What is true about elements and compounds elements contain two or more compounds conpounds contain two or more elements compound
statuscvo [17]

Answer:

Taking into account the concepts presented in chemistry with respect to elements and compounds, it is possible to affirm that the compounds are formed by two or more elements.

Explanation:

Two or more chemical elements have the ability to bind -by forming bonds- to obtain a compound. This occurs randomly in nature.

The bonds between the elements that form a compound must be stable enough to ensure the stability of the molecule. A chemical compound can only be separated into the elements that form it by chemical processes.

The bonds types that form compounds can be:

  • <em>Ionic bond.</em>
  • <em>Covalent bond.</em>
  • <em>Coordinated covalent bond.</em>
  • <em>Metallic bond.</em>

It is necessary to mention that chemical elements are called atoms, and the bonds between them are molecules. The physical and chemical properties of a compound will be different from the properties of the elements that form it.

Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells because

Capillaries are tiny blood vessels in the circulatory system that connect aterioles to venules. They are the most abundant or they are much blood vessels. They can penetrate the tissues of the body which allow passage of food nutrients, oxygen in the body thereby allowing exchange of nutrients and oxygen between the body tissues and the blood.

Capillaries surrounding the brain have no pores and are surrounded by membranes of astrocyte cells while capillaries in the periphery Capillaries surrounding the brain have pores and are not surrounded by membranes of astrocyte cells.

Do you think rain amounts can affect soil type?
Zielflug [23.3K]
Yes, I do think so. I believe the rain can break up the soil depending on the type of soil as well as rain amounts. If it doesn't rain much in California their soil might be dry and brittle, but id it rains in South Carolina theirs might by softer and moist.
