Research question/Aim Extract copper from copper oxide by reduction using butane gas Hypothesis The butane gas will reduce the copper oxide and leave behind pure copper. This will allow us to find the empirical formula of the copper oxide as well as the masses of oxygen and copper Variables Dependant variable The dependant variable will be the reduction of the copper oxide which will be calculated at different temperatures. Independent variable The independent variable here

(objective/subjective) would you expect to find? What test(s) are done to help provide a definitive diagnosis? o Well to begin with‚ I would want to ask the patient to rate his/her pain. For an acute episode‚ the best medication to treat with is analgesia. Morphine sulfate is given to relieve pain and reduce ureteral spasm (LeMone‚ 2015‚ P.758). o Other assessment data I would expect to find is complaints of flank‚ back‚ or abdominal pain. Radiation‚ characteristics and timing‚ aggravating or relieving factors. Has

The Effects of Dehydration and Hydration Water is a necessity in our world today but especially involving the health of human beings. Water is so important to human life that we would not survive without it because people become dehydrated when an insufficient supply of fluids are consumed in a day. “Human survival is dependent on water -- water has been ranked by experts as second only to oxygen as essential for life” (“Health Benefits of Water”). Proper hydration and the avoidance of dehydration

artificial nutrition and hydration (ANH) allows the provision of complete nutrition to patients who in the past would not have received such treatment. However‚ the wisdom of administering long-term ANH to every patient who can no longer eat independently is debatable (Peck et al 1990; Meyers and Grodin 1991; Hodges and Tolle 1994) and decisions around its use at the end of life have raised significant clinical‚ ethical‚ and legal concerns

Determining an enthalpy change of a displacement reaction Aim: To determine the enthalpy change for the displacement reaction between zinc powder and copper (II) sulphate solution. Zn (s) + Cu2+ (aq) → Cu2+ (s) + Zn2+ (aq) Theory: For the displacement reaction‚ an excess amount of zinc powder is added to the measured amount of aqueous copper (II) sulphate. The temperature change over a period of time has to be measured and thus‚ the enthalpy change for the reaction can be measured. The equation

1. A serving of two cookies has 150 kcal and 12 grams of fat. What percentage of total calories is fat? Divide fat calories by the kilocalories Fat – 9 kcal 12g x 9kcal= 108 kcal 108kcal / 150 kcal = .72 .72 x 100 = 72% total calories from fat 2. How many grams of protein are in a 2400kcal diet with 15% of total kcal from protein? Grams / total kcal = total percentage of kcal from the protein Protein – 4kcal X / 2400kcal = .15 (15%) 2400kcal x .15 = 360 360 / 4kcal= 90 gm of
