Video transcript

everyone's are given the following possible fuel substitutes with methanol, ethanol and I so obtained. And so part A. Whereas which fuel produces the most energy per unit mass and for part B. Whereas which fuel produces the most energy per unit volume for part eight. We need to convert the entropy of combustion for each from Killjoys Primal. The killed jules program using the smaller masses from methanol 726 1. Hello jules. Caramel in one more that the water mass. And this is 12.011 g plus four House 1.008g plus .999 g. Just give us 32.04 g. You're gonna get 22 0.66. Hello jules program at the knot Have 1,366.8. Hello jules. And in one mall have the molar mass. And this is to 12.011 g. A six House 1.008g. That's 15 .999 g. We're gonna get 46 07 g. Forget 29.67 little jewels program for a seedling. 1,301 one killer jaws remote. And in one mall have the molar mass which is to Times 12.011g. Last two It was 1.008 g. We're going to get 26 04 g. Bring it 49 0.97. Hello jones program for isil octane, 5461. Hello jules. Um also And in one mold the molar mass which is eight Times 12.011g plus 18 Times 1.008g. Just give us 114 23 grounds. Can we get 47 0.81. Hello jules program here. We see that as settling. It's going to produce the most energy per unit mass. And for part B we need to convert each from killer jewels. Program to kill jaws. Our male leader using the densities from methanol of 22.66 gold jewels. Program. The density is 0.792 grams per male leader. We're gonna get 17. killer jules. Later at the mall 29.67 Hell jaws or one g. The density is 0.789 grams For one minute later. Gonna get 23 at 41 little jewels. Permanent leader for a seat. Elaine 49.97. Bill Jules for one g. And the density is 0.00 g For one minute later. We're gonna get 0.059. Hello jules. Preamble leader. Isil octane 47.81. Hello jules for one g. And the density is 0.69 grams per one male leader. We're gonna get 32 0.99. Billy Joel's primary leader here we see that Isil octane. Going to produce the most energy per unit volume. Thanks for watching my video. And I hope it was helpful.

A coffee-cup calorimeter of the type shown in Figure 5.18 contains 150.0 g of water at 25.1°C A 121.0-g block of copper metal is heated to 100.4°C by putting it in a beaker of boiling water. The specific heat of Cu(s) is 0.385 J/g-K The Cu is added to the calorimeter, and after a time the contents of the cup reach a constant temperature of 30.1°C (d) What would be the final temperature of the system if all the heat lost by the copper block were absorbed by the water in the calorimeter?

We can use Hess's law to calculate enthalpy changes that cannot be measured. One such reaction is the conversion of methane to ethane: 2 CH4(g) → C2H6(g) + H2(g) Calculate the ΔH° for this reaction using the following thermochemical data: CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(l) ΔH° = -890.3 kJ 2 H2(g) + O2(g) → 2 H2O(l) H° = -571.6 kJ 2 C2H6(g) + 7 O2(g) → 4 CO2(g) + 6 H2O(l) ΔH° = -3120.8 kJ

When magnesium metal is burned in air (Figure 3.6), two products are produced. One is magnesium oxide, MgO. The other is the product of the reaction of Mg with molecular nitrogen, magnesium nitride. When water is added to magnesium nitride, it reacts to form magnesium oxide and ammonia gas. (e) The standard enthalpy of formation of solid magnesium nitride is -461.08 kJ>mol. Calculate the standard enthalpy change for the reaction between magnesium metal and ammonia gas.

Textbook Question

Sucrose (C12H22O11) is produced by plants as follows: 12 CO2(g) + 11 H2O(l) → C12H22O11 + 12 O2(g) H = 5645 kJ About 4.8 g of sucrose is produced per day per square meter of the earth's surface. The energy for this endothermic reaction is supplied by the sunlight. About 0.1 % of the sunlight that reaches the earth is used to produce sucrose. Calculate the total energy the sun supplies for each square meter of surface area. Give your answer in kilowatts per square meter 1kW/m2 where 1W = 1 J/s2.
