Front

Bonds formed by sharing electrons between atoms are called?

Back

Covalent bonds.

Front

What type of substance is an excellent conductor of electricity in both solid and molten states, and is malleable and ductile?

Back

Metallic substance.

Front

What is the term for the maximum amount of product that could be obtained in a chemical reaction?

Back

Theoretical yield.

Front

Calculate the molar mass for Al(OH)3. What is the result?

Back

78.0 g/mol.

Front

What type of reaction is represented by the equation: Zn + 2HCl → ZnCl2 + H2?

Back

Single Replacement reaction.

Front

What is the definition of ionic bonds?

Back

Ionic bonds are formed when electrons are transferred from one atom to another, resulting in the formation of charged ions.

Front

What is the difference between actual yield and theoretical yield?

Back

Actual yield is the amount of product obtained from a reaction, while theoretical yield is the maximum amount predicted based on stoichiometry.

Front

What is a mole ratio?

Back

A mole ratio is a conversion factor derived from the coefficients of a balanced chemical equation, used to relate the amounts of reactants and products.

Front

What is the definition of molar mass?

Back

Molar mass is the mass of one mole of a substance, typically expressed in grams per mole (g/mol).

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product.
