What is a Balanced Chemical Equation (BCE)?

Back

A Balanced Chemical Equation (BCE) shows the reactants and products of a chemical reaction with equal numbers of each type of atom on both sides, ensuring the law of conservation of mass is followed.

Front

What is the right ratio of chemicals for the BCE: CO + Fe2O3 --> Fe + CO2?

Back

3,1 --> 2,3

Front

What ion is more present in a basic solution?

Back

OH- (hydroxide ion) is more present in a basic solution.

Front

At what temperature can you fully dissolve 60g of KNO3?

Back

37 degrees Celsius.

Front

How would potassium bromide be described if 80 grams is dissolved in 100 mL of water at 10 degrees?

Back

Supersaturated.

Front

What are electrolytes?

Back

Electrolytes are substances that dissociate into ions in solution and can conduct electricity.

Front

Which of the following are electrolytes? Acids, Bases, Salts, or All?

Back

All.

Front

What is the definition of saturation in a solution?

Back

Saturation occurs when a solution can no longer dissolve additional solute at a given temperature and pressure.

Front

What is the difference between a saturated and a supersaturated solution?

Back

A saturated solution contains the maximum amount of solute that can dissolve at a given temperature, while a supersaturated solution contains more solute than can normally dissolve.

Front

What is the role of temperature in solubility?

Back

Generally, increasing temperature increases the solubility of solids in liquids, but decreases the solubility of gases.
