Note: Above question is incomplete. Complete question is <span>What type of chemical reaction is so3(g) + h2o(l) → h2so4(aq) a) Neutralization b) Decomposition c) Combination d) Single displacement reaction ............................................................................................................... Solution: In current context, following things may be noted 1) Neutralization reactions: In neutralization reactions, acid and base combine to form salt and water. b) Decomposition reaction: R</span><span>eaction in which a single substance broken down two or more smaller substances is refereed as decomposition reaction. Decomposition reactions are characterized be present of single molecule on reactant side. c) Combination reaction: In a recombination reaction</span><span> two or more molecules combine to form a single product. d) Single displacement reaction: R</span><span>eaction in which an element within a compound is displaced by a another element is referred as single displacement reaction.
Above reaction satisfies the criteria of combination reaction, hence correct answer is option C, combination. </span>
By going from the top to the bottom of a group, the atomic number increases. That would mean that:
The number of orbitals increases, as there are more electrons.
A higher atomic number implies an increasing number of neutrons.
As there are more electrons, they get farther from the nucleus. The farther an electron is from the nucleus, the easier it is for the electron to be removed from the atom.
