Chemical property is when something is flammable. That means creating a new substance always. Colorless, odorless, and tasteless are physical properties! I taught that for 31 years.

If you are going to write a quiz about chemistry, it would be good to know chemistry.

Re: Question 3 - hydrogen may be odorless but it is also HIGHLY flammable.

Try applying a lit splint to a 2 litre bottle of hydrogen and see what happens! It explodes! So did the Hindenburg airship. Hydrogen may be odourless but your underwear won’t be if you get too close with a naked flame!💥

The answer to number 3 is wrong. Flammable is a chemical property while odorless is a physical property. Chemical properties are how the substance behaves in certain chemical reactions. Physical properties are determined by your physical senses.

10/10 The last time I took this quiz, I failed miserably. I guess I've learned a lot since then.

If you hold a flame in a stream of hydrogen is will catch fire, it makes a high squeaky sound and the result is water. It doesn't burn for a long time but it does burn when it combines with oxygen. Specifically, hydrogen has a wide range of flammable concentrations in air and lower ignition energy than gasoline or natural gas, which means it can ignite more easily. Because hydrogen burns with a nearly invisible flame, special flame detectors are required.
