The redox reaction given is,
Cu₍s₎ + 2Ag⁺₍aq₎ ---------> Cu²⁺₍aq₎ + 2Ag₍s₎
The equilibrium constant for this reaction is as follow,
Kc = [Cu²⁺][Ag]² / [Cu][Ag⁺]²
Kc = [Cu²⁺] / [Ag⁺]² ∴ {[Cu₍s₎] = 1 & [Ag₍s₎] = 1
So, Above bolded is <span>the concentration equilibrium constant expression for the given reaction.</span>
Answer: Evaporation
Explanation:
When the heat of the sun touches the water, the water molecules heat up and move gradually faster. Over time molecules start to pop out the surface of the water individually.
And then eventually all the water is evaporated into water vapor.
Energy were released from the walnut, q = 1,673.6 J
<h3>Equation :</h3>
To find the energy using formula,
q = mcΔt
where,
q is charge
m is mass
c is specific heat of water
Δt is change in temperature
So, given
t₁ = 50°C
t₂ = 60°C
m = 40g
c = 4.184 J/g
Now putting the values known,
We get,
q = mc(t₂ - t₁)
q = 40g x 4.184 J/g x (60 - 50)
q = 167.36 J x 10
q = 1,673.6 J
<h3>What is heat energy?</h3>
Heat is the thermal energy that is transferred when two systems with different surface temperatures come into contact. Heat is denoted by the letters q or Q and is measured in Joules.
