1. Two hypothetical elements in the periodic table have different characteristics as shown in the following table.

ELEMENT, ELECTRONEGATIVITY, TYPE OF ION, ELECTRICAL CONDUCTIVITY, BRIGHTNESS


X Low Electro cation ion high conduc brightness yes


Y High Electro anion ion none conduc brightness no






According to the data in the table, answer the following questions.




a. If you were to carry out an experiment with these 2 hypothetical elements, write a hypothesis to differentiate them and write another hypothesis about how they would react with oxygen and water.








HYPOTHESIS 1:






HYPOTHESIS 2:






In four steps, design an experiment (write step 1, step 2, step 3 and step 4) to check and verify what types of links would form these elements X and Y if after a series of reactions these elements join in some type chemical bonding.






STEP 1








STEP 2








STEP 3








STEP 4








b. A series of reactions of elements X and Y are given below, complete these reactions bearing in mind that X has an oxidation number +2 and Y has an oxidation number +6.




I. X + O2  XO






II. Y + O2  YO3.






III. XO + H2O  X(OH)2






IV. YO3 + H20  H2YO4.






V. X(OH)2 + H2YO4  A + H2O.






d. Considering the result (A) in reaction number 5, answer:




I. What type of chemical bond do you think A has?




II. What are its physical and chemical properties?




III. Design a four-step experiment so that you can identify the type of chemical bond that substance A obtained in reaction 5 has. The design must contain at least 2 variables to be measured and 2 hypotheses with these variables.
