The carboxylic acid has the molecular formula C4h8O2.Analysis of the alcohol shows it has the following percentage composition by mass: 52.2% carbon; 13.0% hydrogen; 34.8% oxygen. Calculate the empirical formula for the alcohol​

What natural processes produce large quantities of co2

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?

How many grams of phosphorus are contained in 5.09 moles of phosphorus?
