Answer:
Option (D) freezing point depression
Explanation:
Calcium chloride is added to the roadways after a snowstorm because it reduces the freezing point of the ice. Further more, it has been observed that the calcium chloride also produces enough heat which enhances the melting of the ice as it produces an exothermic reaction.
I believe the answer is D.
Scientists are biased, and want to prove their specific hypothesis is right.

Explanation:
half if diameter is radius or 1.55 and double the radius is 3.10 or the length of the diameter. you have a height given, so use the radius and heaight to plug it in the circular cylinder calculator and you get 56.98496
When the electricity flows into a tube, gas atoms crash inside producing invisible ultraviolet rays. There is a white phosphor coating that turns the invisible rays into visible light. In a plasma tv the cells are like tiny cfls only coated in phonsophers that are rgb
Answer : The ions present in the solution of 
are 
and 
in aqueous state.
Explanation :
When is in aqueous solution then they dissociates into their ions.
The reaction in aqueous medium is,
The charge on potassium ion is +1 and on carbonate ion is -2. To neutralize the charge on carbonate ion, two potassium ion must be used.
Therefore, the ions present in solution of are and [tex]CO^{2-}_3[tex] in aqueous state.
