Associate Level Material Appendix D Research Plan As part of your research plan‚ you must first draft a research question for your research paper that will guide the rest of your writing. A research question‚ which is more specific and focused than a general topic‚ is the question that your research paper will be answering. For example‚ if your general area of interest is social security‚ a possible research question might ask‚ “How can low-income families save more money if the United

areas with poor road conditions and dilapidated bridges‚ was not feasible. This prompted him to request from PSC a change to a shorter route Marbel to Dadiangas. Said request for amendment of route was approved in 1964 using 6 units’ regular buses and 1 reserve bus. In April 1971‚ YBL opened the Tacurong to General Santos route via Tantangan and Isulan. Every year thereafter‚ more units were fielded in its authorized lines. As of December 1975‚ YBL had 32 units in operation. Inspite of the presence

Lime scale form when hot water is heated about 61’C. All the acids listed about remove lime scale because the ions in the acids react with the calcium ions in limescale to then form a soluble salt. The acids also react with the carbonates in lime scale to produce water and carbon dioxide. Then the whole solution washes out taking away as much lime scale and possible. Sulfamic acid The advantages of using sulfamic acid as a de-scaler are that it is the faster de-scaler which means it can give

The three mineral acids commonly found in the laboratory are hydrochloric acid‚ sulphuric acid and nitric acid. 3. Alkalis taste bitter and feel soapy or slippery. 4. The common alkalis found in the laboratory are sodium hydroxide solution‚ potassium hydroxide solution‚ calcium hydroxide solution and ammonia solution. 10.2 Acid-Alkali Indicators 1. An acid-alkali indicator

(review) Simple 1‚2-alkenes can be described as cis- or trans- (review) More complex alkenes are best described as E- or Z- based on the Cahn-Ingold-Prelog priority rules (review) Stability: There are 3 factors that influence alkene stability: 1. Degree of substitution: more highly alkylated alkenes are more stable‚ so tetra > tri > di > mono-substituted. 2. Stereochemistry: trans > cis due to reduced steric interactions when R groups are on opposite sides of the double bond. 3. Conjugated

Acids and Bases are two groups of chemical compounds that generally have opposite characteristics. They have there own unique traits‚ acids taste sour‚ turn litmus red while bases taste bitter and turn litmus blue. The term pH relates to measuring the acidity or alkalinity of a solution‚ such as vinegar‚ or even a damp substance like soul. The neutral pH is 7‚ which is essentially water‚ with lower numbers indicating acidity and higher numbers indicating alkalinity. Hydronium ions (H3O+) are
