The resistance of the appliance is 64.1 Ω.
<u>Explanation:</u>
As per the Ohm's law, which states that the electric current is in direct proportion to the voltage and is in inverse proportion to the resistance. It is given by the expression as,
V = IR
Where V is the voltage (V) = 150.0 V
I is the current (amps) = 2.34 amps
R is the resistance (ohm) or Ω = ?
Now we have to rearrange the equation to get the resistance as,
Now we have to plug in the values as,
= 64.1 Ω
So the resistance of the appliance is 64.1 Ω.
Answer:
they have an equal number of positive and negative charges
Answer: 0.156 mol
Explanation:
To find the moles of 17.2 g K₂S, we need to know the molar mass to convert.
The law of cross-cutting relationships states that an igneous intrusion or any other geologic feature of a rock must be younger than any rock it cuts.
Explanation:
Igneous intrusion is formed when the magma intrudes into the cracks of an existing rock.When the melted rocks solidifies and cool down the resulting feature is the Igneous intrusion
The law of cross cutting is basically a principle of geology that states that the geological feature of a rock that cuts the other is always younger.

b)
It has not reached equilibrium because the silver concentration is not yet equal to the value of Ksp.
c)
Yes it will dissolve in order to establish the equilibrium.
