Answer:
B. The amount of lee that melted.
Explanation:
The dependent variable is more of what results from an action during an experiment. It is actually what is being tested for. In the experiment, the scientist seeks to understand the effect of salts on melting point of ice. He selects the different salts which can cause a ice to melt (independent variables) then he sets up to find out the effect of the salt on the ice.
He cannot control how much ice will melt. The properties of the salts would determine the extent and rate of the dissolution of the ice pack. This is the dependent variable which relies on the nature of the salt.
Answer:
1.2 mL
Explanation:
<em>This is a problem of simple dilution. The dilution principle simply agrees that the number of moles before dilution must be equal to the number of moles after dilution.</em>
Recall that: number of moles = mass/molar mass or molarity x volume.
Hence, for the dilution principle:
initial molarity x initial volume = final molarity x final volume.
In this case, initial molarity of NaOH = 1 M, initial volume = ?, final molarity = 0.1 M, final volume = 12.0 mL.
Initial volume = final molarity x final volume/initial molarity
= 0.1 x 12/1 = 1.2 mL
It thus means that 1.2 mL of 1 M NaOH would be taken and then diluted up to 12.0 mL mark by the addition of distilled water in order to produce 12.0 mL, 0.10 M NaOH solution.
Answer:
c. red, green and blue.
Explanation:
The three main colors, also known as the primary colors are Red, Green and Blue. The trichromatic theory believes that the human eye and receive light of three different wavelengths (which are red, green and blue) and is able to combine these three different wavelengths in order to see the entire visible spectrum that make up millions of different colors. As can be visualized by the attached picture below.
