The given question is incomplete. The complete question is:
An acidic solution at 25°C will have a hydronium ion concentration ________ and a pH value ________.
![[H_3O^+]](https://tex.z-dn.net/?f=%5BH_3O%5E%2B%5D)
> 
M, pH < 7.00
< , pH < 7.00
< ,, pH > 7.00
> ,, pH > 7.00
Answer: > M, pH < 7.00
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7.
![pH=-\log [H_3O^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH_3O%5E%2B%5D)
![7=-log[H_3O^+]](https://tex.z-dn.net/?f=7%3D-log%5BH_3O%5E%2B%5D)
![[H_3O^+]=10^{-7}](https://tex.z-dn.net/?f=%5BH_3O%5E%2B%5D%3D10%5E%7B-7%7D)
As pH of acids is less than 7, the hydronium ion concentration is greater than
Thus the correct option is > M, pH < 7.00
It should be 24 electrons
Kinetic energy of an object can be expressed in terms of its mass m and velocity v as:
KE = 1/2 * m* v²
Thus higher the velocity, greater will be the Kinetic energy. Now, as the box moves along a ramp from top to bottom, its velocity increases and so does the KE. Hence, kinetic energy is maximum at the bottom
Ans B) at the bottom
The answer is 155 pm, hope this helps!
It says you can pick any organ system. Organ systems are Respiratory system, Muscular, Nervous that looks like a brain, and skeleton. Just pick one of these. Say what it does and why its needed for the human?
