<span>Generally, a hydrogen bond can be characterized as a proton shared by two lone electron pairs. It occurs when a hydrogen (H) atom, covalently bound to a highly electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F), experiences the electrostatic field of another highly electronegative atom nearby.

   Among the choices in the bond (-N...H-O) one side of the Hydrogen is bonded to a highly electronegative atom with a lone pair (-N) and the other side is directly bonded with a highly electronegative atom (O-).

    So -N...H-O- shows a hydrogen bond.</span>

Formula New Combination Predicted Formula
creativ13 [48]
Answer:

<span>Formula      New Combination                     Predicted Formula
</span>

NaCl            potassium + chlorine                KCl


AlCl₃             aluminum + fluorine                AlF₃

CO₂              tin + oxygen                              SnO₂

MgCl₂           calcium + bromine                   CaBr₂

HCl               cesium + iodine                       CsI


<span> CCl₄              silicon + bromine                     SiBr₄</span>

Explanation:

1) The question is incomplete. The first part is missing.

This is the first part of the question.

<span>Applying the principle that the elements of a particular column in the Periodic Table share the same chemical properties, complete the following chart. The first one has been done for you.
</span>

2) This is the given chart:

<span>Formula      New Combination                     Predicted Formula
</span>

Cu₂O           silver + oxygen                          Ag₂O   ← this is the example.

NaCl            potassium + chlorine 

<span> AlCl₃             aluminum + fluorine </span>

CO₂              tin + oxygen 

<span> MgCl₂           calcium + bromine </span>

<span> HCl               cesium + iodine </span>

<span> CCl₄              silicon + bromine </span>


3) This is how you find the new formula to complete the chart.

i) NaCl            potassium + chlorine 

Since potassium is in the same group of sodium, you predict that in the new formula Na is replaced by K giving KCl.

ii) AlCl₃             aluminum + fluorine 

Since fluorine is in the same group that Al, then you predict that in the new formula Cl is replaced by F leading to AlF₃

iii) CO₂              tin + oxygen 

Since tin is in the same group that C, you predict that in the new formula C is replaced by Sn leading to SnO₂

iv) MgCl₂           calcium + bromine 

Since calcium is in the same group that Mg, and bromine is in the same group that Cl, you predict thea in the new formula calcium replaces Mg and bromine replaces Cl, leading to CaBr₂

v) HCl               cesium + iodine 

Since H is in the same column that cesium and Cl is in the same colum that iodine, you predict that in the new formula Cs replaces H and I replaces Cl leading to: CsI


<span> vi) CCl₄              silicon + bromine
</span>

Since silicon is in the same column that C and bromine is in the same column that Cl, you predict that in the new formula Si replaces C and Br replaces Cl, leading to SiBr₄
