Imagine that a new metal, given the symbol X, has been discovered. It lies between calcium and magnesium in the reactivity series. Describe the reaction of excess X with dilute sulfuric acid and give word and balanced symbol equations. (metal X forms +2 ions).

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
