I believe it’s the Distance Traveled that is the dependent variable, because the smooth wood, rough wood and number of students are all fixed. I’m not sure though! I hope this helps.
You are right sugar is a mixture and salad, water and potassium are all wrong.

In order to find the answer, use an ICE chart:
Ca(IO3)2...Ca2+......IO3-
<span>some.......0..........0 </span>
<span>less.......+x......+2x </span>
<span>less........x.........2x
</span>
<span>Ca(IO₃)₂ ⇄ Ca⁺² + 2 IO⁻³
</span>
K sp = [Ca⁺²][IO₃⁻]²
K sp = (x) (2 x)² = 4 x³
7.1 x 10⁻⁷ = 4 x³
<span>x = molar solubility = 5.6 x 10</span>⁻³ M
The answer is 5.6 x 10 ^ 3 M. (molar solubility)
Explanation:
<u>Periodic table is the tabular display of elements that are arranged by the increasing atomic number.
</u>
Structure of the periodic table shows various periodic trends.
<u>Significance:
</u>
The periodic table is very important because it gives an organized way to provide lots of information about the elements and how they can be related to one another. The table gives a systematic approach to study the elements and their properties. The table can also be used to predict the properties of the elements which have not been discovered yet.
