Higher Chemistry Mole Calculations Moles and Number 1 mole of any substance contains the same number of atoms/molecules/ions as there are atoms in a 12g sample of carbon -12 12g of carbon-12 contains a constant number of atoms. This number is known as the Avogadro constant (L) and is equal to 6.02 x 1023. 1 mole of carbon-12 contains 6.02 x 1023 atoms. Therefore‚ 1 mole of any substance contains 6.02 x 1023 atoms/molecules/ions. For example‚ 1 mole of aluminium contains

ORGANIC AND INORGANIC CONSTITUENT IN ESSENTIAL IN PLANTS AND NUTRIENTS REQUIRED TO PLANTS Organic constituent DEFINITION An organ‚ system‚ or other discrete element of an organism the part of the plant that carries out photosynthesis. EXPLANATION: The chemical compounds of living things are known as organic compounds because of their association with organisms. Organic compounds‚ which are the compounds associated with life processes‚ are the subject matter of organic chemistry. Among the numerous

Experiment I: Thermochemistry Background: Thermochemistry is the branch of chemistry that focuses on the studies of chemical reactions or physical changes and heat associated with chemical reactions. According to the first law of thermodynamics‚ energy cannot be created or destroyed but it can be converted from one form into another and/or transferred between different atoms‚ molecules‚ or substances. In general‚ energy can be classified into two categories: kinetic and potential. Kinetic energy

The enhanced productivity in agriculture sector can be achieved by improved and efficient crop husbandry. Applying fertilizers in required quantity and quality at appropriate times with the using of other inputs can improve yield per healthcare of agriculture crops. In the article‚ the production of fertilizers‚ factors that affect on it and other relevant aspects have been analyzed. Introduction The fertilizer industry has played a significant and responsible role in the development of both

following: * Lithium sulfate Lithium sulfate would give off a pink flame when lit‚ making it easy to identify and relable against the other substances. * Potassium nitrate Also‚ potassium would give off a light purple color when lit‚ making it simple to identify against the other substances. * Ammonium chloride Ammonium‚ although not tested in this lab‚ would be easy to pick out since it most likely does not give off a pink or purple flame as lithium sulfate and potassium sulfate do‚ respectively

Introduction: Being able to identify a particular bacterial species is important. It is very useful in knowing its risk of toxicity to humans or animals‚ its resistance or susceptibility to antibiotics‚ and determining how to control its growth or kill it altogether. The purpose of these procedures is to discovery the identity of an unknown microbe by observing its reactions to a barrage of chemical and physical tests. Different microorganisms react in different ways‚ due to their function‚ digestibility

Chemistry Review (mid-term) 1. Use the equation for atomic mass to answer the following questions. (http://johnheilchem10.escuelacampoalegre.wikispaces.net/file/view/average+atomic+mass+calculations+-+3.pdf) 1. Argon has three naturally occurring isotopes: argon-36‚ argon-38‚ and argon-40. Based on argon’sreported atomic mass‚ which isotope do you think is the most abundant in nature? Explain. 2. Copper is made of two isotopes. Copper-63 is 69.17% abundant and it has a mass of 62.9296 amu.
