Semester-1 Review

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m)

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What is the principle of conservation of mass in a chemical reaction?

Back

The mass of the reactants equals the mass of the products.

Front

What is a chemical reaction?

Back

A process where substances (reactants) transform into new substances (products) with different properties.

Front

What is the atomic number of an element?

Back

The number of protons in the nucleus of an atom, which determines the element's identity.

Front

Identify the element with atomic number 12.

Back

Magnesium (Mg)

Front

What is a precipitate in a chemical reaction?

Back

A solid that forms and settles out of a liquid mixture during a chemical reaction.

Front

How do you calculate net force?

Back

Net Force = Total Forces acting on an object (considering direction).

Front

What is the relationship between mass and acceleration in Newton's second law?

Back

The greater the mass of an object, the less acceleration it will have when a given force is applied.

Front

What happens to the color of zinc when it reacts with CuSO4?

Back

A dark solid (precipitate) forms on the zinc metal, indicating a chemical reaction.
