Sample A is found to contain 34.9 g of nitrogen and 39.9 g of oxygen. Sample B is found to contain 87.9 g of nitrogen and 201 g of oxygen. Do samples A and B obey the law of definite proportions, the law of multiple proportions, both laws, or neither law? Could A and B be samples of the same compound or are they different compounds?

Introduction to Soll Scdence- Lab 3 Chemial Elements Name Date Some lasics regarding Chemical Elements A Chemical element found on the Perlodic Table of Elements (found on the Inside cover of your text) isa pure substance which cannot be decomposed by chemical change. The names of Elements are often abbrevlated to slmplify formoulas ustng these elements. These abbreviations are refened to u chemical symbols. For Hydrogen, the symbol "H', for Onygen, "O, and for Carbon, "C. Sometimes two letters are necessary to distingutsh bebween two or more elements when the names of the elements begin with the sume letter. For Example Ca for Caldum. Cr for Chromlum, Co for Cobalt, Cl for Chlorine, etc. No symbols contain more than two letters and the first letter is always capitalized. Some symbolk are abbrevlations of Latin names ofelements (Le. Fe for Iron; Latin, ferrum). Each Element has an atomic number and an atomic welght. The welght is in relative ternos as an atom of exch element is…
