The mass isnt relevant
520 - 120 = 400
400 / 8 = 50

Answer : The formal charge on central Cl atom is -1.
Explanation :
The given molecule is,
First we have to determine the total number of valence electrons in,
As we know, chlorine has 7 valence electrons.
Total number of valence electrons in = 3(7) + 1 = 22 electrons
Electrons used in bonding pair = 4
Electrons used as lone pair = 22 - 4 = 18
Now we have to calculate the formal charge on central Cl atom.
- Formal charge = Number of valence electrons of a central atom - (2 × Number of lone pairs) - Number of bond pairs
Formal charge on central Cl atom = 7 - (2 × 3) -2 = -1
Therefore, the formal charge on central Cl atom is -1.
The lewis-dot structure of is shown below.
Answer: They all transmit energy
Explanation: Because they can all transfer energy, they can transmit it as well. Waves form because particles are disturbed by this transfer of energy.
Answer: Option (d) is the correct answer.
Explanation:
An oxidizing agent is a specie which accepts electrons and gets reduced in a chemical reaction.
In the given reaction,
Oxidation state of Al changes from 0 to +3, therefore, it is reducing agent. Whereas oxidation state of Br is changing from -2 to -3 this means Br is gaining electrons, therefore, it is an oxidizing agent.
Thus, we can conclude that the statement is the oxidizing agent because its oxidation number decreases.
Answer:
12 g of 12C to three significant figures maybe?
Explanation:
tell if correct or not im sorry fi it isnt :c
