The correct answer - Dalton
4 NH₃ + 3O₂ --> 2N₂ + 6H₂O
First, make sure that this is a balanced equation.
There are 4 moles of nitrogen on the left side, and 4 moles of nitrogen on the right side.
There are 12 moles of hydrogen on the left side, and 12 moles of hydrogen on the right side.
There are 6 moles of oxygen on the left side, and 6 moles of oxygen on the right side.
The equation is therefore balanced, and we may proceed.
a) the mole ratio for NH₃ to N₂ is 4 to 2, which can be simplified to 2:1 or 2/1.
b) the mole ratio for H₂O to O₂ is 6 to 3, which can be simplified to 2:1 or 2/1.
<span>London forces also known as "induced-dipole-induced-dipole interactions" and are in principle found in every molecule. The interaction occurs from the transient dipoles all molecules have as a result of fluctuations in the instantaneous positions of electrons.
</span><span>Dipole-dipole arises when we are able to set up a polarity in the molecule. So for an example if a highly electro-negative atom is bond to a less electro-negative atom then there will be a polarity in the molecule and we therefore have the dipole-dipole interaction.

Answer:
One way to measure the volume of any irregular object (in your case, a stone) is to submerge it completely under water and measure the change in the height of the water level. This change in the water level (let's say it goes from 50 mL to 65 mL) indicates that the stone has a volume of 15 mL.
