Answer:
8 electrons
Explanation:
As per the <u>octet rule</u>, the atoms possess a tendency to bond in a manner that every atom must have at least eight(8) electrons in its outermost/valence shell. It can be done either by sharing, gaining, or losing electrons from one atom to another. According to this rule, flourine would have 8 electrons in its outer shell after two shared electrons are given to it.
Answer:
B. 10⁻⁶ m
Explanation:
Frequency is the inverse of period, which is correlated with its wavelength. In other words, the smallest wavelength will give you the highest frequency.
10⁻⁶ m is the smallest value in the answer choice so that's your answer.
To find the molarity of the compound, simply determine the molar mass of MgCl2 and then convert 50 g to moles using the molar mass of the compound. Then convert 150 ml to L = 0.15 L
Then divide the moles amount by the volume in L.
