Answer: Braces are used by the people to correct the alignment and position of tooth or teeth in the jaw.

Explanation:

The teeth braces must have strong tensile strength and must create a constant pressure on the teeth so as to allow the straightening of the teeth.

The strong force of attraction between the molecules of the braces material that can be steel, nickel, molybdenum, copper, titanium. This makes the bracing material rigid on the teeth.

An ionic compound has the general form, xcly. which option for x and y correctly completes the formula?
igor_vitrenko [27]
Answer:
Case 1:
            X  =  Any element from Group I
            
                       i)    H
                       ii)   Li
                       iii)  Na
                       iv)  K
                       v)   Rb
                       vi)  Cs

            Y  =  1

Case 2:
            X  =  Any element from Group II
            
                       i)    Be
                       ii)   Mg
                       iii)  Ca
                       iv)  Sr
                       v)   Ba
                       vi)  Ra

            Y  =  2

Case 3:
            X  =  Any element from Group III
            
                       i)    B
                       ii)   Al
                       iii)  Ga
                       iv)  In
                       v)   Ti

            Y  =  3

Explanation:
                   The general formula given is as follow,

                                                    XCly

So, if X has +1 oxidation state, then it will require only one Cl atom with oxidation number -1 to form a neutral compound, therefore, y = 1.

If X has +2 oxidation state, then it will require two Cl atoms with oxidation number -1 to form a neutral compound, therefore, y = 2.

If X has +3 oxidation state, then it will require three Cl atoms with oxidation number -1 to form a neutral compound, therefore, y = 3.
