complex sentence

A simple sentence consists of only one clause. A compound sentence consists of two or more independent clauses. A complex sentence has at least one independent clause plus at least one dependent clause. A set of words with no independent clause may be an incomplete sentence, also called a sentence fragment.

A simple sentence can be converted into a complex sentence by expanding a word or phrase into a complex sentence. The complex sentence can be a noun clause, adjective clause or adverb clause. Study the example sentences given below. He bought the factory that belonged to his uncle.

Thus a simple sentence can be converted into a compound sentence by expanding a word or phrase into a clause and by using a coordinating conjunction to connect the clauses. More examples are given below: Simple: Being ill, he didn’t attend the party. Compound: He was ill and didn’t attend the party.

Compounds Examples

• Water – Formula: H2O = Hydrogen2 + Oxygen.
• Hydrogen Peroxide – Formula: H2O2 = Hydrogen2 + Oxygen2
• Salt – Formula: NaCl = Sodium + Chlorine.
• Baking Soda – Formula: NaHCO3 = Sodium + Hydrogen + Carbon + Oxygen3
• Octane – Formula: C8H18 = Carbon8 + Hydrogen18

Some common strong Arrhenius bases include:

• Potassium hydroxide (KOH)
• Sodium hydroxide (NaOH)
• Barium hydroxide (Ba(OH)2)
• Caesium hydroxide (CsOH)
• Strontium hydroxide (Sr(OH)2)
• Calcium hydroxide (Ca(OH)2)
• Lithium hydroxide (LiOH)
• Rubidium hydroxide (RbOH)

If it has a proton attached to N,O,S, Se, a halide or has a positive charge it’s an acid. Some are strong some are weak. If it has unshared electron pairs or a negative charge it is a base again some strong, some weak. Anions from strong acids are weak bases.

Note that a compound:

1. consists of atoms of two or more different elements bound together,
2. can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means),
3. has properties that are different from its component elements, and.
4. always contains the same ratio of its component atoms.

Compounds. There are two basic types of compounds. They are distinguished by by the manner in which the atoms bind to one another in the compound. These two types are called “molecular” compounds and “salts” (or equivalently “ionic” compounds):

There are four types of compounds, depending on how the constituent atoms are held together:

• molecules held together by covalent bonds.
• ionic compounds held together by ionic bonds.
• intermetallic compounds held together by metallic bonds.
• certain complexes held together by coordinate covalent bonds.

Compounds are represented by chemical formulas. Elements in a compound are represented by chemical symbols, and the ratio of different elements is represented by subscripts. There are different rules for writing the chemical formulas for ionic and covalent compounds….

A compound is a material composed of two or more components. Water, carbon dioxide and table salt are some examples of compounds.

The following are examples of NOT compounds. Br2 , bromine, is a diatomic element, or a molecular element. Only one element is in its structure though, so it is not a compound. Ar , argon, is an atom; thus, it cannot be multi-atomic, and consequently is not a compound….

Compound Basics A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element.

Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be separated by a chemical reaction. Common examples are water (H2O), salt (sodium chloride, NaCl), methane (CH4). It is possible for a molecule to be an element (e.g. oxygen, O2) or a compound (e.g. water, H2O).

List of Chemical compounds- their common name, formula and uses

Water (H2O) – No explanation is needed as to how important water is in our life. Basically, water is something that could help us survive even if we don’t have anything else. Sodium Chloride or Table Salt (NaCl) – Salt is used not only in cooking, but in cleaning as well.

Empirical Formulas An empirical formula tells us the relative ratios of different atoms in a compound. The ratios hold true on the molar level as well. Thus, H2O is composed of two atoms of hydrogen and 1 atom of oxygen. Likewise, 1.0 mole of H2O is composed of 2.0 moles of hydrogen and 1.0 mole of oxygen….

In the English language, the word “but” is also used for multiple purposes. It can serve as a conjunction, a preposition, an adverb, or a noun in sentences. This word is commonly categorized under conjunctions because it can connect two clauses together and form a single sentence.

‘But’ is a conjunction used to introduce something contrasting with what has already been mentioned. This is fine, except when ‘but’ is used in complex situations where communication is sensitive. For example: in apologies, critique, and other nuanced personal communication.
