1. When, a volume of 200 cm³ of Lithium hydroxide solution of concentration 1.00 mol/dm³ and 200 cm³ of Hydrochloric acid of concentration 100 mol/dm³ were mixed together in a calorimeter the reaction was investigated to be exothermic. a) Distinguish between endothermic and exothermic reactions. b) Based on the information given above in question one (1), calculated the enthalpy change per mol of water produced, if the heat capacity of the calorimeter was 76 J/K and the temperature rise was 5.25 K. (State any assumptions made)
Identify the correctly written "formation reaction" among the following reactions. Hint: Recall the definition of a "formation reaction". O 2H2 (g) + 02 (g)→ 2H20 (1) N2 (g) + O2 (g) → 2NO (g) O 2H2 (g) + 02 (g)→ 2H20 (g) 2C (s. graphite) + 2H2(g) → C2H4 (g) H20 () + 1/2 02 (g) → H202 (1)
Do the follow reactions depict Heat of Formation Reactions? If so, mark the reaction as YES, if it is not a Heat of Formation Reaction, then choose NO. ✓3/2 H₂(g) + P(s) → PH3(g) H₂(g) + 1/2O₂(g) → H₂O(g) Al(s) + 3/2 Br₂(1)→ AlBr3(S) Na(s) + H₂O(1)→ NaOH(aq) + 1/2 H₂(g) ✓2As(s) + 5/2 O₂(g) → As2O5(s) In formation reactions the reactants must be elements in their most common states, and the only product is one mole of the substance of interest.

Dry ice is solid carbon dioxide. Instead of melting, solid carbondioxide sublimes according to the equation:CO2(s) ------------>CO2(g) When dry ice is added to warm water, heat from the water causesthe dry ice to sublime more quickly. The evaporating carbon dioxide produces a dense fog often used to create special effects. In a simple dry ice fog machine, dry ice is added to warm water in a Styrofoam cooler. The dryice produces fog until it evaporates away, or until the water gets too cold to sublime the dry ice quickly enough. A small Styrofoam cooler holds15.0 L of water heated to 85°C. Use standard enthalpies of formation to calculate the change in enthalpy for dry ice sublimation, and calculate themass of dry ice that should be added to the water so that the dry ice completely sublimes away when the water reaches 25 °C. Assume no heat loss to the surroundings. (The ∆H°f for CO2(s) is -427.4 kJ/mol.) How do I do this?
A reaction between Mg and aqueous hydrochloric acid was performed to determine the heat of the reaction. A calorimeter with a heat capacity of 6.5 J/K was used. To the calorimeter 50.0 mL of 1.0 M HCI was added, the initial temperature was recorded and then 0.250 g of magnesium metal was added. The final temperature was then recorded. (Assume density of the solution is 1.03 g/mL; q = MCAT ; molar mass Mg = 24.31 g/mol; specific heat capacity of water = 4.184 J/g.K; q calorimeter = heat capacity x AT). The following data was recorded:Initial temperature:21.5°c ; Final Temperature: 45.1°c Calculate calorimeter (J) q solution (J) total amount of heat released (J), mol Mg, enthalpy of reaction in kJ/molor (q total/mol Mg). Just put the numerical values since units are already indicated. For the question, amount of heat released, there is no need to put the negative sign.
