Figure 2 shows the chemicals given to a student.
The student wants to investigate the reactivity of the four metals.
Outline a plan the student could use to investigate the relative reactivity of the four metals, W, X, Y and Z.
The plan should use the fact that all four metals react exothermically with dilute sulfuric acid.
You should name the apparatus used and comment on the safe use of the chemicals

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.
