Front

What is a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, indicating that mass is conserved during the reaction.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula: a = (final velocity - initial velocity) / time.

How many protons does an atom of Carbon have?

Back

Carbon has 6 protons.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

How many valence electrons does aluminum (Al) have?

Back

Aluminum has 3 valence electrons.

Front

What is the pH scale?

Back

The pH scale measures how acidic or basic a solution is, ranging from 0 (acidic) to 14 (basic), with 7 being neutral.

Front

What is the classification of a solution with a pH of 11?

Back

A solution with a pH of 11 is classified as basic.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula: F = mass (m) x acceleration (a).
