The correct answer is BI₃
Lewis acid refers to a compound that could accept a pair of electrons, while Lewis base refers to a compound that could donate a pair of electrons.
In the mentioned reaction,
In NH₃, nitrogen exhibits a lone pair of electrons and is functioning as a Lewis base. In BI₃, the boron is deficient for an electron pair, thus in order to complete its octet it functions as a Lewis acid.
Hurricanes, Tornadoes, and Thunderstorms all have low-pressure air.
Density = Mass / Volume
Input the values in their respective places and then use algebra to solve for volume.
Hope that helps.
Solvent is used to dissolve the solute in the solution
Alpha decay lowers the atomic number of an element. The correct option is B. Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, which is an helium particle. During this process, the atomic number of the nucleus is reduced by two and the mass number is reduced by 4.
