ELECTROLYSIS Electrolysis decomposition of compound using electricity Electrolyte an ionic compound which conducts electric current in molten or aqueous solution‚ being decomposed in the process. Electrode a rod or plate where electricity enters or leaves electrolyte during electrolysis. Reactions occur at electrodes. Discharge the removal of electrons from negative ions to form atoms or the gain of electrons of positive ions to become atoms. Anode

Life is a Stage and all of us are Merely Players‚ Acting out our Parts Symbolic interactionism is one of the leading sociological theories having a long intellectual history dating back to the American philosopher George Herbert Mead. Symbolic interactionism centers on the study of connections between the individual (micro-level) and larger social structures. The goal of symbolic interactionism is to illustrate how shared meaning is created. The theory explains that we all have our own sense of what

Electrolysis Electrolysis is the process by which ionic substances are broken down into simpler substances using electricity. During electrolysis‚ metals and gases may form at the electrodes. What is electrolysis? Ionic substances contain charged particles called ions. For example‚ lead bromide contains positively charged lead ions and negatively charged bromide ions. Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric

Topic 11a – Group 7‚ the Halogens Revision Notes 1) Trends in physical properties of the elements • At room temperature‚ Cl2 is a pale green gas‚ Br2 is a brown liquid‚ I2 is a blue-black solid. • In Group 7‚ boiling point increases down the group because the molecules have more electrons and‚ therefore‚ stronger van der Waal’s forces which require more energy to overcome them • Electronegativity is the ability of an atom to attract the electrons in a covalent bond • Down

about a population. Population parameters are what is measured‚ for example price‚ and sampling statistics describe who is measured. Frequency distributions are frequency percentages (what is) and probability (what may be)‚ which is the long-run relative frequency with which an event will occur. It is one of the most common ways to summarize a set of data. A significance level is a critical probability associated with a statistical hypothesis test that indicates how likely it is that an inference

This dynamic is that experiences are often shared with others; where as material possessions are more inclined to individual use. “If so‚ variations in the sociality of experiences should moderate the extent to which they provide happiness relative to material possessions. Extensive research shows that social relations are influential sources of happiness” (Caprariello & Reis‚ 2013). Therefore material possessions intended for social use may lead to greater happiness than possessions intended

when there is less starch present the intensity of the color purple decreases. The the objective of this experiment was whether the change in temperature and the speed of reactivity of amylase is directly proportional or not. The hypothesis was with the increase in temperature there would be an increase in the speed of reactivity of amylase with starch. Results showed that with the increase in temperature there is an increase in the speed but after 37ºC the rate of reaction decreased. This proved
