Front

What is a property of true metals?

Back

True metals are typically malleable, shiny, and conductive, but they are not brittle.

Front

Which element is a p block element?

Back

Argon (Ar) is a p block element.

Front

What is a mole in chemistry?

Back

A mole is a large number used to count particles, specifically 6.022 x 10^23 particles.

Front

How many molecules are in 1 mole of any substance?

Back

1 mole of any substance contains 6.022 x 10^23 molecules.

Front

How do you calculate the mass of a substance from moles?

Back

Mass (g) = Moles x Molar Mass (g/mol).

Front

What is the molar mass of copper (I) chromate, Cu2(CrO4)?

Back

The molar mass of Cu2(CrO4) is approximately 267.00 g/mol.

Front

If you have 0.11 moles of copper (I) chromate, how do you find the mass?

Back

Mass = 0.11 moles x 267.00 g/mol = 26.74 g.

Front

What is the difference between a physical property and a chemical property?

Back

A physical property can be observed without changing the substance's identity, while a chemical property describes a substance's ability to undergo a chemical change.

Front

What is malleability?

Back

Malleability is the ability of a material to be deformed under compressive stress, often characterized by the material's ability to form a thin sheet.

Front

What does it mean for a metal to be conductive?

Back

Conductivity refers to the ability of a material to conduct electricity or heat.
