PS9 Chemistry Final Prep (Part 4)

Front

What is an ionic lattice?

Back

An ionic lattice is a rigid structure formed by the regular arrangement of anions and cations in a precise pattern, which gives shape to ionic compounds like table salt.

Front

What happens during an exothermic reaction?

Back

In an exothermic reaction, bonds are formed, and energy is released.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings, often in the form of heat.

Front

What states of matter can covalent substances exist in at normal atmospheric temperature and pressure?

Back

Covalent substances can exist as solids, liquids, and gases.

Front

What does the law of conservation of mass state?

Back

The law of conservation of mass states that in a chemical reaction, the mass of the reactants is equal to the mass of the products.

Front

Define cation.

Back

A cation is a positively charged ion that is attracted to anions in ionic compounds.

Front

Define anion.

Back

An anion is a negatively charged ion that is attracted to cations in ionic compounds.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that leads to the transformation of one set of chemical substances into another.

Front

What is the significance of energy changes in chemical reactions?

Back

Energy changes indicate whether a reaction is exothermic (releases energy) or endothermic (absorbs energy), affecting reaction conditions and product stability.
