When the Pop Rocks come in contact with the soda, the gas in the Pop Rocks escape after
The topic of research is, “how fast does an Alka-Seltzer tablet make gas?”. In the experiment, the scientists will be measuring the chemical reaction rates that occur, when 1 Alka-Seltzer tablet is placed in a specific temperature of water. The independent variable during the experiment will be the temperature of the water (degrees Celsius). The dependent variable during the experiment will be, the rate in which gas is produced (in seconds). The constants of the experiment, will be the amount of water used and the Alka Selter compound. The control in the experiment is water. Units used while timing the productivity of gas from an Alka-Seltzer tablet in different temperatures is, seconds.
Alka-Seltzer is something that when it gets put into water it has a chemical reaction because it starts to bubble up and when it starts to bubble up the bubbles are carbon dioxide gas.
An Alka-Seltzer tablet is a medicine tablet made with baking soda used as a pain reliever for “headaches, body aches, pain, heartburn, acid indigestion, and sour stomach” (Alka-Seltzer Tablets). It is put into water, left to dissolve and then consumed. When an Alka-Seltzer tablet is dropped into h20, a chemical reaction immediately takes place and produces bubbles made out of carbon dioxide as a product of the collision (Olson 2). When in its original powder (dry) form, the Alka-Seltzer’s two main ingredients: citric acid and sodium bicarbonate are just there and not reacting to each
The topic that the scientist has researched is the reaction rate of different particle sizes. In the experiment, the scientist will discover how the particle size of Alka Seltzer affects the rate of chemical reaction with water. The independent variable in the experiment is the particle size of the Alka Seltzer, while the dependent variable is the rate of reaction, or the volume of Carbon dioxide. The volume of carbon dioxide will be measured in ml. Also, a few of the constants in the experiment will be the amount of water, and amount of tablets.
Procedure: Begin by measuring the mass of the empty beaker. Then, place 2.00 grams of baking soda into the empty beaker. Using the tongs put the beaker filled with 2.00 grams of baking soda onto the hot plate. The beaker needs to be heated for about ten minutes. Remove any clumps throughout the ten minutes with the spatula.
Reaction 2: when sodium hydroxide (NaOH) is added to copper (II) nitrate (Cu(NO3)2), a double displacement reaction will occur. Copper and sodium will displace each other to create copper (II) hydroxide and sodium nitrate.
The Copper Cycle is a well-know experiment that is used to demonstrate the Law of Conservation of Mass. According to this law, mass is conserved during chemical reactions. In other words, the mass of copper in the reactants is supposed to equal the mass of copper in the products.1 The Copper Cycle is a series of 5 reactions over which the mass of copper is ideally conserved. These reactions are various types of reactions, which highlights that mass is conserved in all kinds of chemical reactions. However, due to experimental errors, some percent of copper is usually not recovered in the last step.
Our experiment consists of adding one tablespoon of baking powder to each two cupcakes. There will be ten cupcakes in all and two will be controls, without baking powder. We will figure out which cupcake is the most “perfect” meaning the most fluffy, its circumference and height will be measured. Baking powder contains sodium bicarbonate, dry acid, and cream of tartar. These ingredients chemically changed out mixture into cupcakes. The powder makes bubbles that occurs immediately after adding liquid-based ingredients. While in the oven, it produces a chemical reaction that also creates bubbles to make the mixture rise. It changes the cupcakes identity and the form because the baking powder produces a carbon dioxide gas. The powder is broken
Chemistry is one thing that makes us understand and gives us reasons of why certain reactions gives certain results. In this experiment we will be illustrating the reaction between baking powder and vinegar and see what happens to the balloon that is attached to it. Hypothetically the reaction of the vinegar and baking powder will produce carbon dioxide which will inflate the balloon. If the more vinegar may happen that when more vinegar is added to the baking powder it may produce more carbon dioxide thus the balloons diameter increases. This reaction is an acid base reaction thus results expected to show some carbon dioxide.
The CO2 gas produced can be used as an indicator for the rate of reaction as the amount of CO2 gas that is collected with in a fixed time is proportional to the rate of reaction. Therefore, the average rate of reaction can be calculated by measuring the amount of CO2 collected for a set period of time.
Added mass (clay, baking soda, vinegar) was 31 while the final was 30. We left eh bag open a little to pour in the vinegar and a little of the air gas had time to escape. Those three signs are known as signals of when substances combine in a chemical change to form one substance (so we can prove our explanation was a chemical change). The Law of Conservation of Mass states that matter cannot be created or destroyed, supporting our claim that matter cannot change in a closed system. In our experiment the mass changed from the beginning and end, meaning that mass must have escaped. During our experiment was had to have the bag open for a second at the beginning giving the gas time to escape and with it, its mass. This caused the mass the be
Plot a graph of product concentration vs. time and then use the gradients of the 7 test tubes to determine the velocities of the reaction.
There are several factors which affect the rate of reaction: catalyst, reactant concentration, and temperature.1,2
This experiment uses baking soda as a flame retardant. How exactly does baking soda work as a flame retardant? This is because when a fire starts, it
