Apothecary: What Is A Projectile?

The experiment is to observe a variety of chemical reactions and to identify patterns in

First let's start with with something simple Chemical Changes most Chemical Changes take place on the molecular level. Chemical change produces a new substance. For example another way you can think of it is that a chemical change accompanies a chemical reaction grat examples of chemical change are combustion in other words burning, cooking an egg is also a great example of chemical change also rusting of an iron pan, but for a more detailed chemical change a great example would be mixing hydrochloric acid and sodium hydroxide to make salt and water.

One type of chemical reaction, called combustion, involves the burning of various compounds and elements. Some substances are more

In this experiment you will observe some physical and some chemical changes. You will observe that energy must be used to start some chemical reactions, and that it is produced in others.

A chemical reaction is a process that involves change of the molecular or ionic structure of a substance, as opposed to a change in physical form or a nuclear reaction. The key concepts of a chemical reaction are:

3. The “new” substances that were formed as a result of chemical change were many. When I took the candle and lit it, it burnt and formed smoke. When I took the wooden split and lit the paper on fire, the color around the green paper changed to be brown, burnt and changed into ashes. Also, I poured Hydrochloric acid and magnesium ribbon in a test tube and it started bubbling and it heated up in the bottom.

In this experiment it was observed that not all chemical reactions occur at the same rate. Chemical reactions occur when one or more substances are changed into other substances. The properties of a chemical reaction require three things. First, they need a source of energy for molecules to encounter each other. Second, they require to proceed at a steady rate. Third, they must proceed in a particular direction until they reach equilibrium. There are two types of chemical reactions that can occur: endergonic and exergonic reactions. In these reactions there are both reactants and products. In exergonic reactions the reactants (starting materials of a reaction) are higher than the products (results of a reaction). This is opposite for endergonic

Many signs show that a chemical reaction has occurred. Some ways we know there is a chemical reaction are the formation of gas, formation of precipitate, change in temperature, and,or change in color. In part one of the experiment, we know there was a chemical change because of the formation of the white precipitate. We poured the ammonia and water in the flask with alum and water, forming a white, cloudy substance in between the two liquids. The white, cloudy substance between the two is liquids is also known as aluminum hydroxide. The second part of the experiment was very similar to the first, but in the second part we mixed epon salt, water, and ammonia. The precipitate formed from mixing the epson salt, water, and ammonia was called magnesium hydroxide.

Chemical changes are often accompanied by physical changes. Three that you should not see in this lab are changes in temperature, presence of a flame, and evolution of light, as when as firefly glows. Three physical changes that indicate a chemical change may have occurred (and that may be seen in this lab) are:

The first thing to know for the project, is what a projectile is. A projectile is any object cast, fired, flung, hurled, pitched, tossed, thrown, or propelled in any sort of way, by an external force and continues in motion by its own inertia. A projectile is most commonly referred to as a missile designed to be fired from a rocket or gun.

There are five clues that help indicate if a chemical change occurs. The clues to a chemical change include a change of colour, the forming of a precipitate, the forming of gas bubbles, the production of heat or light, and if the change is difficult to reverse. In the chemical reactions lab, several chemical changes will occur. Participants must use this knowledge to decipher what change has occurred after the chemical

Chemical reactions make new things by rearranging other things. In a chemical reaction, the main change that occurs relates to the way atoms are bonded to each other, in order to change those connections, bonds must be broken and new bonds be formed.

Gunpowder, also known as black powder or #0027 to the U.N.,is a 1.1D class hazardous material known as low explosive. It has a specific flash point (point of ignition) of 427-464℃ (801-867℉), a specific gravity of 1.7-1.82 (mercury method), and a pH of 6-8. Gunpowder has changed so many times from its earliest form, and with its many forms came many uses.

caused it to spread around the world. Gun powder is made up of simply three ingredients. The ingredients to make gunpowder are potassium nitrate, common charcoal and sulfur. Ingredients to make gunpowder can be easily found at markets where chemicals are sold and no such identification is needed to purchase them. Potassium nitrate was first made up from decayed animal and then later on it came from mines in India. The common charcoal is made up from wood that has been cooked so no such gas is in it, all the gases are to be completely removed. Sulfur is the thirteenth most existing Element in the earth crust and it can be mined. Mixing the potassium nitrate, common charcoal and sulfur creates gunpowder, it 's not difficult to make it so in reality anyone can make it to cause damage to property or use it to their intentions. The outcome of the three chemicals being mixed together causes everything to turn black, once you 've reached the stage you know gunpowder is in your hands. The

But behind all the excitement of fireworks, chemistry plays an important role in creating the vivid colors we witness lighting up the sky. The actual chemical reactions that take place in the explosions
