QA2 Review

Front

What is the pH level of a strong base?

Back

A strong base has a pH level of 14.

Front

What is the relationship between mass and acceleration when a constant force is applied?

Back

According to Newton's second law, acceleration is inversely proportional to mass. Therefore, if two objects are thrown with the same force, the one with greater mass will have less acceleration.

Front

What does Newton's third law state?

Back

Newton's third law states that for every action, there is an equal and opposite reaction.

Front

Which wave has the longest wavelength?

Back

Wave 1 has the longest wavelength.

Front

Is the equation Al + O2 -> Al2O3 balanced or unbalanced?

Back

The equation is unbalanced.

Front

What is the definition of a base in chemistry?

Back

A base is a substance that can accept hydrogen ions (protons) or donate electron pairs.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula a = F/m, where F is force and m is mass.

Front

What is the definition of wavelength?

Back

Wavelength is the distance between successive crests of a wave.

Front

What is the significance of a balanced chemical equation?

Back

A balanced chemical equation indicates that the number of atoms for each element is the same on both sides of the equation, conserving mass.

Front

What is the definition of force in physics?

Back

Force is an interaction that causes an object to change its velocity, which can include starting, stopping, or changing direction.
