Answer:
KNO₃(s) + 35,1 kJ → K⁺(aq) + NO₃⁻(aq)
Explanation:
In the reaction:
KNO₃(s) → K⁺(aq) + NO₃⁻(aq)
The <em><u>heat absorbed</u></em> for the reaction (Because the temperature decreases) is:
Q = C×m×ΔT
Where C is specific heat (4,18J/g°C); m is mass (100g); ΔT is (30,0°C-21,6°C = 8,4°C)
Replacing:
Q = 4,18J/g°C×100g×8,4°C
<em><u>Q = 3511 J</u></em>
Now, moles of KNO₃ are:
10,1g×(1mol / 101g) = <em><u>0,1 moles.</u></em>
Heat of solution in kJ/mol is:
3,511 J / 0,1 mol = <em><u>35,1 kJ</u></em>
As the heat was absorbed for the reaction, right answer is:
<em>KNO₃(s) + 35,1 kJ → K⁺(aq) + NO₃⁻(aq)</em>
That means the reaction needs the heat to occurs.
I hope it helps!
Answer:
Oxidized and reducing agent: manganese.
Reduced and oxidizing agent: mercury.
Explanation:
Hello!
In this case, for the reaction:
We keep in mind that the species that increase the oxidation state is the oxidized one whereas the one that decrease the oxidation state is the reduced one; therefore manganese is the oxidized one as well as the reducing agent because it goes from 0 to +2 and mercury the reduced one as well as the oxidizing agent because it goes from 2+ to 0.

Calculate the energy of quantum of radiant energy with a
frequency of 5.00 x 10^11/s. this can be solved using Planck-Einstein Equation
E = hf
Also known as Planck's Relation, the energy of a photon is
given by:
, where:
E = Energy (J)
h = Planck's Constant (J*s) = 6.626070040×10−34 Js
f = Frequency (Hz) = 5.00 x 10^11/s
E= 3.31x10^-22 j
