Question 1

Inorganic nomenclature

Answer 1

• Set of rules used to name inorganic compounds. IUPAC is the highest chemical nomenclature authority
• Inorganic compounds are classified according to their chemical function in oxides, bases, acids, and salts.

There are three types of valid nomenclatures: Stoichiometric, stock and traditional

Answer 2

Binary

Ternary

Question 3

Binary

Answer 3

• Metal+Oxygen- metal oxides- Na²O, Fe²O³
• Nonmetal+oxygen- nonmetal oxides(Anhydrides)-NO³, CO²
• Metal+nonmetal- binary salts- NaCl, FeBr³
• Metal+hydrogen- Metal hydrieds- AuH³,PbH⁴
• Hydrogen+Nonmetal- Nonmetal hydrieds- HCl, H²S

Question 4

Ternary

Answer 4

• Metal+Polyatomic- Oxysalts- Na²SO⁴, Al²(CO²)³

Question 12

Chemical reactions

Answer 12

nvolves a transformation at an atomic level.
-Process in which one or more substances (elements or compounds), the reactants, are converted to different substances (rearranging the constituent atoms of the reactants), the products (one or more).

Question 13

How can you represent a chemical reaction?

Answer 13

by using formulas and symbols. These formulas and symbols constitute a chemical equation.

Question 14

What is on the left side of the arrow of the formulas,

Answer 14

Formulas of the initial substances known as reactants or reagents

Question 15

What is on the right side of the atom of the formula

Answer 15

The final substances, known as products

Question 16

What is a catalyst

Answer 16

a substance that accelerates or slows down a chemical reaction

Question 17

What do the letters (g), (l), and (s) mean?

Answer 17

The substances are in the gas, liquid, or solid phase, respectively.

Question 18

what does the letter (aq) mean?

Answer 18

aqueous state

Question 19

Combustion

Answer 19

Oxygen combines with a substance producing carbon dioxide and water and releasing energy as heat or light.

Question 20

Synthesis

Answer 20

Two or more substances get together to form a new compound.

A+B=AB

Question 21

Decomposition

Answer 21

Compound that decomposes and forms new substances.

AB=A+B

Question 22

Simple displacement

Answer 22

An element takes another element from a compound.

AB+C=AC+B

Question 23

Double displacement:

Answer 23

Two elements take other elements from different compounds.

AB+CD=AC+BD
