Answer:
D. So electrons can flow from one electrode to another
Explanation:
An electrochemical cell is any cell in which electricity is produced by reason of a chemical change.
An electrochemical cell consists of two electrodes, these two electrodes are connected using a wire.
Usually, electrons flow from one electrode to another via this wire thereby enabling the electrochemical processes of oxidation and reduction in the cell to proceed effectively.
The Lewis structure of P₄ is shown in 3-D form. The two bottom corner P atoms are facing right in front of us, one P atom behind the two, and one P above it. Each line represents 2 electrons. When you add the lone electrons, you get a total of 20 valence electrons.
Formal charge of each P: 5 - (2 +1/2*6) = 0
Answer:
C. 3
Explanation:
volume = length×width×height
3×3×3=27
Explanation:
The given compound is:
AlCl₃
- ionic formula - it is a combination between a metal and non - metal with an electronegativity difference greater than 0.7
- 3 chlorine atoms - from the compound, we see that the compound is made up of 1 aluminum atom and 3 chlorine atoms.
- Aluminum is the cation
- Chlorine is the anion
A cation is the positively charge specie and the anion is the negatively charged one.
Al³⁺ + 3Cl⁻ → AlCl₃
