Acertain chemistry class is 1.00 microcentury (μcen) long. what is its length in minutes?

There are several scale to determine the time, weight, distance. The scale of each is large from the micro level to macro. In case of time the standard used lower value is second or micro second and larger value is hour. There are also some units which are easily expressed but contains a large number. Like in case of weight 1 tom is equivalent to 100 Kg or 100000 gm to make the data hand-able the ton unit is used. Similarly the micro-century is often used to express the length of a class in term of time. 1 micro-century is equivalent to 52 minutes. Thus the length of the chemistry class in terms of minutes will be 52.

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.

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 :
