Answer:
3.974 x 10¹³ mg
Explanation:
To find the amount in milligrams (mg), you need to multiply the given number by the conversion, 1,000 mg/g. This conversions exists as a ratio which compares the amount of mg per every 1 g. It is important to arrange the ratio in a way that allows for the cancellation of units (grams should be in the denominator).
1,000 mg = 1 g
3.974 x 10¹⁰ g 1,000 mg
----------------------- x ------------------- = 3.974 x 10¹³ mg
1 g
Answer:
I am guessing it is B. Non-metal, metals, metalloids
Answer:
A) Dilute the unknown so that it will have an absorbance within the standard curve. Once the diluted unknown concentration is determined, the full strength concentration can be calculated if the dilution process is recorded. Beer's law only applies to dilute solutions, so diluting the unknown is better than making new standards.
Explanation:
Beer's law states that <em>absorbance is proportional to the concentrations of the absorbing species</em>. This is verified in the case of diluted solutions (0≤0.01 M) of most substances. <u>As a solution gets more concentrated, solute molecules interact between themselves because of their proximity. </u>When a molecule interacts with another, the change in their electric properties (including absorbance) is probable. That's why <u>the plot of absorbance versus concentration stops being a straight line</u>, and <u>Beer's law is no longer valid.</u>
Therefore, if the absorbance value is higher than the highest standard, dilutions should be made. Once this concentration is determined, the full strength concentration can be calculated with the inverse of the dilution.
Lipids are made up of long hydrocarbon chains and is not soluble in water.
Hence, Option C is correct answer.
<h3>What is Carbohydrates ? </h3>
Carbohydrate is water soluble macromolecule because they are small polar molecules contains many -OH functional groups that makes it hydrophilic.
<h3>What is Nucleic acid ?</h3>
Nucleic acids are long polymeric chain. They are hydrophilic in nature. Nucleic acid are soluble in water because of their polar nature.
<h3>What is Lipids ? </h3>
Lipids are hydrophobic and they are generally water insoluble because lipids are non polar molecules. Lipids are oily or greasy molecules. Lipids are made up of glycerol molecule. It includes fatty acids.
Thus from the above conclusion we can say that Lipids are made up of long hydrocarbon chains and is not soluble in water.
Hence, Option C is correct answer.

<span> It is due to strong ionic bonding between the anion and cation
HCl, HF have low boiling point due to covalent bond between the elements if that answers the question if you were asking why.</span>
