Answer: A volume of 37.5 mL of 0.300 M NaF would be required to make a 0.0450 M solution of NaF when diluted to 250.0 mL with water.
Explanation:
Given: = 0.300 M, = ?
= 0.0450 M, = 250.0 mL
Formula used is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that a volume of 37.5 mL of 0.300 M NaF would be required to make a 0.0450 M solution of NaF when diluted to 250.0 mL with water.
<span>I think that the effective nuclear charge increases as you go up a group and across a period.
so maybe Rh, K, Ti, Mg, P
I hope I helped :)</span>
<span>we know that each
element has an unique spectra and it can be used to identify the
element. it shows that the energy levels of the electrons and different colors are the result of different wavelengths.
hope it helps

2NaCl + Br2
This is because Na (Sodium) still needs to retain the coefficient or amount of two. Since Chlorine already has 2 on the reactants side, having a two in front would make sense so both elements can have a two.
Bromine would have the subscript of two as in the reactants side of the equation, it is also under the coefficient of two. Thus, it would need to carry it to the products side in order to keep the equation balanced.
Hope this helps!
Answer:
Magnetism, and electrical charge, and gravitation are examples of forces that act at a distance. There are other such forces at the atomic level.
