Experiment In this lab we were asked to observe changes and colors when mixing two or three chemicals together. The actual experiment itself used twelve different pipits and three chemicals I selected from my house. To begin‚ I first gathered everything‚ including the 96 well plate‚ 24 well plate‚ goggles‚ and gloves along with the observations of chemical changes bag. I set it up all on the the kitchen table that had paper towels on it. Next‚ I made my data table so that I could record my reactions

bonds formed between two ions by the transfer of electrons. The speed at which a chemical reaction proceeds is known as the rate of reaction. The rate of almost every reaction can be increased or decreased due to different factor. Scientists have identified five factors that affect the rate of reaction. The five factors are temperature‚ concentration of the reactants‚ surface area‚ agitation (mixing)‚ and catalyst (chemical helpers). The collision theory states that the rate of a reaction is directly

Naming Chemical Formulas Chemical Nomenclature There are over 19 million known chemical substances. Without some type of system‚ naming these substances would be hopelessly complicated. The system used in naming substances is called chemical nomenclature. There are two major divisions to the International Union of Pure and Applied Chemistry (IUPAC) system: inorganic nomenclature organic nomenclature Organic compounds contain carbon‚ usually in combination with hydrogen‚ oxygen‚ nitrogen

This could be seen more easily with the black paper underneath the well plate B. HCl + BTB C1 Once I added the Bromothymol Blue indicator‚ it turned an orange-like color C. NH3 + BTB E1 The reaction turned dark blue. When Bromothymol Blue reacts with an acid‚ it turned orange‚ and when it reacts with a base‚ the end result is blue. D. HCl

Chemical Reaction:- The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance. (b) Change of colour of substance

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚
