Answer:
it's A
Explanation:
The given element is, fluorine is a non-metal with symbol (F). It is a gas and belongs to the group 17 and period 2.
The atomic number of fluorine = 9
The number of electrons = 9
Answer:
[Ar]4s²
Explanation:
The electronic configuration of calcium is given as follows;
1s²2s²2p⁶3s²3p⁶4s²
The electronic configuration of argon, Ar is 1s²2s²2p⁶3s²3p⁶
Given, that there is a similarity be tween the electronic configuration of all the shells of the an atoms of argon and an atom calcium, except for the added valence shell electrons in calcium, the electronic configuration of calcium can be represented by the symbol of an atom of argon, followed by the electonic configuration of the valence shell as follows
The electronic configuration of calcium with argon as base = [Ar]4s².
Answer:
Two advantages are: Its cheap and it is a renewable energy source. Two disadvantages are it's not windy everyday and it will take up a lot of space for windmills.
Explanation:
Given two electrons with charge of 1.5x10^-10 m
The electostatic force between them is determined by this formula:
F = kq1q2/r^2
where
k = 9x10^9
q1 = q2 = 1.5x10^-10
r = 2.82x10^-15
F = 9x10^9 * (1.5x10^-10)^2 / 2.82x10^-15
= 71808.51
So if you’re looking at a graph, the favored rxn is forward if product amount is higher at equilibrium, or the reverse rxn is favored if the reactant amount is higher at equilibrium.
You can tell through looking at the K value by seeing if it’s a large number, product is favored which means the forward rxn is favored, but if it’s smaller that means he reactant is favored, meaning the reverse rxn is favored.
