Hydrogen and oxygen react under a specificset of conditions to produce water accordingto the equation2 H2(g) + O2(g) −→ 2 H2O(g).How much hydrogen would be required toproduce 3.9 mol of water?Answer in units of mol.

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

that tool would be a compass

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .
