What is the difference between a compound subject and a compound predicate?

What is the difference between a compound subject and a compound predicate?

Definition: A sentence has a compound subject when it has more than one subject. It has a compound predicate when there is more than one predicate. A compound predicate might share a helping verb, or it might be two (or more) separate verb phrases.

Can a compound sentence have two subjects?

Typical sentence constructs follow a subject + verb + direct object formula. When a sentence has two or more subjects, it’s called a compound subject. Compound subjects are joined by “and” or “or” and, perhaps, a series of commas.

How do you know if a sentence is a compound?


  1. If two clauses are connected with a coordinating conjunction, it’s a compound sentence.
  2. If two clauses are connected with a subordinating conjunction, it’s a complex sentence.

Is they a compound subject?

When a sentence has two or more subjects, that’s called a compound subject. The individual subjects are joined by a coordinating conjunction (like and, or, neither, or nor). When the subjects are joined by “and,” the verb agrees with the pronoun “they.”

What is an example of a compound object?

Compound direct objects are two or more direct objects receiving the action of the same action verb. Trisha bought a jacket and a scarf.

Can a sentence have a compound direct object?

A sentence can still have two direct objects and not contain a compound direct object. When the two direct objects are acted on by different verbs, they are just direct objects. An example of a sentence with two direct objects but no compound direct objects is: Mary saw the D.O.

What is a compound subject and object?

A subject or an object of a sentence is compound if it describes 2 or more things or people. Examples. Compound Subjects. Mary and Jane went to the same school. In this sentence the subject describes 2 people, so it is a compound subject.

What is compound subject in grammar?

A compound subject is two or more individual noun phrases coordinated to form a single, longer noun phrase. Compound subjects cause many difficulties in the proper usage of grammatical agreement between the subject and other entities (verbs, pronouns, etc.).

What is a compound simple subject?

A compound subject is a subject with two or more simple subjects. In a compound subject, the simple subjects are joined by words like “and,” “or,” or “nor” (called coordinate conjunctions) or pairings like “either/or” and “neither/nor” (called correlative conjunctions).

What is a compound sentence?

A compound sentence consists of two or more independent clauses joined with a comma and coordinating conjunction, also known as the FANBOYS (for, and, nor, but, or, yet, so). In addition, you can join independent clauses with a semicolon or with a semicolon, conjunction adverb, and a comma.

Whats is a compound?

A compound is a material formed by chemically bonding two or more chemical elements. The type of bond keeping elements in a compound together may vary: covalent bonds and ionic bonds are two common types. The elements are always present in fixed ratios in any compound.

What are the 10 compounds?

List of Chemical Compounds and their uses

  • Calcium Carbonate.
  • Sodium Chloride.
  • Methane.
  • Aspirin.
  • Potassium Tartrate.
  • Baking soda.
  • Acetaminophen.
  • Acetic Acid.

Is O2 a compound?

The oxygen molecule O2 is considered a molecule but not a compound.

Can a compound be broken down?

Compounds can be decomposed by chemical means into elements or simpler compounds. Water is broken down into hydrogen and oxygen by electrolysis.

What are two ways to break down a compound?

Answer Expert Verified. Photolysis and hydrolysis. These are two methods that can be used to break down a compound into simpler substances and smaller units. Water which is used to break the bonds of molecules and split molecules is used from hydrolysis.

What methods are used to break down compounds?

Methods of Breaking Down Compounds The only way to break down a compound is through a chemical change. Sometimes, energy is needed for a chemical change to happen. Two ways to add energy to break down a compound are to apply heat and to apply an electric current.

Can a compound be broken down by filtration?

Explanation: Filtration works best when the solute isn’t dissolve in the solvent. For instance, sand and water can be seperate through filtration as both compounds do not dissolve with each other. However, sugar and water would not be seperated through filtration as they dissolve with each other.

Can a compound be separated by physical means?

A compound is a pure substance composed of two or more different atoms chemically bonded to one another. That means that it can not be separated into its constituents by mechanical or physical means and only can be destroyed by chemical means.

What is the difference between an element and a compound?

An element is made up of one type of atom only. For example, a piece of pure copper is made up of only of copper atoms. A compound is a substance made up of two or more atoms of different elements chemically joined (or bonded) together.

What is the difference between a mixture and a compound?

Compound:a substance that is made up of more than one type of atom bonded together. Mixture: a combination of two or more elements or compounds which have not reacted to bond together; each part in the mixture retains its own properties.

What is true of a compound?

Two things are true of all compounds: A compound always has the same elements in the same proportions. For example, carbon dioxide always has two atoms of oxygen for each atom of carbon, and water always has two atoms of hydrogen for each atom of oxygen. A compound always has the same composition throughout.

What does the chemical formula of a compound indicate?

A chemical formula identifies each constituent element by its chemical symbol and indicates the proportionate number of atoms of each element. In empirical formulae, these proportions begin with a key element and then assign numbers of atoms of the other elements in the compound, by ratios to the key element.

Which substance is a compound Why?

A compound is a unique substance that consists of two or more elements combined in fixed proportions. This means that the composition of a compound is always the same. The smallest particle of most compounds in living things is called a molecule. Consider water as an example.

What are the 4 types of compounds?

Types of Compounds

  • Metal + Nonmetal —> ionic compound (usually)
  • Metal + Polyatomic ion —> ionic compound (usually)
  • Nonmetal + Nonmetal —> covalent compound (usually)
  • Hydrogen + Nonmetal —> covalent compound (usually)

What is a complete predicate example?

The complete predicate of a sentence tells what the subject does or is. It includes a verb and all other details that describe what is going on. example: My father fixed the dryer. The simple predicate is the main verb in the predicate that tells what the subject does.
