Burning Marshmallow

When baking soda and vinegar mixes, a chemical change occurs. So how much baking soda, added to 10mL of compound vinegar( CH3CooH), will cause a film canister to shoot the furthest? I thought the answer to this question was 15mL of baking soda will shoot the lid of the film canister the furthest because there will be a longer reaction with more baking soda which will propel it far. This change happens because of they both have reactivity that causes the chemical change and shoots off the lid. The independent variable is the amount of baking soda and the dependent variable is how far the lid shoots. The amount of compound baking soda( NaHCO3) varied during several tests to see how far the lid would shoot from the end of the table to the back wall. Evidence that this reaction has taken place is the change in odor, color, and the appearance of gas or bubbles.

Endothermic reactions are accompanied by the absorption of heat. The dissolving of ammonium nitrate in water is an example of an endothermic reaction. The solution resulting from this mixture is colder than either the ammonium nitrate or the water. This is the simple explanation of what happens in an instant ice pack. The more detailed information will be discussed in the following paragraphs.

Experiment 2 focused on finding the enthalpy of solution of magnesium chloride. Testing the enthalpy of solution started with measuring out 10 mL of deionized water in a graduated cylinder for three separate trials, each trial having a different mass of magnesium chloride. The water was then poured into a well of a Styrofoam calorimeter then the initial temperature of water was taken using a temperature probe and the LoggerPro programming. A measured amount of magnesium chloride was placed in the same well as the water in the calorimeter,

The difference between endothermic and exothermic reactions is that endothermic reactions absorb heat, and exothermic give off heat. Dilution of ammonium chloride is an example of an endothermic reaction. This is the active ingredient in chemical ice packs you can obtain in a pharmacy. Other reactions are melting and boiling which also absorb heat to happen, although you may not consider them chemical reactions. Combustion is a typical exothermic reaction any type of burning.An exothermic reaction occurs if the energy of the bonds formed in the products

In part I, the ΔH of each individual reaction was obtained by performing each reaction inside a calorimeter. Temperature probes were inserted in the calorimeter and ΔT was measured. By using the equation q = Msol’n x Cp x ΔT + Ccal x ΔT, the heat absorbed by the surroundings, q, was obtained for each reaction. The negatives of these values, or heat released by the

On the first try, the lid traveled 396cm. I heard a big pop, there was not a leak or sizzle, and the lid took two seconds to pop off. The second attempt went 600cm. The lid took about four seconds to come off, there was not as big of pop, the canister leaked and sizzled a little and the cap hit the binders. The third launch for this trial shot 366cm. I shook the canister harder this time, there was a big pop, no leak, I did not hear a sizzle and the lid took about three seconds to fly off. The average distance for this trial was 454cm.

Marshmallows are sweet treat, but do you really know what happens when they heated up? The marshmallow was originally made up from the plant called Althaea officinalis. It was sometimes mixed with sugars or other ingredients. The modern campfire marshmallow that we will be using in our experiment is made up of corn syrup, starch, sugar, gelatin, and water, which are very normal ingredients and in this paper we will explain how they react to differing heat sources. First, we will measure the marshmallows for their circumference and height, and we will record this in our data table along with scent, texture and color. Then, we will be putting marshmallows in the oven, microwave, over an open flame, and in boiling water. These trials will be completed

In my lab,we observed various chemicals and their reaction to water.Their reactions were mostly that they just dissolved with the water,causing the water to turn white.However, some of their reactions were more interesting.One of the more interesting reactions was baking soda.At first the baking soda was chunky yet power like.When water was added however, it turned the water white, and caused it caused the water to bubble.The bubbles started off small, but soon grew in size. After the bubbles died down, there was a small sizzle, and the bubbles sank to the bottom of the specimen tray.The baking soda and a really cool reaction, and I must admit, I popped some of the bubbles with the paperclip. Something that did go wrong was that one of my

Question What will the outcome be if the amount of baking soda is substituted with an equal amount of baking powder in a standard chocolate chip cookie?

The marshmallow Experiment is a concept based on the famous saying “patience is a virtue.” In my opinion I can compare their choice of snack they chose to wait for to something I might really treasure or want at this point in my life. This experiment predicts that the children who decided they could wait longer to get two marshmallows instead of just one, are proven to be by far more successful in their futures.

Hypothesis: If the temperature of the chip rises, the temperature of the water above it will absorb some of the energy released by the endothermic reaction of the burning potato chip. Raw Data/ Results/ Observations: An increase in the mass of the potato chip resulted in an increase in temperature change, with the height of the water above the flame produced by the burning chip remaining constant. Although there was ½ gram more water in the second experiment, the

We already knew that exothermic means to exit or release heat energy. Endothermic means to absorb heat energy. Chemical reactions are when one thing changes into another but it cannot return to it’s original form. We read about instant hot packs and cold packs and how they are chemical reactions. When water mixes with different salt or some substances it can cause a decrease or increase in temperature. In our experiment our guiding question was which of the following substances would make an economical hot pack or cold pack? This goes to show how you can use your background information on endothermic and exothermic also chemical reactions to make and economical cold pack or hot pack you would have to think through what substance would work

We will be using 6 different fuels to heat up 100ml of water, and find out the changes of the temperature. We will measure the temperatures of the water before and after the experiment. We will burn heat the water for exactly 2 minutes, and check the changes in temperature. The change in temperature will allow us to work out the energy given off the fuel by using this formula:

Introduction: The theory behind this experiment is the heat of a reaction (∆E) plus the work (W) done by a reaction is equal to

Introduction: Every chemical change is accompanied by a change in energy usually in the form of heat. If heat is evolved, the reaction is exothermic, and if heat is absorbed, the reaction is endothermic. The energy change of a reaction that occurs at constant pressure is called the heat of reaction or the enthalpy of reaction (ΔHr). This quantity of heat is measured experimentally by allowing the reaction to occur in a calorimeter. In this experiment you will determine the heat of neutralization when an acid and a base react to form 1 mole of water. In a perfect calorimeter, heat is exchanged only between the reaction and the calorimeters water. Technically, some heat may may be absorbed the calorimeter. All calorimeters exchange some heat with its environment. This amount of heat is called the calorimeters heat capacity (the amount of of heat required to raise its temperature 1∘Celsius). We are going to “pretend” that our calorimeter is the perfect calorimeter.
