What structural feature must be present in order to form homopolymer polyster

Hi, please help me with this question, especially with parts 1 and 2.

Describe the process of catalytic reforming in the petroleum refining industry

your answer must also include:

1)   A balanced chemical equation, physical states included, and reaction conditions stated.

2)    Examples of a product formed from catalytic reforming (in petroleum refining) and its use.

Catalytic reforming is a chemical process used to convert petroleum refinery naphtha distilled before describing the reaction chemistry of the catalytic reforming process as a petroleum refinery includes many unit operations and unit processes.

a.     Explain the different types of chemical bonds and describe how each bonds are formed .

b.     Using Lewis dot structures, indicate the movement of electrons during the formation of the ionic compound Calcium Oxide (CaO) from Calcium (Ca) and Oxygen (O).

c.      Draw a sketch of the geometry of NF₃ molecule. Indicate in your sketch any lone pairs of electrons on nitrogen.

d.     Give the molecular geometry for the atoms in the following structure at positions 1,2, and 3.

a.     Why a solid has a definite shape but a liquid does not.

b.     Why a liquid has a definite volume but a gas does not.

c.      Why negative ions are larger than their corresponding atoms.

d.     How scandium, a transition metal forms an ion with a noble gas structure.

e.     How the effective nuclear charge changes as you        

      move from left to right across the periodic table and 

      why?

f.       How the effective nuclear charge changes as you        

move from left to right across the periodic table and why.

g.     The information that you can get from a symbol of an element in the periodic table.

State the names of the functional groups present in 3-hyroxypentanoicacid

Explain the following:

a. Why a solid has a definite shape but a liquid does not.

b. Why negative ions are larger than their atoms.

c. How scandium, a transition metal forms an ion with a noble gas structure.

d. How the effective nuclear charge changes as you move from left to right across the periodic table and why?

e. The information that can be obtained from a symbol of an element in the periodic table.

a) Calculate the pressure exerted by 0.0153 moles of CO2 gas in a container of 1.467 L at 20.0C.

b) What is the volume of a 15.0 g sample of propane (C3H8) gas at Standard Temperature Pressure?

c) Assuming that the volume of the container in question part (b) above remains constant, what would be the pressure of the propane at room temperature (25 °C)?

d) A 1.00 g gaseous sample of hydrocarbon occupies a volume of 385 mL at 330 K and 1.00 atm. Find the molar mass of the compound.

e) Calculate the number of atoms of He(g) that are needed to exert a pressure of 4.0 X 10–2 kPa in a 15 mL container at a temperature of –23°C.

Determine the number of atoms of O in 22.3 moles of Al2(CO3)3

The stability of metal carbonyl complexes falls off markedly as we go to the right of group 10 in the periodic table. For example, Cu complexes only bind CO weakly. Why is this? What oxidation state, of the ones commonly available to copper, would you expect to bind CO most strongly?

What is the energy (in J) of a mole of photons that have a wavelength of 701 nm? (h = 6.626 × 10⁻³⁴ J • s and c = 3.00 × 10⁸ m/s)
