Answer: The thermocline begins at 100 meters of depth.
Step-to-step explanation:-
Thermocline is a transition oceanic water layer between deep and surface water in which water temperature decreases rapidly with increasing depth.
From the given graph it cam be seen that at 100 meters the thermoline begins such that the temperature drops from to
.
Hence, the thermocline begins at 100 meters of depth.
<u>Answer:</u> The mass of water that must be reacted is 56.28 grams.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
....(1)
Given mass of oxygen = 50 g
Molar mass of oxygen = 32.00 g/mol
Putting values in equation 1, we get:
For the given chemical equation:
By Stoichiometry of the reaction:
1 mole of oxygen is produced when 2 moles of water is reacted.
So, 1.5625 moles of oxygen is produced when = of water is reacted.
To calculate the mass of water, we use equation 1:
Moles of water = 3.125 moles
Molar mass of water = 18.01 g/mol
Putting values in equation 1, we get:
Hence, the mass of water that must be reacted is 56.28 grams.
