The lowest value of the henry's law for methane gas (ch4) will be obtained with as the solvent and a temperature of k.

The lowest value of the henry's law for methane gas (CH₄) will be obtained with H₂O as the solvent and a temperature of  349 K.

The lowest value of the henry's law for methane gas (CH₄) will be obtained with H₂O as the solvent and a temperature of 349 K.  

Henry's law: This law states that at a constant temperature, the amount of a gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas that in equilibrium with that liquid.

Mathematically it can be written as:

So, for the methane gas , lowest value of the henry's law obtained at  349 K and with H₂O as the solvent.

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
