How many atoms are in 9.8 moles of NaCl?

a lot but im pretty sure if u just take avogadros number and multiply it by 9.8 u get the answer

Explanation:

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

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 :
