Answer: PCl₃O
Explanation:
1) The chemical formula tells the composition of a compound in terms of the ratio of number of atoms of each element that consitutes such compound.
2) You use the chemical symbol for each kind of atom (element) and subscripts to the right of each symbol to tell the number of atoms of each element.
3) For example, O₂ means two atoms of oxygen. Al₂O₃ means two atoms of aluminum and 3 atoms of oxygen.
4) Therefore, PCl₃O means a ratio 1 : 3 : 1 for phosphorus, chlorine, and oxygen.
Hence, PCl₃O is the chemical formula of your compound.
Answer:
The aquarium is covered and not in sunlight
Diminishing
Explanation:
The sun is the ultimate source of energy for all life and activities on earth. The aquarium is no exception.
Green plants manufactures food in the process of photosynthesis by combining carbon dioxide and water in the presence of sunlight.
- This food provides all other lives with energy through the break down of energy held in carbon chains.
Is the aquarium now in sunlight or is it covered?
Here is a feeding relationship between plants and fish in a pond. The producer here is the plants. The consumer is the fish.
Using carbon dioxide and water, plants manufactures food. When the amount of carbon starts decreasing it shows that the aquarium is covered.
The source of dissolved carbon dioxide in water is the fish which gives off this gas as it respires. When the fish ceases to respire, it does not have enough food and might have died thereby decreasing carbon dioxide levels.
What is happening to the number of energy storage molecules in the plants and fish as a result?
The energy levels in both plant and fish will begin to reduce because the plant is unable to produce food which the fish depends on.
This will furnish a rapid decline in the energy available in these living organisms since the plants are not able to produce.
Physical properties are those which can be observed without any change in composition of the substance. Hence, a is the answer.
Plate tectonics are the broken plates of earth that move around and form the different plate boundaries
