I would believe that the answer to this question would be the "Touching toads gives you warts
I would radiation a robotics arm but for a heated surphace is Shiny surfaces are poor absorbers and emitters (but they are good reflectors of infrared radiation).
The given compound is
Each formula unit of has 2 mol Potassium (K) atoms, 2 mol Chromium (Cr) atoms and 7 mol Oxygen (O) atoms.
Atomic weight of potassium is 39.0983 amu
Atomic weight of Chromium is 51.9961 amu
Atomic weight of Oxygen is 15.9994 amu.
Therefore the formula weight of
= 294.1846 amu
Salad would be a mixture because it is not chemically combined, if needed you could physically take it apart. So your answer would be A.)
Answer:
In FeO iron atom exist as Fe+ cation but in Fe2O3 iron atom exist as Fe3+ cation.
Explanation:
Feo=Fe+ + O-
Fe2O3 =2Fe3+ + 3O2-
The difference in the charge of iron cation deeply affect the compound formulas because in FeO the Fe cation has 1 unit positive charge where in Fe2O3 the Fe cation has 3 units positive charge.
That"s why these two chemical compounds made up of similar atoms differ in their chemical formulas.
