2 SO₃ --> 2 SO₂ + O₂
I 12 0 0
C -2x +2x +x
---------------------------------------------
E 12-2x 2x x
Since the moles of SO₂ at equilibrium is 3 mol, 2x = 3. Then, x = 1.5 mol. So, the amounts at equilibrium is:
SO₃: 12 - 2(1.5) = 9
SO₂: 2(1.5) = 3
O₂: 1.5
The formula for K basing on the stoichiometric reaction is:
K = [SO₂]²[O₂]/[SO₃]²
where the unit used is conc in mol/L.
K = [3 mol/3 L]²[1.5 mol/3 L]/[9 mol/3 L]²
<em>K = 0.0556</em>
Answer:
<h3>The answer is 200 cm³</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 150 g
density = 0.75 g/cm³
We have
We have the final answer as
<h3>200 cm³</h3>
Hope this helps you
Answer:
The temperature of the system once the equilibrium has been reached = 372.55K
Explanation:
Heat capacity of gold = 129 J/Kg*c.
Heat capacity of water
4,184 J/Kg*c.
Mass of gold = 75g = 0.075Kg
Mass of water = 200g = 0.2Kg
From conservation of energy
m1×C1×(t11 - t2) = m2×C2×(t2- t21)
Substituting we have
0.075 × 129×(1000-t2) = 0.2× 4184×( t2 -300) =solving for t2, we have
933.55×t2 = 347790
or t2 = 372.55K
The temperature of the system once the equilibrium has been reached = 372.55K
The energy conversions in the Rude Goldberg device design is as follows:
- a quartz falls off from the roof: potential to kinetic
- the quartz hits and lift a soda bottle: kinetic to potential
- The soda bottle moves hits a battery: potential to kinetic
- a battery which slides along into a torch that lights up: chemical to light
<h3>What is a Rube Goldberg device?</h3>
A Rube Goldberg device uses a set of reactions that work in succession with one event triggering the next event in the form of a chain reaction until the final event is completed.
The Rude Goldberg device design is as follows:
The design is of a unit that produces light when a quartz falls off from the roof. It then hits a plastic soda bottle and its velocity is converted into potential energy used to lift a soda bottle. The soda bottle then on rising hits a battery which slides along into a torch which then light up.
In conclusion, Rude Goldberg devices shows various forms of energy conversion.
