After a lightning storm, the Rodriguez family notices the TV is no longer working because a power surge burned an electric component of the TV. The correct option is B.
What is lightning?Lightning is a natural phenomenon that occurs when there is a collision of negative and positive charged particles. It appears as light or spark of electricity into the earth. It shines and affects the eyes if directly seen.
Lightning occurs when there is thunder or rain, lightning causes destruction to the earth, the houses, trees, and people are also impacted by this. The TV was not working because there was a short circuit due to lightning.
Thus, the correct option is B. A power surge burned an electric component of the TV during a lightning storm.

How many electrons can be present in an atom having three principal
energy levels? *
Answer:
18 electrons
Explanation:
The third principal energy level has one s orbital, three p orbitals, and five d orbitals, which can each hold up to 10 electrons. This allows for a maximum of 18 electrons. The fourth and higher levels have an f sublevel in addition to the s, p, and d orbitals.
Answer:
18 electrons
Explanation:
The five d orbitals can hold up to 10 electrons. Thus, the third level holds a maximum of 18 electrons: 2 in the s orbital, 6 in the three p orbitals, and 10 in the five d orbitals.

What is the molarity of a sodium carbonate solution containing 32.52 g Na2CO3 dissolved in enough water to make 822 ml of solution?
NEED ASAP PLEASE!!
The molarity of a Sodium carbonate solution : 0.373 M
Further explanationGiven
32.52 g Na₂CO₃
822 ml of solution = 0.822 L
Required
The molarity
Solution
Molarity shows the number of moles of solute in every 1 liter of solution.
[tex]\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}[/tex]
mol of solute = mol of Na₂CO₃ :
= mass : MW Na₂CO₃
= 32.52 g : 106 g/mol
= 0.307
Molarity :
= n : V
= 0.307 mol : 0.822 L
= 0.373 M
How do chemists use systems and order in their work?
Answer:
5 point) Chemists used systems and order because they study the basic unit of all forms of matter, which is the atom . However, there are several different kinds of atoms, called elements . Chemists organize these elements using the periodic table .
