Gold is malleable while glass, pottery, and ice are not.
Malleability is the ability of a material to be hammered or rolled into thin sheets without breaking. Gold is highly malleable and can be shaped into various forms, such as jewelry and gold leaf. Glass, pottery, and ice, on the other hand, are not malleable because they will break or shatter when hammered or rolled into thin sheets.
Gold is malleable because its metallic bonds allow its atoms to slide past one another without breaking. Glass, pottery, and ice lack these bonds and have a more rigid structure, making them non-malleable. Instead, glass and pottery are brittle, while ice can fracture under stress due to its molecular structure.

A form of electricity which can attract things is static electricity. Static electricity is the result of an imbalance between negative and positive charges in an object. These charges built up o the surface of an object until they find a way to e released or discharged causing the attraction of things.

The answer is: four.
For example compound carbon dioxide (CO₂):
Electron configuration of carbon: ₆C 1s² 2s² 2p².
Electron configuration of oxygen: ₈O 1s² 2s² 2p⁴.
Carbon atom is sp2 hybridized, it has three sp2 orbitals and one p orbital, they form four bonds.
Oxygen has two p orbitals, they form two bonds (one sigma and one pi bond).
p orbitals from carbon and oxygen overlap and form pi bond.
Answer:
Functional group
Explanation:
Functional group is specific group of atom or bond associated to an organic compound that determines the chemical properties of that compound. This atom is bonded in a certain way or specific arrangement to give the compound a peculiar physical and chemical characteristics.
Functional group like the alkyl group -CH3 is found in organic compound series like the alkane family. The chemical properties specific to the alkyl group will be active in the compound of alkane family because of the presence of the functional group Alkyl(-CH3). The functional group also plays a major role in the chemical reactivity of the compound. For example the functional group of alkyl are often non reactive, this non reactive nature will definitely rub off on the chemical properties of the compound it is attached.
Functional group like -OH is usually found in Alcohol . Due to the presence of this functional group (-OH) alcohol possess a peculiar chemical properties. The compounds possess an hydrogen bond which invariably lead to the higher boiling points of the alcohol compounds. Other functional group can be bonds like double bond found in alkene compound or triple bond found in alkyne compound.
b. oxygen
c. water
d. carbon dioxide
Answer:
A) milk
Explanation:
Pure substances are materials that have constant chemical composition and physical and chemical properties as they do not change at constant pressure and temperature. Examples of pure substances are oxygen, water and carbon dioxide.
On the other hand, there are compound substances, which unlike simple substances are chemical compounds formed by atoms of different chemical elements, such as milk that is formed from elements from the blood of the animal and contains amino acids, fatty acids. , lactose and certain minerals.
Milk is the only option that is not a pure substance.
In this question, all the options are actually examples of pure substances except for milk. A pure substance is one that is made up of only one type of particle and cannot be separated into simpler substances by physical means. Milk, on the other hand, is a mixture of various components including water, proteins, fats, and sugars.
