Answer 1

yes u r ri8...it is very simple dude...
delta ng=no. of moles of gaseous products-no. of moles of gaseous reactants

enjoy ;-)~♥~

Answer 2

To find the value of delta ng in an equation, only the gaseous molecules of products and reactants are considered. Delta ng of an equation is simply the difference between the number of gaseous molecules of products and the number of gaseous molecules of reactants.  

The relationship is as follows:

Delta ng of an equation = number of gaseous molecules of products - number of gaseous molecules of reactants.
