Constant Density: Displacement of Zinc and Tin Introduction: Density is the concentration of molecules within an object on relation to its size. The formula for measuring density is mass/volume. In the experiment preformed for this lab report‚ calculating the density of a regular object (a wooden block) and two other irregular objects (zinc and tin) were found by a process known as water displacement. The purpose of this experiment was to prove that the density of an object remains the same

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

relationship between moles evolved and consumed. This can be demonstrated by 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.

Generations Have you ever thought about what it would be like to live in the past? The future? If one were to choose‚ are the future children going to be luckier than those that lived in the past conditions? 65 million people were born into the time period called “Generation Y.” Generation Y‚ who consists of those who were born between 1980 to 1999‚ are commonly compared to the Silent Generation because of the number of births. The Silent Generation is the generation of Americans born from roughly

It is really amazing to see what happened so far in this generation. Today‚ we have everything we ever wanted with the help of science and technology. Science and technology completely changed the way we function everyday. We have different kinds of drugs and medicine that saves a lot of people everyday. We have amazing electronics and devices that can do anything with your control. We also have media technology where we are connected to everyone around the world. When talking about the technology

FIRE RESISTANT BALLOON: Materials - 1 matchbox - 1 candle - 1 yellow colored balloon - 1 blue colored balloon - Half a cup of water Procedure: 1. For this experiment‚ the independent variable is whether the balloon is filled with water or not. The dependent variable is what happens to the balloon when it is placed above the lit candle. This is determined by observing the balloon. The constants (control variables) are how much the balloon is inflated and the amount of

What Would Happen If Half Of The Canadians Died? By Steffi Bael Have you ever wondered what would happen if half of the Canadians died? Well in the next few paragraphs I will be explaining what would happen. Hypothetically speaking‚ if half of the population in whole Canada vanished‚ definitely a severe suffering of economy would happen. We are all independent on our resources for living‚ natural and especially the human

What Happens in Narnia Does not Stay in Narnia We have all heard phrase‚ “What happens in the jungle stays in the jungle‚” or some variation of it. It can be a good way to dodge questions about your trip‚ or a quick way to tell people what happened without actually telling them what happened. It is common to hear this phrase in movies‚ and sometimes you may read it in a book. Many times this is a fun way to end a story‚ it leaves mystery. But what would happen if we actually talked
