If a student analyzes data and finds that they got 0.480 moles of an unknown metal and 0.240 moles of oxygen, what is the mole ratio of metal to oxygen?

The ratio of the metal to oxygen is 2:1

Explanation:

Given parameters:

Number of moles of unknown metals = 0.48moles

Number of moles of oxygen = 0.24moles

To find the mole ratio:

We divide the given moles by the smallest values. This gives the simplest form of the two elements:

    Elements                          Unkown metal                Oxygen

Number of moles                      0.48                              0.24

simplest form                          0.48/0.24                   0.24/0.24

                                                       2                                    1

The ratio of the metal to oxygen is 2:1

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
