Q2.
The diagram shows a cell from the lining of the lung. This cell is specialised to allow gases
to pass through quickly.
(a). Use words from the box to label structures A, B and C.
cell
membrane
chloroplast
cytoplasm
mitochondria
nucleus

the answer is a. co2, this would be colder than the : )

explanation:

i believe it is c.) 1575 j.

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 :
