Among these Options the Option B contains a Balance chemical equation. Equation is as follow,
<span>2Na </span>₍s₎<span> + MgF</span>₂<span> → 2NaF </span>₍s₎ <span> + Mg </span>₍s₎
There are two Na atoms (or moles) at right hand side and two at left hand side.
There are two F atoms (or moles) at right hand side and two at left hand side.
There is one Mg atom (or mole) at right hand side and one at left hand side.
Answer: a) 0.06 M
b) 3.13 grams.
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
Moles of
The balanced reaction for dissociation will be:
Thus for 4 moles of , there is 1 mole of
Thus moles of
Molarity of
Thus the molarity of the solution = 0.06 M
b) Mass of =
Thus mass of Wenzhou use is 3.13 grams.
Answer:
I do not think it will happen
Explanation:
The result is not general and can only occur when there is higher temperatures and pressure. Only when there's high temperature and pressure, will the solution precipitate.
More so; kinematically, the result is limited though it can happen in thermodynamics environment.
Answer:
The answer is n = 4 , l = 1, m= +1 , ms = -1/2
Explanation:
When br atom gains one electron its atomic number becomes
36 br = 35
electronic config. = [ar] 3d 104s 24p5 br- = 36 = [ar] 3d 104s 24p6
so the electron goes into 4p that means
n = 4 , l = 1, m= +1 , ms = -1/2
Answer:
Explanation:
Okay I just took this test and I will just tell you now
D is not the answer.
Sorry I couldn't be more help
