Practice sketching molecules, using the number of bonds an atom can form as a guide. a. SH2
b. Below is one enantiomer of lactic acid. Draw the other enantiomer. (Remember a pair of enantiomers is two molecules that are mirror images of each other.)

How does concentration affect reaction rate

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?
