Good quiz (although I did poorly). Horsepower is a unit of power not energy right? Maybe change to Kilowatt hour.

Thank's for this slightly tougher science quiz! Just two nitpicks:

- In question 4 there's a typo, the correct spelling is seismograph.

- In question 14, cellulose is actually a carbohydrate, making both answers technically correct, and if someone wanted to be *really* nitpicky, cotton contains a tiny amount of pectin, which is another carbohydrate, so that anser would be even more correct - maybe change it, e.g. to hydrocarbon? That's definitely a wrong answer then.

Also, while I am not a chemist, I am not sure if a reaction of dilute nitric acid and calcium would not also release hydrogen gas. Calcium and Magnesium are chemically so similar that I'd be surprised if there was such a black-and-white difference between the two reactions. But I am not sure about that one.
