Answer:
1.666
≈ 1.67 g/cm³
Explanation:
Mass = 200g
Length = 6cm
Width = 4cm
Height = 5cm
Density = Mass/ Volume
Volume = length×width×height
Density =
The process of chemical weathering by oxygen and water on iron is known as rusting........rust is a loose reddish brown layer of hydrated ferric oxide(Fe2O3.H2O)
Answer:
Chemical energy
Explanation:
Energy in carbohydrates is stored as chemical energy which is released when the carbohydrate is broken down by the body to give glucose and ATP. Animals eat carbohydrates as energy molecules from which they derive energy from the stored chemical energy.

Answer:
A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It's also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other. The terms "molecule" and "compound" mean the same thing and can be used interchangeably.
Sometimes confusion arises because the definitions of molecule and compound haven't always been so clear-cut. In the past, some schools taught that molecules consisted of atoms bonded via covalent chemical bonds, while compounds were formed via ionic bonds. The hydrogen and oxygen atoms in water are covalently bonded, so under these older definitions, water would be a molecule but not a compound. An example of a compound would be table salt, NaCl. But, as scientists came to understand chemical bonding better, the line between ionic and covalent bonds became fuzzier. Also, some molecules contain both ionic and covalent bonds between the various atoms.
In summary, the modern definition of a compound is a type of molecule consisting of at least two different types of atoms. By this definition, water is both a molecule and a compound. Oxygen gas (O2) and ozone (O3), for example, are substances that are molecules but not compounds.
