Decomposition reaction - ANSWERStarts with one reactant and ends with two or more products. Synthesis/formation/combination reaction - ANSWERStarts with two reactants and ends up with one product. Single displacement - ANSWERUncombined element takes place of the combined element in the compound. Double displacement - ANSWERBoth reactants are compounds and both products are compounds. Combustion reaction - ANSWERWhen reactants are oxygen and a hydro-carbon and the products are water a...

Mass spectrometry using lasers to ionise atoms into cations, then measure the abundance and mass using their mass-tocharge ratios Mass to charge ratio the mass of an ion divided by its charge (usually +1 in mass spectrometry) units: m/z relative atomic mass the average mass of an atom of an element relative to 1/12 of an atom of the isotope C-12 relative isotopic mass the relative mass an atom of an isotope relative to 1/12 of the mass of a C-12 atom relative molecular mass the relati...

General Inorganic Chemistry Exam With 100% Correct Answers 2024 Dalton's Atomic theory - answerElements are composed of tiny indivisible particles called atoms. Inorganic Chemistry - answerstudy of the synthesis and behavior in inorganic and organometallic compounds Law of Multiple Proportions - answerIf two elements combine to form more than one compound, the ratio of the mass of an element to a fixed mass of the other element is a whole number or a simple fraction. Law of Conservatio...

Rutherford's Gold Foil Experiment - proposed that atoms consist of a tiny, massive, positive nucleus surrounded by electrons nucleus - contains all the positive charge and nearly all the mass of the atom James Chadwick - discovered the neutron cathode rays - move from negative electrode to positive electrode (like electrons in a voltaic cell) Thompson's Cathode Ray Experiment - discovery of the electron (also the discovery that atoms are divisible into smaller particles) Milliki...

ACS Chemistry 101 & 102 Final Exam Review 44 Questions with Verified Answers What is the difference between a homogeneous and heterogeneous mixture? Can they be separated? - CORRECT ANSWER A homogeneous mixture is a uniform composition throughout whereas a heterogeneous mixture has other substances. They can be separated but through physical processes. What is the difference between a physical and chemical property? Physical vs chemical change? - CORRECT ANSWER A physical prope...
