These elements are frequently found as oxides, and need to be separated in order to extract the pure element. Before going through this effort, it is useful to know what amount of the element can be extracted. How many moles of element A can be extracted from 175 grams of A5012? N 369.52
Imass f# 7. A fictitious element which we will call dearbornium (Db) is made up of two isotopes. A sample of Db contains 2233 atoms of 292Db and 4026 atoms of 29SD6. a) Calculate the percent abundance of each isotope in this sample. Show work and write your answers in the spaces provided. Give the answers to 5 sig.figs. 295 Db = 292 Db = b) If the mass of 292DB is 291.95 amu and that of 295Db is 294.97 amu, what is the average atomic mass of dearbornium? Write the equation and clearly show your work.

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…
