Answer:
25.0 mol O₂ are required in the second reaction
Explanation:
N₂ (g) + 3H₂ (g) → 2NH₃ (g)
4NH₃ (g) + 5O₂ (g) → 4NO (g) + 6 H₂O(l)
Molar ratio in first reaction is 1:2
For every mol of N₂. I make 2 moles of ammonia. If I have 20 moles of N₂, i'm going to get, 40 moles of ammonia.
In the second reaction, molar ratio between products is 4:5.
If I obtained 40 moles of ammonia in first step, let's prepare the rule of three.
4 moles of ammonia react with 5 moles of O₂
40 moles of ammonia react with ( 40.5) /4 = 25moles
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.

Answer:</h3>
61.3 mL
<h3>
Explanation:</h3>
From the data given;
- Mass of volumetric flask is 109.1 g
- Mass of salt is 5.01 g
- Mass of Volumetric flask and salt is 113.5 g
- Mass of volumetric flask and salt solution is 170.4 g
- Mass of salt solution is 61.3 g
We are required to calculate the volume of salt solution;
We need to know the relationship between density, mass and volume of a solution.
Density = Mass ÷ Volume
Therefore, given mass and density we can find the volume.
Rearranging the formula;
Volume = Mass ÷ density
Assuming the density of salt solution is 1 g/mL
Then;
Volume = Mass of the salt solution ÷ density of the salt solution
= 61.3 g ÷ 1 g/mL
= 61.3 mL
Therefore, the volume of the salt solution is 61.3 mL

im not sure about the amoni acid produced but
AAA produces -> Lys.
ACG produces -> Thr.
and i don't know about the last one
The answer is:
C) Sound is a mechanical wave and needs a medium to travel through while light is an electromagnetic wave.
