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

Premature Rupture of Membranes Article Review As the article states‚ premature rupture of membranes occurs when the amniotic membranes surrounding the growing fetus rupture causing a loss of fluid before 37 weeks of gestation and before the onset of natural labor. PPROM‚ preterm premature rupture of membranes is seen often in women who smoke and use recreational drugs. If PPROM occurs before 26 weeks of gestation it is considered extreme and more often than not leads to more serious complications

eight types of chemical reactions. These eight reactions are Decomposition‚ Composition‚ Acid/Base‚ Synthesis‚ Single-Replacement‚ Double-Replacement‚ Precipitation‚ and Redox. Though these eight could be referred to as the same due to them being chemical reactions. They are actually very different. An example of this difference is Decomposition and Synthesis. Decomposition is when a compound is broken into smaller chemical species while a Synthesis reaction is two or more chemical species combining

electrically excitable membrane changes its electric potential. In other words‚ how is the cell membrane excited? At the surface of the cell membrane‚ there are three classes of gated channels exist‚ chemically gated or ligand-gated channels‚ voltage-gated channels‚ and mechanically gated channels. Originally‚ at the resting membrane potential‚ most of the gated channels are closed. However‚ when these gated channels open‚ the movement of ions across the membrane will changes the membrane potential. In the
