I need help on this bcuz i certainly didnt understand back on the lessons 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

Y High anion none 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,

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.
