student‚ and soon to be registered nurse was when I was administering medication last week on a respiratory floor. I had given my patient the medication‚ and realized there was no water at the bedside. I quickly went to get my patient water for her to swallow the capsules more easily from the bathroom. When I arrived back‚ she stated that she had already taken them. I had informed my preceptor and she advised me to look on her bed or the floor to see if she had discarded them there. We had looked around

ACIDS 1. Acids are chemicals which will turn litmus paper red. Litmus is a colored Chemical which can change from red to blue and back again. Which colour it is Depends upon the concentration of Hydrogen ions. If the concentration of Hydrogen ion is higher than it is in pure water then the litmus will turn red. If it is lower than in pure water the litmus will turn blue. 2. An acid is a substance that turns blue litmus paper red acids can‚ be identified due to specific

Higher Chemistry Mole Calculations Moles and Number 1 mole of any substance contains the same number of atoms/molecules/ions as there are atoms in a 12g sample of carbon -12 12g of carbon-12 contains a constant number of atoms. This number is known as the Avogadro constant (L) and is equal to 6.02 x 1023. 1 mole of carbon-12 contains 6.02 x 1023 atoms. Therefore‚ 1 mole of any substance contains 6.02 x 1023 atoms/molecules/ions. For example‚ 1 mole of aluminium contains

INVESTIGATION #2 DETERMINATION OF THE WATER OF CRYSTALLISATION April 4‚ 2012 OBJECTIVE: Chemical compounds that contain discrete water molecules as part of their crystalline structure are called hydrates. Hydrates occur quite commonly among chemical substances‚ especially among ionic substances. More often than not‚ such compounds are either prepared in‚ or are recrystallized from‚ aqueous solutions. Hydrates exist for ionic compounds most commonly‚ but hydrates of polar and non polar covalent molecules

Subject: Chemistry Topic: The Periodic Table The periodic table is a classification of all the elements based on ATOMIC NUMBER. It is composed of HORIZONTAL PERIODS and VERTICAL GROUPS which contain the elements arranged: *the order of INCREASING ATOMIC NUMBER *in the relation to the ELECTRON STRUCTURE of the atoms *in the relation to their CHEMICAL PROPERTIES (Criteria Used For Placing ELEMENTS in the Periodic Table) 1. ATOMIC NUMBER 2. NUMBER OF SHELLS (PERIOD) 3. NUMBER OF OUTER

Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this‚ we placed the physical elements in a 24 well plate‚ dipped wet q-tips into the wells to gather the element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of

bulb is filled with argon‚ krypton‚ neon or xenon and low pressure mercury vapor. The inside of the tube is then coated with various blends of metallic and rare earth phosphor salts. The cathode tube in the bulb is made of tungsten and is coated with barium‚ strontium and calcium oxides and evaporation of the organic solvents is allowed‚ after which the tube is heated in order to fuse the coating to the lamps.

without a transitional host. The cycle of the infection is initiated when a human swallows the parasite either through contaminated water of food in the oral cavity. The parasite is covered in a cyst‚ which is protective shell that surrounds the organism offering protection and allows it to survive when it is outside an animal or human host. It takes approximately 10 to 15 cysts of G. lamblia for a person to swallow in order to be infected. The cyst is oval shaped and consists of a smooth wall. When
