Lithium has one available electron in the outer (valence) shell (2s¹).
1s² 2s¹
Maybe it's [Acid] and [H+ ions]
Answer: 
Explanation:
To calculate the moles, we use the equation:

Given mass of theobromine
= 0.064 g
Molar mass of theobromine 

Answer:
resistance = 4 Ω
Explanation:
Data Given:
voltage = 12 volt
current = 3 amps
Resistance of the circuit = to be calculated
Solution:
The resistance of the circuit can be calculated by Ohm's law formula.
Resistance have a unit that is ohm (Ω)
Ohm's formula
R = V/I
Where
R = resistance
V = voltage
I = current
Put value in the above formula
R = 12 volt / 3 amps
R = 4 (volt/amps)
R = 4 Ω
Unit of Resistance
R = volt / amps = Ω
So, resistance = 4 Ω
