Answer:
Explanation:
Our
sample yielded 1g of
and 16g of
, but our unknown sample yielded 2 times as much
for the same amount of
.
What does this mean? that the H:O proportion for the unknown sample is twice the H:O proportion for the
sample.
What is the H:O proportion for the
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:
and you should recognize that formula, for it is one of the most common compounds on earth, Water.
<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>
<span>Answer:
(16.2 g C2H6O2) / (62.0678 g C2H6O2/mol) / (0.0982 kg) = 3.9704 mol/kg = 3.9704 m
a.)
(3.9704 m) x (1.86 °C/m) = 7.38 °C change
0.00°C - 7.38 °C = - 7.38 °C
b.)
(3.9704 m) x (0.512 °C/m) = 2.03 °C change
100.00°C + 2.03 °C = 102.03 °C</span>
Cells can generate from non living matter is the answer
<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>
