What is Charles' Law?

Back

Charles' Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) when pressure is held constant. Mathematically, it is expressed as V1/T1 = V2/T2.

How many moles of oxygen are produced when 6.7 moles of KClO3 decompose completely?

Back

10.1 moles of oxygen are produced.

What is a positively charged subatomic particle?

Back

A proton is a positively charged subatomic particle found in the nucleus of an atom.

Front

What is a subatomic particle with no charge?

Back

A neutron is a subatomic particle with no charge, also found in the nucleus of an atom.

Front

For a solution at 25°C, what is the relationship between pH and pOH?

Back

At 25°C, pH + pOH = 14.

Front

What is the equation for Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when temperature is held constant. Mathematically, it is expressed as P1V1 = P2V2.

Front

What is the definition of molarity?

Back

Molarity is a measure of concentration, defined as the number of moles of solute per liter of solution (mol/L).

Front

What is the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

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; it is conserved.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.
