Answer:

The correct answer is A.

Explanation:

Ectothermic is the main characteristic of a group of living beings that are not capable of generating, by metabolic or physiological processes, their own internal heat. These organisms must rely on external heat sources to reach certain body temperature. When the environmental temperature is not the appropriate one, they must take care of their activity in order to save energy.

Have a nice day!

How many moles of oxygen are in 25.45 g of caco3?
emmainna [20.7K]
From the periodic table:
mass of oxygen = 16 grams
mass of calcium = 40 grams
mass of carbon = 12 grams
mass of CaCO3 = 40 + 12 + 3(16) = 100 grams
Therefore, each 100 grams of CaCO3 contains 3 moles of oxygen
To know the number of oxygen moles in 25.45 grams, we will simply do cross multiplication as follows:
number of oxygen moles = (25.45 x 3) / 100 = 0.7636
