FLASHCARD QUESTION

Front

What is the formula to calculate the dilution of a solution?

Back

The dilution formula is: \(C_1V_1 = C_2V_2\), where \(C_1\) is the concentration of the stock solution, \(V_1\) is the volume of the stock solution needed, \(C_2\) is the concentration of the diluted solution, and \(V_2\) is the total volume of the diluted solution.

FLASHCARD QUESTION

Front

Which molecule does not have resonance structures?

Back

Water (H2O) does not have resonance structures.

6.

FLASHCARD QUESTION

Front

Define molarity (M).

Back

Molarity (M) is defined as the number of moles of solute per liter of solution: \(M = \frac{n}{V}\), where \(n\) is the number of moles and \(V\) is the volume in liters.

FLASHCARD QUESTION

Front

What is the significance of resonance structures in chemistry?

Back

Resonance structures represent different ways of arranging electrons in a molecule, indicating that the actual structure is a hybrid of these forms, which can affect stability and reactivity.
