The SI measurement unit is a unit that is used in science which is the most useful and dominate in this field. Other measurement units such as the metric system aren’t as useful as the SI system when it comes to being used in science. The metric system doesn’t have moles or kelvins‚ which are very important in the use of science. There are many more reasons why the SI system should continue to be used in science for measurement‚ and I’m going to explain why. National governments adopt one system

Lab 7: Catalysts Introduction Pre-Lab Questions 1. What is a catalyst? An enzyme is a biological catalyst that speeds up chemical reactions in the body. 2. If you continue to add more catalyst will the speed of a reaction always continue to increase? Explain your answer. It will continue to speed up the reaction until there is more catalyst than the limiting reactant. 3. In this lab you will produce oxygen and water from hydrogen peroxide (H2O2). Write a balanced reaction equation for this reaction

Lab 2: The Metric System and Microscope Name _________________________ Date __________________________ Section 1: The Metric System The Metric System is known as the International System of Measurement. The Metric System is based on Standard-prefixes that correspond to ‘multiples of 10’. The measurements of volume (the liter)‚ mass (the gram)‚ and length (the meter) are the baseline for all metric unit conversion factors. In the United States‚ the English System is more commonly used;

Name Date Lab: Denisty – Solids and Liquids Part 1: Density Background Information: The density of an object is how much “stuff”‚ or molecules‚ a substance is made of. Density is how tightly packed the molecules are. To calculate the density of a substance we need to know the mass (weight) of the substance and the volume (how much space) of the substance. Mass is determined by weighing an object. Volume of regular shaped objects is calculated by measuring

In this lab‚ we were able to determine measuring the pH of liquids work. We were able to compare the liquids based on their pH level and determine which liquid was acidic or basic. Our results showed that if something came out to be seven or less‚ according to the pH scale‚ it means that an acid is a substance that donates hydrogen ions. Because of this‚ when an acid is dissolved in water‚ the balance between hydrogen ions and hydroxide ions is shifted. Now there are more hydrogen ions than hydroxide

Provide a considered response to the following statement‚ “The principles and rules for risk management appear to be just plain common sense.” First we have to define what common sense is. Common sense is the everyday understandings and it based on everyday experience. It is a model of how the world works that we build up from our experience for example like personal or social experience. We can refer the common sense as market dynamics because market keeps changing through time. However it shares

The Metric system Have you ever looked at the back of a food item or drink to check nutritional values? Everything on the label is measured in the metric system. Do you actually know how much sugar you are getting? Or how much of a certain medication you can safely take? Have you ever thought that there should be ten inches in a foot‚ ten feet in a yard? A system with a standard that makes sense. Well you’re in luck with the metric system. The English Imperial system may be more familiar and
