1) If I have 4 moles of C2H4, how many moles of CO2 will be produced based on the balanced equation? 2) If I have 50g of C2H4, how many grams of CO2 will be produced?

3) If 24 grams of C2H4 is ignited to a temperature of 450 degrees celsius, then cooled to 200 degrees celsius, how much heat energy will be released if the specific heat of C2H4 is 2.063 J/g C?

I don't know but I can help you figure it out..

1) Calculate the number of moles of CO2 by the formula n=PV/RT, where P is the pressure from Step 3, V is the volume from Step 2, T is the temperature from Step 1 and R is a proportionality constant equal to 0.0821 L atm / K mol.

2) Approx.  1.7  ⋅  g  of ethylene are required

3) 32.53 L of  C O 2

Hopefully this helps at all :)

that tool would be a compass

the ratio of the conjugate base to the acid required to attain the desired ph.
