Explanation:

1. To find the density of a substance, the mass and volume of the compound/substance must must be known.

Density is the mass per unit volume of a substance;

 Density =  

Therefore, we must know the mass and volume of a substance to determine their density

2.

  Using the density equation and knowing the given parameters, it is easy to find their density.

Simply weigh the liquids and find their volume using a volumetric flask.

3.

The liquid with the highest density will sink to the bottom the most.

Because honey has the highest density, it will sink to the bottom of the column.

4. At the very top is corn oil because it is the lightest due to its lowest density value.

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
