investigation: The speed of a metal carbonate breaking down depends on where the metal is in the reactivity series. The more reactive a metal is the slower it takes for it to breakdown. The less reactive a metal is it breaks down faster. Explain the hypothesis using scientific ideas: The metal carbonate which is lower in the reactivity series such as copper can thermally decompose much faster because it is the least reactive metal so its an unstable carbonate and the bonds are much weaker. So

Phuong Pham Prof. Johnson Lab 3 Gravimetric determination of Calcium as CaC2O4.H2O Feb‚ 27‚ 2014 I. Objective: The purpose of this lab is to determine how well gravimetric method measures the calcium level in a solution of known calcium concentration. II. Method: a) Overview: In this lab we will prepare 25 mL known concentration Calcium solutions. Then we will use Gravimetric method to determine the concentration of Calcium in each solution to figure out how well this method is. As we know

concept of “victim precipitation”. This theory views the victim as a participant in a crime. This is analysed in two ways. The aggressor and the provoked. Victim precipitation is defined as the extent to which the victim may have contributed directly or indirectly to their own victimization. The concept is that victimisation involves the victim and the offender‚ and it is the action and reaction of the parties that has lead one of them to become a victim. Victim precipitation is a behavioural idea

Investigating the rate of reaction between Marble Chips (Calcium Carbonate) and hydrochloric acid Aim. In the investigation I am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small/large pieces of Marble Chips (Calcium Carbonate) and Hydrochloric acid per minute. Hypothesis. The rate of reaction increases when the surface area of a solid reactant is increased. This happens because by

AIM: To carry out a lab experiment to decompose a carbonate using heat‚ also to carry out appropriate tests for the formation of products as a result of this decomposition. DISSCUSION: Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide. The temperature of decomposition depends upon the activity of the metal; that is to say‚ the more active the metal‚ the more stable is the carbonate. Thus‚ the carbonates of sodium and potassium are stable at the highest temperature

EXPERIMENT 4 TITLE Complex Formation and Precipitation. INTRODUCTION Precipitation is the formation of a solid in a solution as the result of either a chemical reaction‚ or supersaturating a solution with a salt resulting in solid material collecting on the bottom of the beaker (Housecroft & Constable‚ 2006). When the solution has been supersaturated by a compound and no more material can be supported by the solution‚ it considered as precipitate. Commonly‚ the solid will fall out of the

This experiment will consist of two islands‚ Darwin Island‚ Wallace Island and take only into account the bird population of these two islands. The parameter will stay the same‚ except for one variable; precipitation. I will record how the precipitation changes the beak size of the bird population
