Answer: Magnesium
Explanation:
Sodium, number of electrons= 11
Aluminum, number of electrons= 13
Magnesium, number of electrons= 12. which is greater than sodium but less than aluminum.
Potential energy is energy that isn’t moving but has potential and staying still
Kinetic energy is energy that is moving
like if your at the top of a slide you have potential energy, when you go down the slide thats kinetic energy
Answer:
If the material is opaque, light is reflected or absorbed. If the material is transparent, all light is transmitted. If the material is translucent, the light is scattered. The higher the frequency, the more energy the light waves have. The lower the frequency, the less energy the light waves have.
Explanation:
I'm literally learning about it right now and I got it right.
Molecular formula: C8H6N2
Empirical formula: C4H3N
Answer:
Al4C3 + 12H2O = 3CH4 + 4Al(OH)3
Explanation:
Not sure if any explanation is needed but always start with the most complex compound. In this case it is Al(OH)3. You can see that there is 4 Aluminiums on the other side so I would start by putting a 4 next to the Al(OH)3. This now gives me 12 Hydrogens and 12 Oxygens on the right side. I put a 3 next to the CH4 to balance the Carbons on the left side. This leaves me with 12 Oxygens and 24 Hydrogens on the right side. This ends up being perfect because I can put a 12 next to the H2O.
