Answer:
POSITIVE DESCRIBES AN INCREASE IN SPEED AND NEGATIVE DESCRIBES A DECREASE IN SPEED.
Explanation:
Huh I don’t get it what is this
The question is incomplete, the complete question is;
Arrange the isotopes of chlorine and sulfur in order of decreasing number of neutrons. Rank the isotopes from most to fewest neutrons. To rank items as equivalent S-33,S-36,S-34,Cl-35,S-32,Cl-37
The isotopes of sulphur arranged in order of decreasing number of neutrons is; S-36, S-34, S-33, S-32. The isotopes of chlorine arranged in order of decreasing number of neutrons is; Cl-37, Cl-35.
Isotopes are atoms of the same element having different mass numbers but the same atomic number.
Isotopes differ in their number of neutrons. The number of neutrons is obtained by subtracting the atomic number of an isotope from its mass number.
The number of neutrons in the isotopes of sulphur are;
S-36 (20 neutrons)
S-34 (18 neutrons)
S-33 (17 neutrons)
S-32 (16 neutrons)
The number of neutrons in the isotopes of chlorine are;
Cl-37 (20 neutrons)
Cl-35 (18 neutrons)

This problem is asking for the dissolution reaction of barium fluoride, both the equilibrium and Ksp expressions in terms of concentrations and x and its molar solubility in water. Thus, answers shown below:
<h3>Solubility product</h3>
In chemistry, when a solid is dissolved in water, one must take into account the fact that not necessarily its 100 % will be able to break into ions and thus undergo dissolution.
In such a way, and specially for sparingly soluble solids, one ought to write the dissolution reaction at equilibrium as shown below for the given barium fluoride:
Next, we can write its equilibrium expression according to the law of mass action, which also demands us to omit any solid and refer it to the solubility product constant (Ksp):
![Ksp=[Ba^{2+}][F^-]^2](https://tex.z-dn.net/?f=Ksp%3D%5BBa%5E%7B2%2B%7D%5D%5BF%5E-%5D%5E2)
Afterwards, one can insert the reaction extent, x, as it stands for the molar solubility of this solid in water, taking into account the coefficients balancing the reaction:
Finally, we solve for the x as the molar solubility of barium fluoride as shown below:
![2.5x10^{-5}=(x)(2x)^2\\\\2.5x10^{-5}=4x^3\\\\x=\sqrt[3]{\frac{2.5x10^{-5}}{4} } \\\\x=0.0184M](https://tex.z-dn.net/?f=2.5x10%5E%7B-5%7D%3D%28x%29%282x%29%5E2%5C%5C%5C%5C2.5x10%5E%7B-5%7D%3D4x%5E3%5C%5C%5C%5Cx%3D%5Csqrt%5B3%5D%7B%5Cfrac%7B2.5x10%5E%7B-5%7D%7D%7B4%7D%20%7D%20%5C%5C%5C%5Cx%3D0.0184M)
