Where do we get all of our simple and complex carbohydrates from

Chemistry
1 answer:
7nadin3 [17]3 years ago
7 0

Answer & explanation:

Carbohydrates (both simple and complex) are found in all plant foods, due to the fact that plants produce them during <u>photosynthesis</u> and use carbohydrates as their energy source.

Some examples of carbohydrate rich foods are corn, rice, potatoes and pasta as well. Honey and dairy foods also have carbohydrates.

Carbohydrates also have structural function, such as cellulose, which is the main component of plant cell walls, and chitin, which can be found in the atropod exoskeleton.

Precipitation calculations with Ni2+ and Pb2+
Maurinko [17]

Precipitation calculations with Ni²⁺ and Pb²⁺ a. Use the solubility product for Ni(OH)₂ (s) . the pH at which Ni(OH)₂ begins to precipitate from a 0.18 M Ni²⁺ solution. (Ksp Ni(OH)₂ = 5.5x10⁻¹⁶) is 6.8.

When Ni(OH)₂ starts precipitate :

Ksp of Ni(OH)₂ = [ Ni²⁺ ] [ OH²⁻ ]

5.5x10⁻¹⁶ = [ 0.18 ] [ OH²⁻ ]

[ OH²⁻ ] = 5.5x10⁻¹⁶ / 0.18

[ OH⁻ ] = 5.5 × 10⁻⁸ M

pOH = 7.2

therefore , pH = 14 - 7.2

                  pH = 6.8

Thus, Precipitation calculations with Ni²⁺ and Pb²⁺ a. Use the solubility product for Ni(OH)₂ (s) . the pH at which Ni(OH)₂ begins to precipitate from a 0.18 M Ni²⁺ solution. (Ksp Ni(OH)₂ = 5.5x10⁻¹⁶) is 6.8.

Help pleaseeeeeeeee 30 points
sineoko [7]

It is about who you are. Just write down anything that relates to you. This is not difficult at all. This worksheet just wants you to fill out your strengths, weaknesses, motivations and personal goals.

All I can say is to write about yourself.
