Answer:
Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division.
Explanation:
The colour of a substance determines the way it reacts when light rays are incident on it. When light rays strike a dark object, the dark object will absorb all the wavelengths of the light and convert them to heat energy, thereby increasing its temperature. Lighter colors do not absorb all the wavelengths of light, they reflected some depending on the type of color.
Answer:
Yes a soap is a salt
Explanation:
The process of soap production is called saponification. Saponification is the hydrolysis of fats and oils with a caustic alkali such as NaOH or KOH to yield the corresponding sodium or potassium salt of the fatty acid and propane 1,2,3-triol.
Recall that organic salts are compounds of the sort RCOO^-M^+ (such as RCOO^-Na^+). A soap is of the same RCOO^-Na^+ (or K^+) structure indicating that it is a salt where R is the alkyl chain of the fatty acid.
<span>First you will need to know the conversion between atm and mm Hg. It is 1 atm = 760 mm Hg
Then you need to solve for the mm Hg
(0.550 atm) * (760 mm Hg/1 atm) = x mm Hg
x = 418 mm Hg</span>
