Answer:- 47.62 mL
Solution:- It is a dilution problem where we are asked to calculate the volume of 15.75 M perchloric acid solution required to make 500.0 mL of 1.500 M solution.
For solving this type of problems we use the dilution equation:
Where, 
is the concentration of the concentrated solution and 
is it's volume.
is the concentration of the diluted solution and 
is it's volume. Let's plug in the values in the equation and solve it for .
On rearranging this for :
So, 47.62 mL of 15.75 M perchloric acid are required to make 500.0mL of 1.500 M solution.
Answer:
- 0.36 m/s.
Explanation:
- For the reaction: <em>a + 2b → c,</em>
<em>∵ The initial rate of the reaction = - δ[a]/δt = - 1/2 δ[b]/dt = 0.180 m/s.</em>
∴ The initial rate of the reaction = - 1/2 δ[b]/dt = 0.180 m/s.
∴ - 1/2 δ[b]/dt = 0.180 m/s.
<em>∴ δ[b]/dt </em>= (- 2)(0.180 m/s) =<em> - 0.36 m/s.</em>
Idk cuz that's really complicated
I believe it is A accumulation of lactic acid in the muscles of her limbs.
Explanation:
well when you heat ice the individual molecules gain kinetic energy. but until the temperature reaches it's melting point they don't have the energy to break bonds and hold their crystal structure. So, the temperature remains constant until the ice has melted. Hope this helped. Good luck on your project!
