So here is my first question In the combustion of a certain hydrocarbon, 16.0 grams of CO2 is produced. This represents a 75% yield. What is the theoretical yield? A) 12g B)21.3g C)32.0g D)44.0g I know the answer but i don't know how to get it. Thanks in advance. My second is this Barbecues...

First of all I hope this is the right section of the forums My other was deleted because i posted at the wrong forum.

Thanks

I also have another problem in regards to finding the maximum lift to drag ratio I have been given a graph of airspeed over drag graph where airspeed is x-axis and drag is y axis I have to find out maximum lift to drag ratio at what airspeed and when it occurs Please help ASAP

How does the air going downwards make air go upwards i don't understand Im sorry

I need help with understanding bernoulli's principle, how an aerofoil develops lift i have horrible knowledge and understanding on how it works And how the aerofoil produces lift in regards to bernoulli's principle. Diagrams would help a lot Thanks
