A typical recipe for a hot toddy (a drink often used as a cold remedy) is to mix hot water withwhiskey, honey, and lemon juice. A patient heats 16 oz. of 22 C water on the stove until it hasabsorbed 33 kcal of energy. He then mixes 2.0 oz. of the hot water with 1.5 oz. of roomtemperature whiskey (d = 0.94 g/cm3, cs = 3.40 J/g C, T = 22 C). What is the temperature of the hot toddy (prior to adding the remaining ingredients)?

During an experiment a student mixed two chemicals together and noted that the beaker felt warm to the touch after the reaction was complete. In the experiment, the chemicals would be classified as the From this observation, the student concluded that the reaction was A. Which of the following energy pathway diagrams represents the chemical reaction from the student's experiment? Ep (kJ) Select one: OA OB 150 125 100 + and the beaker would be classified as the Reaction Coordinate and that the resulting change in enthalpy (AH) would have a B. 125 E 100 Reaction Coordinate Ep (kJ) 150 ◆ value.

Suppose you burn a 2.4 g sample of potato chips. You use the heat given off from that process to heat 26.5 g of water from 17.7 oC to  20.2  oC. What is the caloric value (in kcal/g) of the potato chips?

A certain reaction has Ho = -43.40 kJ and So = 23.20 J/K.(a) Is this reaction exothermic, endothermic or isothermic (neither)?This reaction is________      .(b) Does this reaction lead to a decrease, an increase, or no change in the degree of disorder in the system?This reaction leads to_______      in the disorder of the system.

2. A patient receives 2.5 L of intravenous (IV) glucose solution. If the liquid contains 5.0 g glucose per 100.0 mL of solution, then calculate the number of kilocalories that the patient receives from the glucose solution. Note, the caloric value of glucose is 4 kcal/g.

Hydrogen sulfide, H2S, is produced during decomposition of organic matter. When 0.3620 mol H2S burns to produce SO2 (g) and H2O(g), -187.5 kJ of heat is released. What is this heat in kilocalories? Heat = kcal

Classify the substances below as reactants or products and state their state of 2NaHCO3 (s) → Na,CO3 (s) + H20 (1) + CO2 (g) matter:

In the following reaction, how many grams of CH3OH are required to produce 1.578 x 10° kJ of heat? 2 CH3OH (1) +3 O2 (g) → 2 CO2 (g) + 4 H2O(g) AH = -1280. kJ/mol Please do not include units in your answer.

It took 16641664 J to raise the temperature of a sample of water from 12.512.5 °C to 34.534.5 °C. Convert 16641664 J to calories.

Consider these reactions: Reaction 1: H2(g) + Cl2(g) 2HCl(9) AH = -184.6 kJ Reaction 2: 20F2(g) → O2(g) +2F2(g) AH=-49.4 kJ Reaction 3: Na (g) +202 (9) 2NO2(g) AH = +66.4 kJ Use Reaction 1. Determine the mass, in grams, of chlorine gas consumed (with excess H₂) when 1,409.0 kJ of energy is released from the system. Round to the nearest whole number .
