The first law of thermodynamics states that Group of answer choices a. energy is transferred from the surroundings to the system during a combustion reaction. b. if a system loses energy to the surroundings, then the surroundings must do an equal amount of work on the system. if the surroundings gain energy from the system, then the system must lose an equal amount of energy. c. energy is transferred from the system to the surroundings during a combustion reaction. d. if a system does work on the surroundings, then the surroundings must transfer an equal amount of energy to the system.

Option B is the most correct.

If a system loses energy to the surroundings, then the surroundings must do an equal amount of work on the system. if the surroundings gain energy from the system, then the system must lose an equal amount of energy.

Explanation:

The first law of thermodynamics is the law of conservation of energy. It explains that energy can neither be created nor destroyed, but can only be transformed from one form to another of transferred from one place to another (In various forms at times).

So, if a system gains energy from the surroundings, it is evident that this energy wasn't created, it was transferred in from the surroundings, meaning that the surroundings have lost that same amount of energy and vice versa.

So, it is obvious why option B is the most correct of all the options.

Hope this Helps!!!

you didnt put any of the following

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
