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

My Singular Irene Literature is‚ by my understanding‚ a means to critic society and individuals or the way the world is behaving. Writers of Literature write literature to provide a new way of seeing things that might be different from our point of view. In other words‚ writers use tools of literature story like: symbolism‚ point of view to help them is making the literature story to be more exciting and clear to us‚ the reader. The author helps us to see the frailty or other bad deeds and

Grass Decomposition Lab Problem: How do temperature‚ sunlight‚ amount of moisture‚ and presence of oxygen affect the decomposition of grass? Controlled Variable: Amount of grass and water in each container. Independent Variable: temperature‚ sunlight‚ amount of moisture‚ presence of oxygen. Dependent Variable: decomposition rate of grass. Hypothesis: I believe that there will be the most decomposition in high temperatures‚ low sunlight‚ low amount of moisture‚ and high presense

The Decomposition of Baking Soda Purpose: - To determine the correct balanced equation for the decomposition of baking soda using % yield. PreLab Notes: Sodium Bicarbonate (Baking Soda) decomposes when heated yielding both gaseous products and solid products. The production of gas makes baking soda a leavening agent in baked goods. The trapped bubbles of gas give muffins and cakes a lighter‚ airier texture. When heated‚ baking soda decomposes in one of the following unbalanced equations.

Synthesis and Decomposition of Zinc Iodide Partners: Sonya Pasia and Kristen Kobayashi CH 085-01 20 September 2011 Zinc Iodide (ZnI2) was an interesting binary compound to experiment with. In this experiment‚ weakly acidified water (25mL distilled water with 18 drops 5M acetic acid solution) was used as an aid to bring molecules of the zinc and iodide atoms together‚ by dissolving iodine molecules‚ so that bonding would transpire to produce a reaction. Deprived of water‚ the Zn and I2

As children we spent most of our lives exploring and learning new things with the help of our parents. There are some memories very vague but others that we will remember for the rest of our lives. These memorable moments could be the simplest to most complex things but as children they were a big deal to us. A childhood journey that I find extraordinarily memorable was the time I went to England with my parents because I traveled across the globe and I experienced different adventures. The time

Decomposition of Sodium Chlorate Mass‚ Moles‚ and the Chemical Equation Introduction: Sodium chlorate is used as a source of oxygen in emergency oxygen generators. So-called oxygen canisters or oxygen candles are found on airplanes‚ submarines‚ even the space station–anywhere where oxygen might be in short supply in case of an emergency. Sodium chlorate decomposes upon heating or in the presence of metals to give oxygen gas. What the chemical equation for the decomposition of sodium chlorate

downs‚ but throughout all this time‚ life has survived. Tragedies have happened here and there‚ almost completely wiping out all lifeforms‚ yet here we still are. I believe that all life forms are related in some way and that we all started out as singular cell organisms. After years of evolution‚ these single cells evolved into something greater‚ all life forms that we know today. It is because of this common ancestor that has caused most organisms today to be related‚ some closer than others. Typically
