DIFFDiffusion of Chemicals * Diffusion-is the process whereby particles of liquids‚ gases‚ or solids intermingle as the result of their spontaneous movement caused by thermal agitation and in dissolved substances move from a region of higher to one of lower concentration. The rate of diffusion depends on the size of the surface area to the volume in the cell. The higher the surface area of cells in relation to their volume‚ the quicker diffusion takes place. Experiment on Diffusion Aim: to

A Critical Analysis of the Effects of Chemical Castration and Physical Castration on the Recidivism Rates of Sex Offenders Introduction This paper examines the effects of chemical castration and physical castration on the recidivism rates of sex offenders. Using theory integration or the multifactor approach‚ the findings reveal there are several factors influencing sex offender recidivism. Both chemical castration and physical castration have the potential to reduce the recidivism

Immanuel Kant’s moral theory can be best explained by comparing it to a math equation. Kant’s moral system will always hold true no matter what the circumstance just like how two plus two will always equal four. According to Kant‚ our lives should be lived according to maxims that can be willed into universal law (Kant‚ Fundamental Principles of the Metaphysic of Morals‚ p 303). However the action regarding a moral decision is not judged by the consequences of that action‚ rather by the motive

Thermodynamics is a branch of physical science in which deals with the relations between heat and other forms of energy. The ability to predict if a chemical reaction will occur spontaneously or non-spontaneously is an important aspect of thermodynamics. Spontaneity is determined from free energy‚ or Gibbs free energy. The equation (1) gives the relationship of how entropy (∆S) and enthalpy (∆H) along with temperature affects the amount of free energy‚ and henceforth the spontaneity. A spontaneous process

this problem. Firstly the causes of this problem is the attitude of human. The human attitude nowadays really disappointing. They do not have the love feeling to the nature and throw garbage or any chemical substances anywhere including the river‚ the sea and any water sources. So this chemical substance will harm the water and we as the user will use the water without notice that we use the contaminated water. Slowly or in the long term our body will be affected. Besides that. the excessive used

Assignment 5 Sheet Harbour Chemicals Sheet Harbour Chemicals (SHC) manufactures chemicals used in the paint industry. The process involves three departments. Chemical A‚ which is purchased for $3 per liter‚ is processed through Department 1 in batches of 100 liters. Each batch of chemicals processed through Department A produces 70 liters of chemical B and 30 liters of chemical C. Chemical B is sold for $10 per liter. Chemical C is used in Department 2 to produce chemicals D‚ E‚ and F. Department 2

Chemical Engineering In the future I would like to become a chemical engineer. I really enjoy chemistry and hands on work “Chemical engineering is the application of chemistry to large scale industrial systems.” (Chemical engineering). I enjoy helping build different things like skateboards‚ ramps and‚ fixing parts on different things. When I took the sixteen personality quiz it said I was a virtuoso. The virtuoso likes hands on work and exploring ideas which I think fits my personality perfectly

there are unfortunate couples that can’t have even one. If the woman is pregnant everyone is very excited towards the baby especially the father. But what if the baby in your womb that you thought you has is not actually a real one; but a cluster of H-mole. The fetus or developing baby‚ the placenta (or after-birth)‚ which has many functions including the feeding of the baby and the removal of its waste products. The placenta is made of millions of cells called trophoblasts. These two parts normally

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‚
