Unit 7 Review Flashcard

Front

What is oxidation?

Back

Oxidation is the loss of electrons.

Front

What type of reaction is represented by the equation @@S_3H_6 ightarrow 3S + 3H_2@@?

Back

The reaction is a decomposition reaction.

Front

What is the coefficient in front of I2 when balancing the equation @@HI ightarrow I_2 + H_2@@?

Back

The coefficient is 1.

Front

What is the oxidation number of iodine in KIO3?

Back

The oxidation number of iodine in KIO3 is +5.

Front

What is reduction?

Back

Reduction is the gain of electrons.

Front

Define a decomposition reaction.

Back

A decomposition reaction is a type of chemical reaction where one reactant breaks down into two or more products.

Front

What is the difference between oxidation and reduction?

Back

Oxidation involves the loss of electrons, while reduction involves the gain of electrons.

Front

What is the general form of a synthesis reaction?

Back

A synthesis reaction has the general form A + B → AB, where two or more reactants combine to form a single product.

Front

What is the oxidation state of an element in its elemental form?

Back

The oxidation state of an element in its elemental form is 0.

Front

What is the purpose of balancing chemical equations?

Back

Balancing chemical equations ensures that the law of conservation of mass is followed, meaning the number of atoms of each element is the same on both sides of the equation.
