Answer:
We have to consume starch and cellulose in large amount in order to increase the consumption of polysaccharides which make our body healthier.
Explanation:
Starch is polysaccharide which is made up of many glucose molecules. it is mostly made in the body of plants and when we eat that plant this starch is transferred to our body and our body use it when it is needed while cellulose also made of hundred of glucose molecules but our body is unable to digest it because our body is unable to break the bonds between the monosaccharide of cellulose. It is good for humans due to the presence of high amount of fibers.
Answer:
- <u><em>The bag with no sunscreen held the most vibrant beads.</em></u>
Explanation:
<em>SPF</em> is the Sun Protection Factor. It indicates how long a person can stay out in the sun before his skin start burning. It is a factor that is multiplied by 15 minutes. SPF 30 means 30 times 15 = 450 minutes. SPF 70 means 70 times 15 = 1,050 minutes.
Thus, the bag covered in <em>SPF 30</em> <em>sunscreen</em> will raise its temperature faster than the bag covered in <em>SPF 70 </em>sunscreen. And the bag with <em>no sunscreen </em>will raise its temperature faster than the other two.
The higher the temperature the more vibrant the particles that consititute the substances, thus, you conclude that the bag that held the most vibrant beads is the bag with no sunscreen.
Remember that the temperature is a measure of the kinetic energy:. The relation is: the higher the temperature the higher the kinetic energy.
Therefore, the more the particles vibrate, the higher the kinetic energy and the higher the temperature.
Democritus, a Greek philosopher, first developed the idea of atoms (around 460 B.C., I believe).
Hope this helps!
A base generally releases a hydroxide ion (OH-) when dissolved in water.
There are exceptions, such as ammonia NH3, which acts as a base but does not produce OH- ions. There are three definitions of acids and bases (Arrhenius, Bronsted-Lowry, and Lewis) and each one looks at acid/base characteristics differently. OH- donation is the Arrhenius definition.
Answer:
Helium and Neon have similar chemical properties because both of them completely fill the outer shell of their atoms' electrons, so there is nothing to share with other atoms, neither with the same element nor with any other element.
Explanation:
Helium and Neon are both noble gases . As elements react, their atoms, by losing, acquiring, or sharing electrons, complete their outer shells. Noble gas atoms already have full outer shells, so there is no tendency for them to lose, gain, or share electrons. There are incomplete outer shells of atoms of group 1 and 7 elements (so they are reactive)
<u>Chemical properties of HELIUM and NEON -:
</u>
- In group 8(or 0) of the periodic table, on the far right side, the Noble Gases are contained. Helium, neon, argon, krypton, xenon and radon are their names.
- They are extremely colourless and unreactive.
- They do not form bonds, so they still remain as single (monatomic) atoms.
- There is very little chemical reactivity in them.
Hence, helium and neon have similar chemical properties as they are the most stable due to having the maximum number of valence electrons their outer shell can hold.
