanced equation! Here are three mole ratios:
1 mole<span> N2 / </span>3 moles<span> H2.</span>
3 moles<span> H2 / 2 moles NH3.

Because of the crystal structure of the ice, ice has lower density than liquid water. So the volume of the ice of same mass is greater than water. When melting, the volume will decrease.
Metals on the left side, metalloids on the staircase, nonmetals on right side
The nuclear equation that describes the alpha decay of Polonium-210 can be written like this:
