Answer: Option (b) is the correct answer.

Explanation:

When two or more atoms of different elements are chemically combined together in similar composition then the product formed is known as a compound.

For example, NaCl is an ionic compound.

Mixture is the substance in which two or more different components are mixed together in different composition. Components of a mixture never combine chemically.

For example, mud in water is a mixture.

Atom is defined as a single molecule of an element. For example, Na (sodium) atom.

A colloid is defined as a mixture in which insoluble particles are microscopically dispersed and suspended throughout another substance.

For example, milk is a colloid.

Therefore, we can conclude that compounds are two or more elements that have been chemically combined.

12. If a solution has a pH of 3, what would the pOH value of that solution be? *
butalik [34]

Answer:

The correct answer is pOH= 11

Explanation:

From the aqueous acid-base equilibrium we know that

pH + pOH = 14

If we know pH, we can calculate pOH as follows:

pOH = 14 - pH

In this problem, the solution has a pH of 3, so:

pOH = 14 - 3 = 11

A compound accepts electrons from another substance to form a covalent bond. Which term best describes this compound’s behavior?
Cloud [144]

A compound accepts electrons from another substance to form a covalent bond. The compound acts as a Lewis base.

<h3>What are the most common acid-base theories?</h3>
  • Arrhenius: acids release H⁺ and bases release OH⁻.
  • Bronsted-Lowry: acids donate H⁺ and bases accept H⁺.
  • Lewis: acids accept electrons and bases donate electrons.

A compound accepts electrons from another substance to form a covalent bond. Which term best describes this compound’s behavior?

  • Lewis acid. YES.
  • Arrhenius base. NO, because OH⁻ is not involved.
  • Bronsted-Lowry acid. NO, because H⁺ is not involved.
  • Bronsted-Lowry base. NO, because H⁺ is not involved.

Write the general chemical formula for an acid, and discuss what each component of the formula represents.
saul85 [17]
The general formula of an acid is HX where H+ acts as the cation while X can be a halogen (Cl-, Fl-, Br-, etc) and acts as the anion. There are also cases where X is an ion like SO42-, which brings two atoms of H in the formula. Strong acids dissociate completely while weak acids do not.
