Answer:
Your question is incomplete.
But what I can help you with is once a redox reaction occurs, one element oxidizes and another is reduced, generating the equilibrium of the reaction.
On the other hand, it is important to clarify all the redox reactions, reactions of reducing factors (positive protons) and oxygen that oxidize.
Explanation:
example:
Reduction half-reaction: {2 e ^ - + Cu ^ 2 + -> Cu} {2 e ^ - + Cu ^ 2 + -> Cu}
Half oxidation reaction: {Fe -> Fe ^ 2 + + 2 e ^ -} {Fe -> Fe ^ 2 + + 2 e ^ -}
or more frequently, also called general equation:
{Fe + Cu ^ 2 + -> Fe ^ 2 + + Cu} {Fe + Cu ^ 2 + -> Fe ^ 2 + + Cu}
Answer:
mass of calcium chloride = 290.49g
mass of water = 494.61 g
Explanation:
The percentage of calcium chloride in the mixture is 37.0%
It means in each 100g of mixture the mass of calcium chloride = 37.0 g
if the total mass of the mixture = 785.1 g
the mass of calcium chloride =
=
The mass of water = 785.1-290.49 = 494.61 grams
So much heat is released like atleast OVER 9000
I believe the answer would be through the movement of the molecules, the higher the temperature the more the molecules move around and vibrate.
the complete question in attached figure
Let
x------------------- > actual yield
y------------------- > theoretical yield
z------------------- > percent yield
we have that
z=x/y
we know
x=47 g
y=56 g
therefore
z=47/56=0.839 ---------------- > 83.9%
the answer is the option C 83.9%
