Obtain a box of breakfast cereal and read the list of ingredients. What are four chemicals from the list? a. monoglycerides. b. cocamide DEA. c. folic acid. d. iron. e. chromium ion. f. peroxide. g. lauryl glucoside. h. disodium phosphate.

The options are a, c, d and h

Explanation:

The following ingredients can be found in a packaged food cereal

Monoglycerides are used as emulsifiers and they are also added to cereals to improve there texture and shelf-life.

Folic acid or folate is a vitamin that most cereals are fortified with to act as dietary supplement.

Iron is an essential mineral element, meaning your body needs it (basically for  blood production). Cereals are usually fortified with iron for this reason.

Disodium phosphate is also a food additive used to improve the quality of food and is also found in cereals.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
