Molar Mass of Calcium carbonate:-








Now



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.
Answer: 1.
moles
2. 90 mg
Explanation:

According to stoichiometry:
1 mole of ozone is removed by 2 moles of sodium iodide.
Thus
moles of ozone is removed by =
moles of sodium iodide.
Thus
moles of sodium iodide are needed to remove
moles of 
2. 
According to stoichiometry:
1 mole of ozone is removed by 2 moles of sodium iodide.
Thus 0.0003 moles of ozone is removed by =
moles of sodium iodide.
Mass of sodium iodide=
(1g=1000mg)
Thus 90 mg of sodium iodide are needed to remove 13.31 mg of
.
The most reactive metal on the periodic table is Francium, However, Francium is an artificial element and only minimal quantities have been produced, so for all practical purposes, the most reactive metal available is Cesium, in the alkali metal family.
ANSWER In theory, Francium, in practice the Cesium
