Substance abuse and substance dependency are more alike than they are different because they both involve the overindulgence in illicit drugs or alcohol. Substance abuse seems to be the stage before dependency being that one has to excessively use the drug in order to become dependent. Once a person becomes dependent on an illicit substance they are prone to becoming functioning addicts where the abuse is ongoing. The only real difference between the two is that substance dependency allows one to

measuring the hydrogen gas evolved by performing a chemical experiment when hydrochloric acid reacts with the magnesium. The formulated reaction includes; Mg + 2HCl → H2 + Mg2+(aq) + 2Cl- (aq) The major findings contributing to the experiment is being able to determine and distinguish what moles have evolved thus being the hydrogen moles evolved allowing the magnesium to be consumed within the reaction. Procedure Step 1: Obtain a 600 mL beaker‚ and add 300 mL of water. Step 2: Add 30 mL of

Introduction: In liver cells‚ hydrogen peroxide is produced as a bi-product of some metabolic reactions. Hydrogen peroxide is a highly active chemical used in household products for bleaches and cleansing wounds. In a cell its build up would be highly toxic. However‚ liver cells contain an enzyme‚ catalase‚ which immediately breaks down hydrogen peroxide. It is a peroxidase and breaks up the toxic hydrogen peroxide to water and oxygen which are both nontoxic. The reaction is exothermic‚ meaning that

Abstract The decomposition of hydrogen peroxide (H2O2) in a whole and diced wedges by with The enzyme catalase was observed. The catalase was able to break down the hydrogen peroxide In the diced banana wedge better than the whole banana because after the banana was diced that Increases the surface area allowing the breakdown to flow. The effects of temperature on enzyme In a liver sample were observed under iced‚ boiling‚ 37 degrees‚ and room temperature Conditions. The enzymes became completely

17th century‚ French philosopher‚ Rene Descartes‚ proposed a revolutionary explanation of the notion that there is a separate‚ yet causal relationship between the mind and the body. Descartes created the school of philosophical thought known as substance dualism in which he methodologically elucidates his argument that there are only two fundamental entities in the world‚ that being mental and physical things. In his philosophical treatise‚ Meditations‚ Descartes challenges the Monist materialistic

Addiction will lead the individuals to have to chronic‚ relapsing‚ and compulsive behavior despite the known negative side effects.

As we are using enzymes and Hydrogen Peroxide we need to be extra careful‚ ensuring they don’t come into contact with our eyes‚ skin or clothes. Catalyse is an enzyme found in all living cells. It makes Hydrogen Peroxide decompose into water and Oxygen. We will be measuring the amount of Oxygen released from the Hydrogen Peroxide. In order to do this we will use a measuring cylinder.
