Arnold kept a water log as a project for his chemistry class. Arnold's family consists of Arnold, his sister, and his parents fo

r a total family size of four. He measured each family member's water usage every day for a week, and found that the family used an average of 457 gal/day. Arnold's city charges $0.223/cgal of water. The unit centigallon (cgal) is used by cities to measure the volume of water used, where 1 cgal is equal to 100 gal. Assuming this average usage continues, how much does Arnold expect his family to pay in a year for water usage?

Answer:

$ 1487.90 .

Explanation:

Family size = 4

Water usage per member = 457 gal / day .

Water usage for whole family = 457 x 4

Use of water in one year for family = 457 x 365 x 4 = 667220 gal

667220 gal = 667220 / 100 = 6672.20 cgal .

expense per cgal = $ 0.223

Total yearly expected expense = 0.223 x 6672.20

= $ 1487.90

Use the drop-down menus to identify each substance as an organic or inorganic compound
dalvyx [7]

Answer:

ozone (O3): inorganic

methane (CH4): organic

aluminum hydroxide (Al(OH)3): inorganic

butane (C4H10): organic

carbon monoxide (CO): inorganic

Explanation:

An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. Some simple compounds that contain carbon are often considered inorganic. Examples of inorganic compounds include carbon monoxide , carbon dioxide , carbonates, carbides , cyanides, cyanates, and thiocyanates. Most of these compounds are normal parts of mostly organic systems, including living organisms. When a chemical substance is classified as inorganic, it does not necessarily mean that it does not occur within

living things.

Organic compounds typically contain the carbon-hydrogen bonds. The carbon atoms often catenate and most organic substances occur in living systems and are products of biochemical reactions in living organisms. However, organic substances can also be synthetic and can be prepared in the laboratory.
