Describe the components of a molecule whose atoms are joined by covalent bonds.
kipiarov [429]

Answer:

nonmetal

Explanation:

In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

What are the reactants and products of a redox reaction, neutralization reactions, and precipitation reactions?
Virty [35]

Answer:

Precipitation reactions are ones in which at least one of the reactants is in the aqueous phase (i.e., dissolved in water), and a solid forms on the product side which was not present on the reactant side. If all the reactants are solid, then a solid product forming should not be called a precipitate. To be called a precipitate, an insoluble product must form from within solution, either from a solid and solute interacting, or from an interaction strictly between solutes.

Subspecies: In biological classification, the term subspecies refers to one of two or more populations of a species living in different subdivisions of the species' range and varying from one another by morphological characteristics. ... In the wild, subspecies do not interbreed due to geographic isolation or sexual selection

Arthropod: Arthropoda, such as an insect, spider, or crustacean.

Micrometer: an instrument used with a telescope or microscope for measuring very small distances. 2 : an instrument having a rod moved by fine screw threads and used for making exact measurements. micrometer.

Hypothermia: Hypothermia is a potentially dangerous drop in body temperature, usually caused by prolonged exposure to cold temperatures. The risk of cold exposure increases as the winter months arrive. But if you're exposed to cold temperatures on a spring hike or capsized on a summer sail, you can also be at risk of hypothermia.

Polymorph: Polymorphism is the ability of a substance to crystallize into different crystalline forms. These crystalline forms are called polymorphs or crystalline modifications. Polymorphs have the same liquid or gaseous state but they behave differently in the solid state.
