Area = L • W
Area = Length (multiplied) by the width
So if you had a rectangle that had a length of 4 and a width of 7 you would do 4 • 7 = 28 so the area of that rectangle would be 28.
Answer: hydrogen has 0.0504% and Fluorine has 0.950%
Explanation: H= 1.00794
F= 18.9984
1 X 1.00794+ 1 X 18.9984= 20.00778g/mol
H= 1.00794/20.00778= 0.0504%
F-18.9984/20.00778= 0.950%
This is the correct equilibrium represented in the question
Blue + 4 Br- (aq) <---> green + 6H2O (l)
Answer:
Addition of NaBr supplied the Br- ions which moved the equilibrium position towards the right hand side. The forward reaction is endothermic hence its rate decreases when the reaction mixture is placed in an ice bath.
Explanation:
Blue + 4 Br- (aq) <---> green + 6H2O (l)
Looking at the equilibrium represented above, addition of Br- moves the equilibrium towards the right hand side, that is, the green colour. Addition of NaBr increases the Br- concentration and drives the forward reaction hence the equilibrium position shifts towards the right hand side. The fact that the solution turns blue when placed in ice bath reveals that the forward reaction is endothermic. Decreasing the temperature shifts the equilibrium position towards the left hence the resurgence of the blue colour.
I think the answer is: D) The reaction could spend more time in the reverse direction than in the forward direction.
It is c. Earth’s oceans
bc water is necessary to sustaining life on Earth, and helps tie together the Earth's ... The ocean plays a key role in this vital cycle of water.
