5g of hydrogen gas at initial pressure 3 atm and an initial temperature 27℃ are compressed adiabatically to one half the initial volume. If the specific heat capacities for hydrogen gas are = 1.03 × 104/. and = 1.44 × 104/. . Determine i. The final pressure (4) ii. The final temperature (2) iii. The work done by the gas (2

Sodium chloride, nacl, is formed when a sodium atom transfers its electron to a chlorine atom. the difference in charge between the two atoms creates a(n) attraction that bonds them together.

1kg of water needs to recieve 4200j of energy to go from 90 degrees to 91 degrees. what is the specific heat capacity of water? what are the units?

Which type of reaction is shown in this energy diagram? energy products activation energy reactants time o a. endothermic, because energy is released to the surroundings o b. exothermic, because energy is absorbed from the surroundings o c. exothermic, because energy is released to the surroundings o d. endothermic, because energy is absorbed from the surroundings
