The atomic and mass numbers of the daughter isotope, which emits a beta particle 91, 232
Isotopes belong to the same elemental family but have different ratios of neutrons to protons, making them different substances. On the Periodic Table, each element's atomic number is based on how many protons are in its nucleus.
Isotopes are two or more different atom types that share the same atomic number and place in the periodic table but have different quantities of neutrons in their nuclei, resulting in various nucleon numbers. Despite having various atomic weights and physical characteristics, they exhibit roughly the same chemical activity. Isotopes are variations in the mass number, "A," of an element's atoms that share the same number of protons (atomic number, "Z") but a different number of neutrons.

Answer
Omega-3 fatty acid
Explanation:
The monomers are small units or molecules which join with each other end in a huge to end and give rise to the polymers.
DNA and albumin:
If we talk about albumin it is a protein which is present in eggs. All proteins are made up of monomers of amino acids. Similarly, DNA is also a polymer because it is made up hundreds and thousands of small monomeric units called nucleotides.
glycogen:
It is also a biological polymer where several monomer units of glucose are joined together through alpha acetal linkages.
Omega-3 fatty acid:
It is not a polymer. Its a group of fatty acids that contain a double bond at carbon of 3rd position from one end of the carbon chain that was initiated from methyl group and contains one carboxyl group located at the other molecular end. For example: Alpha-Linelenic acid.
Therefore, Omega-3 fatty acid is the right option.
Hope it helps!
Answer:
The balanced equation is given below:
SiO2 + 4HF —> SiF4 + 2H2O
The coefficients are 1, 4, 1, 2
Explanation:
The equation for the reaction is given below:
SiO2 + HF —> SiF4 + H2O
The above equation can be balance by as follow:
There are 4 atoms of F on the right side and 1 atom on the left side. It can be balance by putting 4 in front of HF as shown below:
SiO2 + 4HF —> SiF4 + H2O
Therefore are 4 atoms of H on the left side and 2 atoms on the right side. It can be balance by putting 2 in front of H2O as shown below:
SiO2 + 4HF —> SiF4 + 2H2O
Now the equation is balanced.
The correct option is D.
The solubility of silver chloride in water is higher than that of silver bromide and the solubility of silver bromide in water is higher than that of silver iodide. This illustrates the differences in the reactivites of elements in the same group.
