1. Define the two parts of the word polymer, and give a literal definition of polymer. 2. Describe two properties of polymers that depend on their long-chain structure.
3. Name three items that consist of or contain polymers.

poly = many

mer = molecule

polymer = many molecules

I dont know about question 2 sorry lad

glass

ceramics

conposites

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
