Let's say you blew three baloons to the same size and left one baloon at room temperature, and kept one baloon in an ice bath, and one baloon above a hot water container. You left the laboratory for 30 minutes and when you came back, you saw that the size of the baloon in the ice bath was smaller than before and size of the baloon above hot water container was larger than the original size. As chemistry student, how do you explain the reason for this observation.

Constants I Periodic Table Part A For the following reaction studied in the gas phase (Fridgen, T. D., et al. J. Phys. Chem. A 2005, 109, 7519): Ci-+ C3H7CN → C1C3H7+ CN- Is the overall reaction exothermic or endothermic? Match the words in the left column to the appropriate blanks in the sentence on the right. the following potential energy surface was derived: [Cl–C;H;-CN]¯ Reset Help ClC;H,+ CN exothermic The overall reaction is because at a higher energy endothermic than the products are the reactants are Cl +C;H¬CN the transition state is [CIC;H,-CN] Submit Request Answer [Cl–C;H;CN] Reaction progress Part B The mechanism for the reaction, based on the potential energy diagram, There are six activation energies, one associated with each of the rate constants in the mechanism. Two of the elementary steps are barrierless, in that they have activation can be written as: energies equalling zero. Which of the six activation energies, Eal, Ea–1 Ea2 Ea-2 Ea3 Ea-3 are equal to zero? k…

SpaceX recently launched their Falcon Heavy rocket (Feb. 6, 2018). It is based on their existing Falcon 9 rocket. The Falcon 9 rocket has a first stage which is a 40 m high by 3.7 m diameter cylinder. This cylinder contains the fuel used to propel the rocket which consists of RP-1 (rocket propellant-1, high grade kerosene), and liquid oxygen, O2 (`). RP-1 is a complex mixture of hydrocarbons but let’s approximate it with a chemical composition of C12H26. The densities of the fuel are ρ (RP − 1) = 0.83 g cm3 ρ (liquid O2) = 1.141 g cm3 If the total volume available for the two tanks is contained in the 40 m high by 3.7 m diameter first stage, determine the volume of each individual tank that will provide the exact amount of RP-1 and oxygen for the reation (no limiting reagent) and take up the entire volume of the first stage. Here are some suggestions to guide you. 1. Write a balanced combustion reaction for C12H26 with O2. 2. Determine the ratio of the volumes of the individual RP-1…
