How do we know what occurs when dihydrogen reacts with dioxygen?

Answer 1

Well, you do the experiment; at least, you look up the experiment in a text.

This particular chemical reaction is an example of a real chemical reaction, which is the burning of hydrogen gas with oxygen to produce water.

#H_2(g) + 1/2O_2(g) rarr H_2O(g) + "energy"#

There will undoubtedly be a brief mention of this reaction and its potential for the so-called hydrogen economy in your chemistry textbook.

From chemical equations and experimental observations, we know what happens when dihydrogen and dioxygen react: 2H2 + O2 -> 2H2O is the balanced chemical equation for this reaction.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
