Answer: The primary consumers are zooplankton, corals, sponges, Atlantic blue tang, and queen conch.
Explanation:
Answer:
Volume of water
Initial temperature of the solution
Final temperature of the solution
Mass of NH₄Cl
Explanation:
There are two heat transfers involved in this experiment.
Heat of solution of NH₄Cl + heat lost by water = 0
q₁ + q₂ = 0
nΔH + mCΔT = 0
nΔH = -mCΔT
ΔH = -mCΔT/n
So, you must measure
- the volume of water (you will probably use its density to calculate its mass)
- the initial and final temperatures of the solution (to calculate ΔT)
- the mass of NH₄Cl (to calculate the number of moles)
You will probably assume that the specific heat capacity of the solution is the same as that of water, so you won't be measuring it.
The two different mineral elements that a fertilizer can contain are:
- Phosphorus - build up of nucleic acid and ATP
- Nitrogen- synthesis of proteins
<h3>What are fertilizers?</h3>
Fertilizers are chemical substances added to the soil in order to improve crop growth and development.
Fertilizers are artificially made to contain mineral elements that are needed by the plants. Some of the mineral elements are as follows:
- Phosphorus
- Nitrogen
- Pottasium
- Phosphorus helps in the build up of nucleic acids and ATP for energy.
- Nitrogen is useful in the synthesis of proteins.

Answer:
Vapor pressure of the solution is 22.9 torr at 25°C
Explanation:
When a non volatile solute is added to a pure solvent, the vapour pressure of the mixture decrease regard to the pure solvent following the equation (Raoult's law):
Where vapour pressure of the pure solvent (Water) is 23.8torr at 25°C.
Mole fraction of water is the ratio between moles of water and total moles in solution. The solution has a mole fraction of water of:
Replacing in Raoult's law:
<h3>Vapor pressure of the solution is 22.9 torr at 25°C</h3>
