Any given ammeter will have a range selector; therefore, the least count cannot be generalised. Suppose the range of a given microammeter is... View Article
The rate of reaction, or the speed at which the reaction occurs, is written as the change in concentration of a reactant or product per change in... View Article
Activation energy is the amount of energy to be supplied in order for a chemical reaction to proceed. We can find the activation energy by... View Article
From Newton’s law of gravitation, we know that any two objects in the universe exert a force of attraction on each other. This force is directly... View Article
As one gets closer to the black hole, the flow of time slows down as compared to the flow of time at the surface, far from the centre of the... View Article
“Centre of the mass of a body or system of a particle is defined as, a point at which whole of the mass of the body or all the masses of a system... View Article
The kinetic theory of gas considers the size of the gas particles to be zero. The theory states that the gas particles have no mutual attraction... View Article
An electric field can never be negative. An electric field is a force experienced by the charge divided by the magnitude of the charge. The... View Article
What happens to the intensity of the unpolarized light when it is passed through a polarizer? There is no effect on the unpolarized light.... View Article
The ground state of Helium encapsulates two identical 1s electrons. Removing an electron, we get the He+ ion. The He+ ion is similar to the... View Article
The ionization energy decreases as you move down the group in the periodic table due to the increase in the shielding effect and due to the... View Article
Tollens' test is a qualitative test that is used to distinguish an aldehyde and a ketone. It is based on the principle that aldehydes are readily... View Article
Potassium chromate is a strong electrolyte. Potassium chromate is an inorganic compound with the formula K2CrO4. It is used as a fungicide in... View Article
The following factors govern if a collision between reacting particles will be effective or not: Molecules must collide with sufficient... View Article
The property of being able to cut an object into two significant parts is known as cleavage. In simple words, it is the property of solids to be... View Article
Bond order in a molecule or an ion determines its stability. The higher the bond order, the stronger is the bond, and therefore higher the bond... View Article
Lewis bases are ligands with lesser electronegativity; hence will they will be stronger. Therefore, oxygen or halogen donors are weak field... View Article
