How come you cant use the Mass Ratio to determine the empirical formula, whereas the Mole Ratio enables you to do so when dealing with Mg and O Plz help im studying for a test and have stumbled across this question... Thx

A student decides NOT to heat the crucible before adding Mg sample. Would you expect the to cause the molar ration or Mg and O to be higher or lower than the actual value? ---There is no specific reaction given, no other detail, nothing, I don...

a. write the balanced reaction that occurs when water is added to magnesium nitride. b. If the Mg3N2 is not decomposed, will the report magnesium oxygen ration be high or low?Explain HINT: the Mg:N mass ratio is 1:0.38 and the Mg:O mass ...

Ok, this is my bug out bag. I need help coming up with things that I missed that I need to include in it. Dont say that this could not all fit in a bag because it easily could. My BoB so far: Survival Kit Food / Water: -3600 ...
