If myristic acid is molecular, what is I in the ∆Tf=ikfm equation?

200.0 mL of 0.200 M HNO3 is added to 200.0 mL of 0.200 M KOH in a coffee cup calorimeter. The neutralization reaction that occurs can be described by the chemical equation- HNO3(aq) + KOH(aq) → KNO3(aq) + H₂O(l) Before the solutions are mixed they are both at 23.00 °C. After the mixing of the solutions the temperature increases until it remains constant at 24.39 °C. Assuming no heat lost to the surroundings, how much heat was lost in this reaction? (Assume the specific heats and densities of the solutions is the same as water.)

3.61 g of MgSO₄ is placed into 100.0 mL of water. The water's temperature increases by 6.70°C. Calculate ∆H, in kJ/mol, for the dissolution of MgSO₄. (The specific heat of water is 4.18 J/g･°C and the density of the water is 1.00 g/mL). You can assume that the specific heat of the solution is the same as that of water.

For the part circled, what if the molarity is different and one has a molarity of 3 and one has M=2. When we normalize, are we dividing by the limiting reactant?

When two different liquids are mixed or when a gas or solid is dissolved in a liquid, bondsare broken between neighbouring molecules (or sometimes atom) in the feed materials,and new bonds are formed between neighbouring molecules (or ions) in the productsolution. i. Briefly distinguish between heat of solutions and standard heat of formation of solution.ii. Consider solid X is to be dissolved in solvent Y. If Δ?? °is the heat of formation of X(s),using the appropriate notations, write an equation to calculate the standard heat of formation of solution that contains 5 mol of X in 100 mol of Y at 25°C, relative to X and Y.

When HCI(aq) is added to calcium carbonate solid, carbon dioxide gas, liquid water and aqueous calcium chloride form: CaCO3(s) + 2HCI(aq) → Co,(g) + CaCl,(aq) + H,0(1) This reaction is used by geologists to confirm the presence of limestone (calcium carbonate) in minerals. In this experiment you are trying to determine the effect of concentration of HCI(aq) on the production of carbon dioxide. a. Based upon the information above, come up with a question to answer. (C:1) You can use the following equipment to answer this question: calcium carbonate chips, 1.90 mol/L HCI(aq), pH meter (measures hydrogen ion concentration), beaker, timer, apparatus to measure gas produced b. Based upon the equipment provided above, design a procedure to answer your question. Ensure you provide numbered steps. (1:3, C:2) c. Hypothesize an answer to your question. (I:1) Give reasons for your hypothesis. Ensure you are very specific. (A:3) From your experiment, you collect the following data:

What is the change in enthalpy in joules when 5.44x10-4 mol of AgCl dissolves in water according to the following chemical equation: AgCl(s) → Ag⁺(aq) + Cl⁻(aq) ∆H =65.5 KJ I need the step-by-step process please & thank you!

2 (a) In this investigation, you will use a polystyrene-cup calorimter to determine the amount of heat released during acid-base neutralization reactions. Find information in your textbook, an encyclopedia, or a web site about calorimetry. Sketch the apparatus for a polystrene-cup calorimeter. (b) For more precise heat of reaction measurnments, chemists use a device called bomb calorimeter. How is a bomb calorimeter similar to and different from a polystyrene-cup calorimeter?

Given the reactions, X(s) + O₂(g) — XO(s) XCO3(s) what is AH for this reaction? X(s) + 1/2O₂(g) + CO₂(g) AH = XO(s) + CO₂(g) AH = -545.7 kJ AH = +433.9 kJ XCO3(s) kJ
