Dystonic Reaction Dystonia is a condition that makes your muscles contract without warning (muscle spasms). It can cause unwanted jerking of muscle groups that can be uncomfortable. This condition is rarely life threatening. CAUSES A dystonic reaction is most often a side effect to a particular medicine. These reactions occur when the normal patterns of the nerve receptors are upset by a particular medicine and the imbalance causes multiple types of muscle spasm. This condition may also be caused

ADVERSE DRUG REACTIONS Lecture by Dr.Shehla Shaheen Adverse effect is a harmful and undesired effect resulting from the administration of a therapeutic dose of a drug. OTHER WORDS USED SYNONYMOUSLY; SIDE EFFECTS TOXIC EFFECTS HARMFUL EFFECTS UNDESIRABLE EFFECTS All drugs can produce harmful as well as beneficial effects. ADRs are either related or unrelated to the principal pharmacological actions of the drugs Adverse effects are of great concern to drug regulatory authorities.

Introduction Nivaldo J. Tro describes kinetics as the study of how changes that occur in chemical reactions take place over time‚ and because of its vast utilization in a multitude of industries‚ it may be one of the most significant and fascinating aspects in the entire chemical world. One application of the study of kinetics can be applied to the determination of the rate of a chemical reaction involving a certain selection of chemicals (FD&C Blue #1 and sodium hypochlorite). The purpose of the

is being released or absorbed in a chemical reaction. My lab partner and I had to determine the heat exchanged when solid magnesium hydroxide is mixed with solid citric acid‚ using a coffee cup calorimeter. Given that citric acid is soluble in water is the property that makes this reaction possible. The first law of thermodynamics and Hess’s law are also present within this experiment. Knowing the difference between endothermic and exothermic reactions is also relevant. If the temperature goes down

In Reaction 1‚ the mass of the pre-cut copper wire was measured with watch glass on the analytical balance‚ the mass was recorded using as many significant figures as possible on Table 2. The copper wire was bended into a circle and laid flat on the bottom of the 250 mL beaker. Inside the fume hood‚ 4mL 16M of HNO3 was added into the 250mL beaker that contained the copper wire. The copper wire was completely dissolved by swirling the beaker. The observation was recorded in Table 3. For Reaction 2

Chemical Reactions Lab Synthesis Reactions: Synthesis reactions occur when two elements or compounds combine to create one single compound. The general equation of synthesis reactions is: A+B→AB. The following are the complete balanced equations for the five synthesis reactions performed in the lab. Reaction 1: Reaction 2: Reaction 3: Reaction 4: Reaction 5: The reaction of CO2 and water is a prime example of a synthesis reaction. This is a synthesis reaction because it follows the general

entering World War II‚ until the bombing of Pearl Harbor. Government funded atomic weaponry research had begun not long before the attack‚ and this has led people to believe that the Manhattan Project‚ a descendent of the program‚ was a knee-jerk reaction to the bombing. According to writer Brenda Wilmoth Lerner in her article on the Manhattan Project for the Encyclopedia of Espionage‚ Intelligence‚ and Security‚ Roosevelt ordered‚ in December of 1941‚ that research was to begin regarding the plausibility

Bags of Reactions * Problem/Purpose * Background Information: The Law of Conservation of Mass was created by Antoine Lavoisier in the 18th century. This law stated that mass could matter could neither be created nor destroyed. During a reaction the bonds of the reactants are broken and form new substances. As stated in the Law of Conservation‚ matter can neither be created nor destroyed; because of this the products should have the same number and type of atoms as seen in the reactants

Analysis of a Chemical Reaction Purpose: To observe a chemical reaction and to use qualitative and quantitative evidence to identify this reaction from among four possibilities. Hypothesis: I think the result is going to produce water. I think this is going to happen because there is hydrogen and oxygen inNaHCO3. Materials: -Test tube clamp - 150 mm test tubes (2) - burner - retort stand - clay triangle - iron ring - crucible Procedure: Part A: 1. Add 0.5 g of NaHCO3
