I think it is done to prevent extremes in experiments. Also to have a low standard error of measurement. In other words it is done for accuracy.

In much of the world SI units are used in everyday life and not just in science. Why would it make sense for people in the Unite
KiRa [710]

Answer:

Find the explanation below.

Explanation:

It would make sense for the United States to use SI units in everyday life because most calculations they do, in daily activities such as business and science, affect people in other parts of the world. For example, a United States writer who writes about weight in pounds(lb) and ounce(oz) might not be easily understood by a reader in many other countries of the world. This is because the reader might not be able to convert the measurement using the standards of the SI units where weight is measured in kilograms(kg).

The international system of units is the upgraded system of measurement from the metric system and it is used by almost all the countries of the world except three countries of which the United States is included.

Why is ethanol added to the reaction mixture of fat and base in soap making?
sveta [45]
<span>Since the oil and water do not mix, some solvent (the ethanol) that is able to dissolve partially in both the oil and the water helps to facilitate the reaction of sodium hydroxide with the fatty acid (to produce the fatty acid salt - soap, and water).</span><span>

According to the Arrhenius theory a substance that yields hydrogen ions as the only ion in an aqueous solution is
Nuetrik [128]
According to Arrhenius theory of acid and bases, an acid is a proton donor, while base donates hydroxyl ions. Further, acid and base reacts to form salt and water.
Consider following example.
HCl   +     H2O        →      Cl-         +      H3O+
here, HCl has donated a proton, hence it is an acid.
Now consider following reactionHCl     +      NaOH           ↔     NaCl      +        H2O
in this reaction, HCl donates proton, hence it is acid. On other hand, NaOH donates hydroxyl ion (i.e. OH-), hence it is a base.

How many carbon dioxide molecules must be added to rubp to make a single molecule of glucose?
Pani-rosa [81]

Answer:

6 carbon dioxide molecules

Explanation:

The Calvin cycle generates the necessary reactions for the fixation of carbon in a solid structure for the formation of glucose and, in turn, regenerates the molecules for the continuation of the cycle.

The Calvin cycle is also known as the dark phase of photosynthesis or also called the carbon fixation phase. It is known as the dark phase because it is not light dependent as is the first phase or light phase .

This second stage of photosynthesis fixes the carbon of the absorbed carbon dioxide and generates the precise number of biochemical elements and processes necessary to produce sugar and recycle the remaining material for continuous production.

The Calvin cycle uses the energy produced in the light phase of photosynthesis to fix the carbon dioxide (CO2) carbon in a solid structure such as glucose, in order to generate energy.

The glucose molecule composed of a six-carbon main structure will be further processed in glycolysis for the preparatory phase of the Krebs cycle, both part of the cellular respiration.

The Calvin cycle produces in six turns a six-carbon glucose molecule and regenerates three RuBP that will be catalyzed again by the RuBisCo enzyme with CO2 molecules for the restart of the Calvin cycle.

The Calvin cycle requires six molecules of CO2, 18 ATP and 12 NADPH produced in the light phase of photosynthesis to produce a glucose molecule and regenerate three RuBP molecules.
