Hey there!
Na + H₂O → NaOH + H₂
First, balance O.
One on the left, one on the right. Already balanced.
Next, balance H.
Two on the left, three on the right. Let's add a coefficient of 2 in front of NaOH and a coefficient of 2 in front of H₂O, so we have 4 on each side.
Na + 2H₂O → 2NaOH + H₂
Lastly, balance Na.
One on the left, two on the right. Add a coefficient of 2 in front of Na.
2Na + 2H₂O → 2NaOH + H₂
This is our final balanced equation.
Hope this helps!
Answer:
Electrons are in "orbitals", regions of space where there is high probability of being found.
Explanation:
The Wave mechanical model of the atom does not restrict the electrons to certain energy levels only as in the Bohr's model, instead it describes a region around the nucleus called an orbital, where there is a high probability of finding an electron with a certain amount of energy.
Each energy level is composed of one or more orbitals and the distribution of electrons around the nucleus is determined by the number and kind of energy levels that are occupied.
Answer:
Explanation:
If it is at a higher energy level, it is said to be excited, or any electrons that have higher energy than the ground state are excited. They are then called degenerate energy levels.
Idk sorry I just have to answer something or brainily won’t let me ask my question
