Rewrite 0.000000000333 in scientific notation.

Hello!

Order of magnitude of a measure is an estimate of the base power 10 closest to a given measure.

The scientific notation (N) of 0.000000000333 (x), being  (number of decimal places) y, knowing that the scientific notation according to the rule of scientific notation, before the comma can only have the numbers 1 to 9, let's see:

note: Moved 10 decimal places to the right negatively

I Hope this helps, greetings ... DexteR! =)

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 :
