If you star out using 10.0 grams of NaHCO3 and excess of acetic acid, how many moles of CO2 can form? How many grams of CO2 can form? (Show all your work) 4. How many moles of CO2 are contained in a balloon that has a volume of 28.3 cm3 at 25.0°C and 1.001 atm?

Answer 1

Following is the - complete Answer -&- Explanation - for the first question ( i.e. Question - 1 ) - of the given: Question Set...in.....Typed format...

$\Rightarrow$Answer:

IDEAL GAS: ( definition ) An Ideal gas - is a Hypothetical Gas, the molecules of which don't occupy any space, and the molecules don't interact with each other, and the gases which obey the Ideal Gas Laws...completely, are called as Ideal Gas...

$\Rightarrow$Explanation:

An Ideal Gas is one which exists only theoretically , and have the following properties. They are supposed to occupy negligible space ( such that its volume becomes absolute - and the volumes of the molecules can be neglected ), of the environment. The molecules of the Ideal Gas, are not expected to react with each other, or have any other interactions, except for having - perfectly elastic collisions - with each other. The IDEAL GASES - are expected to obey IDEAL GAS LAWS - completely.

Therefore, we get the above Definition - for Ideal Gases...
