The idea that the universe began from a single point and
expanded to its current size explains a large number of
observations, including those in the table below.

observations explained:
the universe consists mostly of low-mass elements.
cosmic microwave background is nearly the same in all directions.
light from other galaxies shows that these galaxies are moving away
from earth

in addition, many predictions based on the idea have led
to additional observations that support it. this idea of the
origin of the universe is best classified as a

hi,

the capital city of australia is canberra.

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 :
