Answer 1

Note: The reactions are not balanced

K + Cl → KCl

Al + F → AlF₃

Sn + O → SnO₂

Ca + Br → CaBr₂

Cs + I → CsI

Si + Br → SiBr₄

Explanation :

New combination and predicted formula of given compounds are shown below in image.

Ionic compounds are the ones which are formed when metal and non-metal combines in their ionic form.

For the formation of compound, all charges on the metal and non-metal should be balanced.

Like, we take an example of compound $CaBr_{2}$, in this the +2 charge of Ca is balanced by the 2$Br^{-}$ ions.
