Answer:
See below :)
Explanation:
There is an evident reason why some of the solutions Carson's has listed and observed, does conduct electricity and some that do.
A flow of electrical charge is called an electric current. Ions are atoms, or sets of atoms, that contain an electrical charge. There are two types of ions, cation or a positively charged ion containing a deficiency of electrons, and anion or a negatively charged ion which contains a surplus of electrons. When a solution conducts electricity the charge is carried within by ions that move through the solution. The larger the number of ions in the solution, the better the conductivity of the solution is. Pure water does not conduct very well because it contains very few ions, but when table salt (NaCl) is dissolved in the water, this solution does conduct well because the solution contains a more abundance of ions. The majority of the ions come from the table salt, chemically names sodium chloride. Because Sodium contains its sodium ions, and these are positive charge and chloride ions which is a negative charge, it is called an ionic substance. Not every substance is made up of ions, one such example is sugar (C12H22O11). Sugar is made up of uncharged particles also called molecules. Although sugar is a substance its molecules do not hold a charge, thus when sugar is dissolved in water, the solution does not conduct electricity, due to the lack of ions in the solution.
Therefore, depending on the ions that make up the compound, the substance would or would not conduct electricity.
If two particles have the same charge they will repel each other when brought close together.
Answer:
The oxidation state of the carbon is +4.
Explanation:
Calcium is in group 2 of the periodic table, therefore, its oxidation state is +2.
The oxidation state of the oxygen is -2.
As the compound is neutral, the sum of the oxidation states of all atoms must be 0.
Oxidation State Ca + Oxidation State C + (Oxidation State O)×3 = 0
+2 + x + (-2)×3 = 0
2 + x - 6 = 0
x = 6 -2
x = 4
Hence, the oxidation state of the carbon is +4.
Answer: It takes 5.89 s for the concentration of 
to decrease by 88.0%.
Explanation:
As the units of rate constant is 
, the kinetics must be second order.
Integrated rate law for second order kinetics is given by:
= initiaal concentration = 0.590 M
a= concentration left after time t = 
Thus it takes 5.89 seconds for the concentration of to decrease by 88.0%.
Answer:
Organism best adapted to the environment are able to survive in nature!
Explanation:
Suppose there was a green forest but after a volcano eruption all the green colored vegetation is lost and the area turns black . Now some organisms did survive...you have a black rat, and a white rat. You also have vultures flying in sky looking for prey. Overtime, the organism best adapted to environment can reproduce more and survive in nature. In our example, the black rats are the best adapted because their color matches with the environment so the eagles or vultures would have a hard time spotting them, whereas, a white rat in a black environment can be easily spotted so it has less adaptation to the nature.
