Answer:
2K + 2H2O → H2 + 2KOH
Explanation:
Find how many atoms you have on both sides then add 2 to both sides.
Reactant: Products:
K: 1+1=2 K: 1+1=2
H: 2+2=4 H: 3+1=4
O: 1+1=2 O: 1+1=2
Therefore it is balanced. Hope this helps
Answer:
Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles (neutrons or protons).
Answer:
Empirical Formula:
The empirical formula of a compound is the simplest whole-number ratio of the numbers of the different atoms that compose the molecule of the compound. The empirical formula looks like a molecular formula.
C

Explanation:
These are called quantum numbers: there are 4, but the first three are mainly used, only in orbital notation will you use all four.
The first is the electron's energy level or "shell", used as n. (Principle QN)
The second relates to the shape of the orbital and is used as l, when n and l are put together it defines the sublevel or subshell. (Angular Momentum QN)
The third one relates to the orientation of the electrons in that sublevel used as m(sub)l. (Magnetic QN)
The fourth one relates to the spin states of the electron, since they spin opposite directions, used as m(sub)s. (Electron Spin QN)
What you are looking for is something from the left side of the periodic table (the metals), combined with something from the right side of the periodic table.
SiCl4 is something from the middle with something on the right. Not the answer.
HCl is a possible answer, but it is not the best one, because Hydrogen can be on both sides. It is not quite as willing to give up its electrons as the answer.
CCl4 has the same problem as A.
The answer is C
Ca is in column 2 just about as far left as you can get.
Cl is in column 17 which is just about as far right as you can get.
