Monday, December 13, 2010. YEAR 10 CAMP ON THE WAIOEKA, DECEMBER 2010. The camp ran between December 6th and December 9th 2010 and involved one overnight camp / bivvy along the banks of the Waioeka River between Koranga Forks Hut and Wairata and two nights camping on Redpath's Farm at Wairata. But we got down through Nutcracker and Corkscrew along with the rest of the river, albeit it with the occasional boat walk! Below is a slide show of some of the photos I took on the camp:.

Sunday, April 1, 2012. New Standard: A.S. 91161 Carry out quantitative analysis. This standard is an internally assessed standard and will involve carrying out an acid-base titration along with chemical calculations involving Moles, Concentration, Volume: n = c x V (V = n ÷ c, c = n ÷ V ). In order to carry out this internal accurately with the aim of achieving at least a merit you will need to be able to carry out an accurate titration-so here goes. 183; WHAT IS THE CONCENTRATION OF THE ACID?

Friday, November 19, 2010. This is the start, middle and end of trying to understand chemistry and how and why elements react:. Remember group numbers and valence shell electrons! There are a lot of elements here and first impressions maybe that trying to remmber the elements in order up to the first 20 is too difficult.wrong! This is where mnemonics come in! Opata, - He. Rothy, - N. Lly -(the) - Na. Erson, - S. Here is another one for more elements. Subscribe to: Post Comments (Atom).

Mainly Science@Gisboyshigh: YEAR 11PY CHEMISTRY REVISION
http://mainlyscience-gisboyshigh.blogspot.com/2010/10/year-11py-chemistry-revision.html
Friday, October 22, 2010. YEAR 11PY CHEMISTRY REVISION. The basic starting point is understanding electron configuration of the elements and realising that we are only concerned with the outer shell of electrons as these electrons are the ones involved in bonding. REMEMBER this is the valence shell and all elements in the same group have the same valency and the same Lewis Dot Diagram configuration! 2 Electrons need to be drawn on the four sides of the Symbol on their own first. Help with redox reactions.

Wednesday, September 22, 2010. NCEA REPORT ON EXTERNAL ASSESSMENTS.11 PY. This is a shortened version of the NCEA Report on Exam results for the Standards assessed for 11 PY.some of the general points are of relevance to 10SiA1 as well-so read on Boys! Students who gained Achievement with Excellence wrote detailed answers demonstrating a good understanding of the concepts. In addition they had clearly carried out practical work and understood and remembered it as this was reflected in their answers.

Monday, July 26, 2010. FACTORS AFFECTING THE RATE OF CHEMICAL REACTION. From previous classes we know that: Reactants- - - - - - - - - Products. Or a number of reactants combine to form a product / products. We can also say that the particles in the products collide in order for a reactant to be formed. Depending on the types of reactant the time taken for a reaction to occur can vary considerably. Rate of Reaction = amount of reactant(s) used or product(s) formed / Time Taken. What this graph tells us t...
