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.

How would you prepare 500 mL of 0.360 M solution of CaCl2 from<br> solid CaCl2?

LenKa [72]

We need to measure 20.0 grams of CaCl₂ to prepare 500 mL of 0.360 M solution.

First, we need to determine the required moles of CaCl₂. We have 500 mL (0.500 L) of a 0.360 M solution (0.360 moles of CaCl₂ per liter of solution).

$0.500 L \times \frac{0.360mol}{L} = 0.180 mol$

Then, we will convert 0.180 moles to grams using the molar mass of CaCl₂ (110.98 g/mol).

$0.180 mol \times \frac{110.98g}{mol} = 20.0 g$

To prepare the solution, we weigh 20.0 g of CaCl₂ and add it to a beaker with enough distilled water to dissolve it. We stir it, heat it if necessary, and when we have a solution, we transfer it to a 500 mL flask and complete it to the mark with distilled water.
