1. 200/2=100. 100/2=50. 50/2=25. So that's 3 to get to 25.
2. 11.46/3=3.82
The answer is (2).
Arsenic's atomic number is 33.
Hence his electronic configuration is

hence his valence electrons are

.
5 valence electrons
Answer:
Melting
Explanation:
Once heat is added it will turn to a liquid
Answer:
subtract
Explanation:
To find the net force of two bodies going in opposite directions, we must subtract the forces this is because they are not additive forces.
- The net force is the resultant force acting on a body.
- This resultant force is the single force that will produce the same effects as all given forces.
- When forces are directed oppositely on a body, they are subtracted from each other to find the net force.
1. Equal
2. Properties
3. Heat
4. Reverse
