The nearest star to the earth is Proxima Centuri. It is 4x1016 meters from New York City. The distance to Perth on the exact
other side of the globe is about 11,000 miles. Given that 1 mi = 1609 m, how many orders of magnitude
further from New York is Proxima Centuri compared to Perth?
Note: An order of magnitude is an estimate of size based on how many multiples of ten something is bigger or smaller compared
to something else. If I have $1 and you have $200 we can say you have 2 orders of magnitude more money than me because it is
two factors of 10 larger. If you had $1,000,000 it would be 6 orders of magnitude more. For this question we don't want you to say
exactly how much farther this star is, but approximate in terms of orders of magnitude.

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?
