Answer:
Beta emission
Explanation:
In beta emission, a neutron is converted into a proton thereby emitting an electron and a neutrino. A neutrino is a particle that serves to balance the spins.
When a nucleus undergoes beta emission, the mass number of the parent and daughter nuclei remain the same while the atomic number of the daughter nucleus is greater than that of its parent by one unit.
Hence, in beta emission, the daughter nucleus is found one pace to the right of the parent in the periodic table.
Answer : The net ionic equation will be:
Explanation :
Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.
Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
The balanced molecular equation will be,
The complete ionic equation in separated aqueous solution will be,
In this equation the species, 
are the spectator ions.
By removing the spectator ions , we get the net ionic equation.
The net ionic equation will be:
Answer:
The answer to your question is KNO₃ is soluble and Fe(OH)₃ is insoluble.
Explanation:
Data
Potassium hydroxide (KOH)
Iron nitrate Fe(NO₃)₃
Double displacement reaction
3KOH + Fe(NO₃)₃ ⇒ 3KNO₃ + Fe(OH)₃
Conclusion
KNO₃ is soluble because compounds containing alkali metals ions are
soluble and also compounds containing nitrate ion are soluble.
Fe(OH)₃ is insoluble because compounds containing OH are insoluble
except Ba(OH)₂
B ⇒ bromine decolourises, cause its unsaturated hydrocarbon
C ⇒ no change, cause its saturated hydrocarbon
