CHEM 1411: General Chemistry II

Learn how to compute the freezing point of water at various solution concentrations using the freezing point depression formula. Uncover the relationship between concentration and the lowered freezing points for four distinct solutions. Equip yourself with essential knowledge on the effects of solute concentration on water's freezing behavior.

Exploring the titration of 25.00 mL of 0.08230 M KI with 0.05110 M AgNO3. This video breaks down the calculation process for the potential of silver ion at various volumes of added AgNO3: 39.00 mL equivalence point and 44.30 mL. With clear steps and using the solubility product constant understand how the potential of silver ion is determined for each scenario.

Explore how to calculate the theoretical yield of TiCl? in moles based on different initial quantities of reactants in the chemical equation Ti + 2 Cl? ? TiCl?.

We explore the impact of increasing the concentration of ethylene glycol in an antifreeze mixture, explaining the resulting effect on the freezing point of the solution by examining its interaction with water molecules.

In this video, we classify substances as elements, compounds, or mixtures, with air and soy sauce as mixtures, iron as an element, and table salt as a compound.

In this video, the problem involves calculating the mass of magnesium oxide (MgO) produced when 14.8 liters of oxygen gas react with magnesium metal according to the chemical equation 2Mg + O2 -> 2MgO. The stoichiometric relationship is used to determine that 0.6607 moles of oxygen gas results in 1.3214 moles of MgO, with a final calculation yielding a mass of 53.25 grams of MgO formed during the reaction at Standard Temperature and Pressure (STP).
