NaOH was added drop by drop until yellow color develops that gradually deepens into a brown color. 2.) Saturation with MgSO4 1 ml of milk was placed in a test tube. Solid MgSO4 was added until precipitate formed. 3.) Test for formaldehyde preservative in milk 1 ml of milk was placed in a test tube. 1 ml of the solution containing FeCl3 in HCl

The 8 Phases of the Moon Phase 1 - New Moon - The side of the moon that is facing the Earth is not lit up by the sun. At this time the moon is not visible. Phase 2 - Waxing Crescent - A small part (less than 1/2) of the moon is lit up at this point. The part that is lit up is slowly getting bigger. Phase 3 - First Quarter - One half of the moon is lit up by the sun at this point. The part that is lit up is slowly getting bigger. Phase 4 - Waxing Gibbous - At this time half

3 Three-Phase A.C. Circuits Learning Outcomes This chapter introduces the concepts and principles of the three-phase electrical supply‚ and the corresponding circuits. On completion you should be able to: 1 Describe the reasons for‚ and the generation of the three-phase supply. 2 Distinguish between star (3 and 4-wire) and delta connections. 3 State the relative advantages of three-phase systems compared with single-phase-systems. 4 Solve three-phase circuits in terms of phase and line quantities

Action Phases The Rubicon is a mindset theory of action phases in decision-making proposing that care should be taken first in making the decision‚ then commitment sustained once the decision is made. The model suggests that there is an activation of different cognitive procedures in the process of task tackling by persons. Particularly‚ the mindset theory of action phases forms the foundation of research in the planning process (Brandstätter‚ Heimbeck‚ Malzacher‚ & Frese‚ 37-59)‚ which envelopes

A. Introduction Three phase transformers are used throughout industry to change values of three-phase voltage and current. Since three-phase power is the most common way in which power is produced‚ transmitted‚ and used‚ an understanding of how three phase transformer connections are made is essential. In this section it will discuss different types of three phase transformers connections. A three-phase transformer is constructed by winding three single-phase transformers on a single core. These

1 and Mitosis are very similar events‚ however‚ they have certain differences. One difference is crossing over. Meiosis 1 does cross over and because of that‚ it creates genetic changes. Mitosis ‚ on the other hand‚ does not cross over. Something else that is different is the way it occurs. Meiosis 1 is sexual but Mitosis is asexual. Another change is the number of divisions that each event goes through. Meiosis 1 goes through 2 divisions which ends up having 4 haploid cells‚ however Mitosis only

The Pleiades star cluster or “the Seven Sisters” is among the nearest star clusters to Earth and the most discernible to the naked eye. Visible from nearly every location on the planet‚ Pleiades can be seen from the north pole to the southernmost tip of South America. Historically‚ the Pleiades were seen as a group of seven stars‚ Alcyone‚ Atlas‚ Electra‚ Maia‚ Merope‚ Taygeta and Pleione. With modern technology‚ we now know that the Pleiades cluster is actually comprised of several hundred stars

chapter dedicated to Phase I and Phase II of the tender evaluation process. Essentially in each phase you are doing risk identification and risk quantification. The assignment is to compare the two phases discussed and then answer questions that compare the two phases. Since each phase is designed to serve a different purpose‚ you can’t really say one phase is better than another. Both phases are important in order to understand the risks during the tender evaluation process. Phase I that is described

Paragraph 1 Quartz-type iron phosphate‚ FePO4‚ exists in different phases at different temperatures. At low temperatures‚ it exists in the α-quartz-type phase‚ while at high temperatures‚ it exists in the β-quartz-type phase. The α-β phase transition occurs at 980K. In terms of lattice symmetry‚ α-FePO4 exhibits a trigonal lattice system‚ whereas β-FePO4 exhibits a hexagonal lattice system. In terms of space symmetry‚ α-FePO4 belongs to the P3121 space group‚ while β-FePO4 belongs to the P6422 space
