In order to balance this equation you need to count each element and how many of the individual elements are in the equation.
_H2+N2=2 NH3
You multiply the 2 (Which is the coefficient) by the 3 (which is the subscript) This would equal 6 which indicated there are 6 hydrogen atoms on the right side so the left side should also have 6 hydrogen atoms
The missing coefficient on the left side must multiple the 2 to become 6 hydrogen
Answer=3

Explanation:
The approximate total size of the human nuclear genome is 3,200,000,000 base pairs. 1 to 1, 4% encode proteins, 24% are non-coding regions and the rest correspond to intergenic regions.
Answer:
See explanation
Explanation:
The postulates of the kinetic theory of matter are;
- Every substance is made up of tiny particles called molecules. Brownian motion and diffusion illustrates this fact.
- The molecules that compose matter are in constant random motion.
- There exists an attractive force between the molecules in matter. The attractive forces between gases are negligible. Solids have a definite shape and volume due to a high magnitude of intermolecular forces. Liquids have a volume but no definite shape due to weaker intermolecular forces. Gases have the weakest intermolecular forces hence the do not have both a shape and volume. They take on the volume of the container into which they are put. This illustrates this fact.
- The actual volume occupied by gas molecules is negligible relative to the volume of the container. The fact that gases are easily compressible illustrates this fact.
- Temperature is a measure of the average kinetic energy of the molecules of a body.
