The warmer road surface at the end of a sunny day is the black road because during the day it absorbed more radiation (sunlight) than the withe one
The properties of the atomic orbital are actually
dependent on the quantum numbers.
size of atomic orbital: governed by the principal quantum
number (n)
shape of atomic orbital: governed by the angular momentum
quantum number (l)
orientation in space: governed by the magnetic quantum
number (ml)
Since we are asked about the shape, hence the correct answer
is:
angular momentum quantum number (l)
Answer:
Potential Energy:
- Hot water
- Ball at the top of a hill
- Battery
- Food
Kinetic Energy:
- Wave in the ocean
- Ball rolling down a hill
- Spinning motor
- Person running
Explanation:
Potential energy is the energy that is capable of generating work as a consequence of the position of a body.
The kinetic energy of a body is that energy that it possesses due to its movement.
Answer:p-hydroxybenzaldehyde is stronger acid to phenol
para-cyanophenol is stronger acid to meta-cyanophenol
o-fluorophenol is stronger acid to p-fluorophenol.
Explanation:
The PKa tool relative to Ph are used to contrast the pairs.
The pKa of phenol is 10. The pKa of p-hydroxybenzaldehyde is 9.24
The pKa for meta-cyanophenol is 8.61 and the pKa for para-cyanophenol is 7.95.
The pKa value of o-fluorophenol is 8.7, while that of the p-fluorophenol is 9.9. It's obvious that the inductive effect is more dominant at ortho-position, which results in a more acidic nature
The pKa is the pH value at which a chemical species will accept or donate a proton. The lower the pKa, the stronger the acid and the greater the ability to donate a proton in aqueous solution.
Answer : The molarity of the chloride ion in the water is, 5.75 M
Explanation :
As we are given that 16.6 % chloride ion that means 16.6 grams of chloride ion present 100 grams of solution.
First we have to calculate the volume of solution.
Now we have to calculate the molarity of chloride ion.
Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.
Formula used :
Now put all the given values in this formula, we get:
Thus, the molarity of the chloride ion in the water is, 5.75 M
