Answer:
D
Explanation:
because in a decay series a daughter nuclei may be stable or decay itself. that starts a decay series

Hydrogen bonds are stronger than the dipole dipole attraction force present in any molecule.
<h3>What is bonding in molecules?</h3>
Bonding is a type of attraction force which is present between the different atoms or elements of any substance.
- Dipole dipole attraction force is a weak force as compared to the hydrogen bonding and present between any two oppositely charged atoms.
- Hydrogen bond is present between the hydrogen atom and more electronegative atoms like O, S, N and F.
Hence main difference is that hydrogen bond is only present between the hydrogen atom and more electronegative.

The correct answer is
Energy of electrons depends on light’s frequency, not intensity.
As per photoelectric effect, if we incident a light on metal surface it will results into emission of electron from it
if we increase the number of photons the number of electrons will increase however if we increase the frequency the number of photons will not increase
While if we increase frequency the energy of electrons will increase as
Energy of photon = Work function of metal + kinetic energy of electrons
The molarity of a solution is the number of moles of a substance divided by the volume in liters prepared.
, where n is number of moles and V is the volume in liters.
In order to calculate the mass of solute we need to convert the volume and molarity to moles
Now that we have moles we use the relative formula mass of NaCO₃, We have 1 Na atom, 1 C atom and 3 O atoms, thus
