Students will further develop their problem-solving and investigation skills as they investigate chemical processes, and will refine their ability to communicate scientific information. The reflection of any alpha particles at all was surprising proof that the atom did contain something inside it. Temperature and K sp Nitrate salts are typically highly soluble and can be assumed to dissociate completely. Their hypothesis will be what carboxylic acid and alcohol are needed to create this ester. Students will be engaged when they are able to see the connection between the scientific concepts they are learning and their application in the world around them and in real-life situations. There are 100s of different indicators to choose from with many different pH end points between 0 - 14. The topics as you see mostly involves physical chemistry so strong problem solving skills is an asset.
This lab write-up is optional. Students began a powerpoint note on equilibrium. Students rotated four times, and the summarized what had been written on each vertical space. The students worked through examples of how to write the equilibrium constant expression, and how to find its value, given concentrations at equilibrium. Phase 3: externally oriented planning- frustrated with highly political yet. The molecule that is still solid at room temperature would have the lower entropy.
As part of assessment, teachers provide students with descriptive feedback that guides their efforts towards improvement. . An aldehyde was used to show how a carboxylic acid is created. It takes 142,875 J of heat to bring the sample to a boil at 100˚C. There are 5 essay questions worth 20 points each.
Homework: page 486 1-4, page 489 5, page 493 10. A grade 11 review test will be held Friday Feb 9. The Marshmallow Review Sheet contains both the question and the answer to each of the organic compounds. P4: Students used molecular sets to complete the handout on alcohols. Continue to work on the nomenclature sheets previously handed out.
Oxygen forms an O 2- anion because it is in group 6A 16 and can easily gain two more electrons to get a full octet. Examples of determining cell reactions in an electrolytic cell were completed. Students began a powerpoint note on equilibrium. Homework: write up the analysis of the lab in your lab book. All 6 Cl-C-Cl bond angles are 109. Dates were chosen for upcoming assessments. May 7 All students completed an Inquiry question about finding rate of reaction from experimental data as a review for the test on Thursday.
Enabling students to learn English language skills will contribute to their success in the larger world. An aldehyde was used to show how a carboxylic acid is created. Two isomers have the same bonding, but different arrangements in across carbon-carbon double bonds. Think of the periodic trends that affect this: electronegativity, ionization energy, electron affinity, atomic radius, and nuclear charge. Amphoteric compounds are not located on the far left or far right ends of the equations shown above.
Literacy, Mathematical Literacy, and Inquiry Skills Literacy is defined as the ability to use language and images in rich and varied forms to read, write, listen, view, represent, and think critically about ideas. When iron rusts, it is because the iron is acting as the anode and Hydrogen and or Oxygen is acting as the cathode. Homework: Identify the main shape of the molecules on the worksheet. Students were shown Maxwell Boltzman curves, and used them to determine if increasing temperature will dramatically affect the rate of reaction. For main group, last numeral of group number is same as number of valence e- Ex: strontium in group 15 and 5 valence electrons Exception is helium 2 valence electrons and in group 18 but energy level is complete 2. The alpha particles need a mass like a nucleus to reflect, and would not be reflected from these tiny, lone subatomic particles in Thomson's model. Aufbau Principle: Electrons are placed in the lowest energy subshell available.
When naming a molecule with many different side groups, the side groups are listed alphabetically according to the root name of the side group and the prefixes. You might think this because of the densely packed atomic structure of metals, but the malleability of metals allows the metal to be compact, without being a single crystal. Of the elements given, the most electronegative alkali earth metal is most easily oxidized - this is Rubidium, Rb. Where you are having difficulty, look in Appendix D for review of that topic and more questions. Students started a note on organic chemistry.
Students worked on review for tomorrow's lab test , and determining rates of reaction. June 11 P2- Teacher absent for most of class. The single vertical line represents a difference between phases solid and aqueous while the double bar indicates separate cells anode and cathode connected with a salt bridge or porous membrane. Homework- study for the exam. Students were introduced to vob for nitrogen compounds, and then practiced more problems before working on the homework handouts.
