Answer Question number 6 4Gılll Gilll00:21* 67%f [Template] Mo... /Answer the following problems:1. Two solid objects, A and B, are placed in boiling water and allowed to come tothe temperature of the water. Each is then lifted out and placed in separatebeakers containing 1000 g of water at 10.0 °C. Object A increases the watertemperature by 3.50 °C; B increases the water temperature by 2.60 C.a. Which object has the larger heat capacity?b. What can you say about the specific heats of A and B?2. The specific heat of octane, CsHss0), is 2.22 Jig-K.a. How many J of heat are needed to raise the temperature of 80.0 g ofoctane from 10.0 to 25.0 °C?b. Which will require more heat, increasing the temperature of 1 mol ofCH18, by a certain amount or increasing the temperature of 1 mol ofHOm by the same amount?3. Calculate the enthalpy change for the reactionP.0a (4) + 2 02 (0) - P,010(5)given the following enthalpies of reaction:AH = -1640.1 k)Pa (s) + 302 (9) - P,0.4)Pa (s) + 5 02 (9) - P,010 (9)AH = -2940.1 k)4.

Gasoline is composed primarily of hydrocarbons, including many with eightcarbon atoms, called octanes. One of the deanest-buming octanes is acompound called 2,3,4- trimethylpentane, which has the following structuralformula:сн, сн, сн,H;C-CH-CH-CH-CH,The complete combustion of one mole of this compound to COzig and H2Ogleads to AH° = -5064.9 k).a. Write a balanced equation for the combustion of 1 mol of CaH18n.b. By using the information in this problem and data in the thermodynamicproperties table, calculate AH for 2,3,4-trimethylpentane.6. The following is known as the thermite reaction:2 Alg + Fe,0s(4) - Al,03(9) + 2 Feg)This highly exothermic reaction is used for welding massive units, such as propellers forlarge ships. Using standard enthalpies of formation, calculate AH° for this reaction.I hope you'll enjoy the taskAnswer Key

The standard enthalpy of formation for the reactants and products are – Al (s) = 0 kJ/mol Fe2O3 (s)…
