Answer:
K = [H₂]² [ O₂] / [H₂O]²
Explanation:
The equilibrium constant of any reaction can be written as,
K = [product]/ [reactant]
For given reaction:
Chemical equation:
2H₂O → 2H₂ + O₂
equilibrium constant:
K = [H₂] [ O₂] / [H₂O]
In stoichiometric calculations, we will put the coefficient of balanced equation in given equilibrium constant equation.
K = [H₂]² [ O₂] / [H₂O]²
Answer:
1.09 mL
Explanation:
Density is a measure of a substance's mass over its volume.
d = m/v
We can rearrange the equation to solve for volume, using algebra.
v = d/m
Therefore v = 6.35/5.80 = 1.09 mL
Answer:
5.6
Explanation:
since HCl is a strong acid we know that it completely dissasociates into H+ and Cl-
We can just treat the HCl as the H+ concentration and take the -log
-log(2.5E-6) = 5.6
Answer:
Explanation:
A solid, at a given temperature, has a definite volume
and shape which may be affected by changes in
temperature. Solids usually increase slightly in size
when heated (expansion) and usually
decrease in size if cooled (contraction).A liquid, at a given temperature, has a
fixed volume and will take up the shape of any
container into which it is poured. Like a solid, a
liquid’s volume is slightly affected by changes in
temperature.
A gas, at a given temperature, has neither a definite
shape nor a definite volume. It will take up the shape
of any container into which it is placed and will
spread out evenly within it. Unlike those of solids
and liquids, the volumes of gases are affected quite
markedly by changes in temperature.
