Lecture No. 1 Chemical Kinetics 1.1 The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate

Chemical Reaction:- The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance. (b) Change of colour of substance

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚

Physical assessment is one of the process to assess and obtaining information about a patient’s health history and family medical history which can help in planning a patient’s care. A nurse uses subjective and objective data gathered to assess patient and the five nursing process to conduct patient’s health care. Interviewing patients is the first step. This paper discusses the health history of a lady I interviewed known as Mrs. E‚ family medical history‚ and overall reflection of the interview

Chapter 6: Chemical Bonds Section 6.1: Ionic Bonding Chemical bond: the force that holds atoms of elements and ions together to become a stable‚ new substance called a compound. -the number of valence electrons determines if an atom will form a chemical bond. -metals tend to give up electrons to other atoms. -nonmetals tend to take electrons from other atoms. -noble gases will not form a chemical bond because these atoms already have a full outer shell of energy.

Physical Education 2014 Terms and Definitions Agonist and Antagonist – these are terms for muscles‚ which work in pairs. Agonist – is the muscle‚ which is the prime mover and creates the initial movements via contraction e.g. the bicep is the antagonist muscle‚ when you pull your arm towards you bending at the elbow. Antagonist – is the muscle‚ which relaxes to allow the movement to occur e.g. the triceps will relax to allow your arm the bend at the elbow. Flexion – decreasing the

Physical development is the way the body increases in skill and becomes more complex in performance. Physical development is divided into two main areas which are Gross Motor Skills and Fine Motor Skills. Gross motor skills involve co ordination and control of the large parts of the body. Some of the movements that are included in gross motor skills are walking‚ running‚ jumping and climbing. Fine Motor Skills relate to the control of the smaller muscles ‚ controlling finer movements such as pointing
