What volume of CO2 would be produced at STP if 20.0 g of C6H1206 reacts with O2?

The blackbody curve for a star name zeta is shown below. what is the peak wavelength for this star ?

Define dew point. i am writing this part to be able to ask the question

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
