There is no reaction because of the common ion effect(which in this case is K)if there were a reaction the products would be the same as the reactants so no reaction happens
Answer: Option (D) 30N
Detailed Solution:
According to Newton's second law:
F = ma --- (A)
Given:
mass = 5kg
acceleration = 6 m/s^2
F = ?
Plug all the value in equation (A)
F = (5)(6)
Ans: F = 30N
The answers
A) a
B) a
C) an
D) the

Bohr's model was unable to calculate or it required precise information about position of an electron and its velocity. It is very difficult to calculate velocity and position of an electron at the same time because electron i too small to see and may only be observed if peturbed, for example we could hit the electron with another particle such as photon or an electron, or we could apply electric or magnetic field to the electron. This will inevitably change the position of the elctron or its velocity and direction. Heisenberg aid that more precisely we can define the position of an electron, the less certainity we are able to define its velocity and vice versa.
In short, first option is correct one
Answer:
The mass density will be doubled
Explanation:
- Density is given by dividing the mass of a substance by its volume.
- An increase in mass causes an increase in density and vice versa, while a decrease in volume causes an increase in density and volume.
- Therefore, when the volume is halved, then the density will be doubled if the mass is kept constant.
- This has no effect on the number of moles as the mass is constant.
