A 17g sample of H2O2 was decomposed to yield 1g of H2 and 16g of O2 An unknown sample containing only H and O was decomposed to
ludmilkaskok [199]

Answer:

Explanation:

Our H_2O_2 sample yielded 1g of H_2 and 16g of O_2, but our unknown sample yielded 2 times as much H_2  for the same amount of O_2.

What does this mean? that the H:O proportion for the unknown sample is twice the H:O proportion for the H_2O_2 sample.

What is the  H:O proportion for the H_2O_2 sample? As we can see from its formula, it's 1:1, therefore the proportion for the unknown formula must be 2:1.

That means, two H atoms for every O atom. We could write that as: H_2O and you should recognize that formula, for it is one of the most common compounds on earth, Water.

How does the size change when an atom forms a cation and when an atom forms an anion?
mario62 [17]
<span>A cation is an atom that loses a valence electron. When a valence electron is released there is one electron less to create a repulsive force. The loss of a repulsive force will allow the atom to pull tighter together. An anion would therefore be larger in size due to increased repulsion of the valence electrons.</span>

viktelen [127]
<span>Dried fruits and raisins get terribly soggy after being drenched in milk for a long period of time. They act like a sponge, absorbing all of the milk up making them wet and "soggy". I prefer them to be like that when I eat my cereal in the morning.</span>
