Answer:

e) P + O2 → P2O5

balanced equation

4P + 5O2 → 2P2O5

f) NaCl + F2 → NaF + Cl2

balanced equation

2NaCl + F2 → 2NaF + Cl2

g) K + MgBr2 → KBr + Mg

balanced equation

2K +MgBr2 → 2KBr +Mg

h) Mg + O2 → MgO

balanced equation

2Mg + O2 → 2MgO

i) Al + O2 → Al2O3

balanced equation

4Al + 3O2 → 2Al2O3

hope this helps you!

2p is the correct representation for the sub-shell with n = 2 and l = 1.
boyakko [2]

Explanation:

Principle Quantum Numbers : It describes the size of the orbital and the energy level. It is represented by n. Where, n = 1,2,3,4....

Azimuthal Quantum Number : It describes the shape of the orbital. It is represented as 'l'. The value of l ranges from 0 to (n-1). For l = 0,1,2,3... the orbitals are s, p, d, f...

s = 1 orbital

p = 3 orbitals

d = 5 orbitals

f = 7 orbitals

For n = 4

l = 0 to (n-1) = 0 to 3 = (4s , 4p , 4d , 4f)

Number of subshells = 4

Number of orbitals =         1 + 3 + 5 + 7  = 16

The maximum number of electrons the n = 4 shell can contain:

Each orbital can holds upto two electrons, then 16 orbitals will have :

16\times 2=32

32 is the maximum number of electrons the n = 4 shell can contain

Lucia is playing with magnetic toy vehicles. She has two identical toy vehicles (purple and pink) that start on opposite sides o
pentagon [3]

Answer:

The potential energy of both toy vehicles (purple and pink) decreased. Since the pink toy was moved closer to the magnet, it will have less potential energy because of the short distance it will take to travel to the magnet. Although the purple toy is now closer to the magnet, it is still pretty far and will have a somewhat big potential energy when traveling to the magnet.

Explanation:

Hey, I'm in middle school and I had the same question for a science test, I'm not sure if I am correct but this is what I have.
