A 50g sample of a mystery metal requires 408 J of heat to raise its temperature from 12ºC to 20ºC. What is the identity of the mystery metal? A. sodium B. magnesium C. zinc D. aluminum

If the same amount of cacl2 is added to equal volumes of water and maple syrup, which will have the higher temperature?

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.

Determine the percent sulfuric acid by mass of a 1.61 m aqueous solution of h2so4. %
