4D: Process information from secondary sources to investigate the relationship between the volumes of gases involved in reactions involving a metal and relate this to an understanding of the mole. METALS Reacting Gas Volumes AIM: to investigate the relationship between the volumes of gases involved in a reaction. HYPOTHESIS: A new gas will form when two gases will react together. BACKGROUND INFORMATION: Nitric oxide and oxygen are both colourless gases which do not dissolve in water

Mining is the process of digging beneath surface of the earth and extracting minerals and other useful geological materials. There are two main categories that mines fall into; surface mines and underground mines. Surface mines are effective at extracting minerals and geological materials that are close to the surface of the earth while underground mines are designed to extract minerals and geological materials that are deep beneath the surface of the earth. One of the most common materials that

COST-VOLUME PROFIT (CVP) ANALYSIS This is a technique used for planning short-term run profits by finding the relationship between profits and factors that influence profits. The following factors are taken to be influencing profits:- • Selling price • Variable cost of production • Fixed costs • Activity level (production and sales units) Profit planning is based on break-even analysis and can be worked out using either; a) Algebraic method b) Contribution method c) Break-even

integration through hormones. In this chapter‚ you will learn about the neural system of human‚ mechanisms of neural coordination like transmission of nerve impulse‚ impulse conduction across a synapse and the physiology of reflex action. 316 BIOLOGY 21.1 NEURAL SYSTEM The neural system of all animals is composed of highly specialised cells called neurons which can detect‚ receive and transmit different kinds of stimuli. The neural organisation is very simple in lower invertebrates. For

Previously she seemed to have age-appropriate social skills‚ interacting well at school. Her withdrawal started suddenly. Mariella’s teacher‚ Mrs. Levine‚ called Mariella’s mother to find out more information‚ but her

Experiment 6 Mole Ratio in a Chemical Reaction Background: Mole ratios of reactants are often times figured out by the use of the other products in a chemical equation. However‚ in the instance that the products’ mole ratios are unknown‚ it can be determined through the experiment. This method is called continuous variations. In this lab‚ I determined the mole ratio between Sodium Hypochlorite and Sodium Thiosulfate by using continuous variations of ratios in a given volume. This reaction was
