In this video we learn how to balance chemical equations properly. What is a chemical equation? It's a statement that uses a chemical formula to show identities and relative amounts of the substances involved in a chemical reaction. To balance an equation out you must have the same number of atoms on both sides of the chemical equation. Or, you must have the same amount of mass or matter on both of the sides. Once you have these balanced out so they are the same then you will have it complete...
In this video, we learn how to properly balance chemical equations. You will see what substances are in each side of the equation. You will then need to count the atoms that are on each side of the chemical equation. Once you write down the number of atoms on each side, you will need to even them out. To do this, you need to change the coefficients within the equation. These change the total number of atoms inside of a chemical. Once you do this, you will add more to each atom present and the...

In this video we learn how to balance chemical equations using a teacher's guide. A chemical equation is a brief way of summarizing what happens inside of a chemical reaction. When you mix up two different chemicals, they will create new types of chemicals in the equation. You have to take these new chemicals into equation when you are trying to balance it out. The mass on both sides must be the same as well as the number of different chemicals on each side of the equation. Try out practice e...

The first problem that is show is exponential decay. First you will need to create a table with hours and substance left. The next step is to find the trend by noting that we are left with a certain percentage of the substance. One you have the trend you will use this to calculate the amount of substance left in said hours, in this case 6 hours. The following example shows you how to solve exponential growth. It is essentially the same except for the fact that you will be increasing, so inste...

n this tutorial, we learn how to balance chemical equations. This is a straight-forward concept to balance out both sides of the equation of chemicals. To start, you will need to analyze how many atoms in each chemical you have on each side. Once you do this, you will need to find what you can multiply by on each side to make them equal to the other side. Once you do this and have equal atoms on each side, then the equation will be equal. Remember that you cant have a half of an atom, so that...
Students show how mercury thiocyanide or "rock from mars" burns. First and foremost, make sure you are outdoors and with a considerably large space. Spread a non-flammable material over the space you decide to work on and place a small fragment of the mercury thiocyanide in the center. Keeping a respectable distance from the "rock" touch the "rock" with a lighted match. Watch as a substance oozes out from the rock. Make sure that the process has ended or that no movement can be seen from the ...
Olivia and Andrea created a song to the tune of "I'll stand by you" by the Pretenders to teach you how to balance chemical equations. A chemical equation requires coefficients in order to be balanced. You can balance a chemical equation by making use of the Periodic table. The example reaction in the song is that of aluminum and oxygen to produce aluminum oxide (Al + 02 -> Al203). You can systematically add coefficients to the reactants and products to balance the equation. A chemical equatio...

In this video we learn how to understand chemical change in Chemistry. When you start out, you must first figure out what your cathode and anode is in the equation. Then, read it out to find out if it's oxidized. Once you have this figured out, you can find the conditions of temperature you need to maintain the chemicals. You can figure this out b doing a basic equation for all of the chemicals. Fill this in with the correct information, then the answer will be done. Make sure you understand ...
In this video, we learn how to balance chemical equations with ease. First, you will need to take down the equation and find out how it is formed and how much each of the chemicals are in it. Draw a diagram if you need to so you have a visual key. If you figure out how many of each of the chemicals are in the equation, then you will know how to balance it out. You will make sure that both the right and left have the same number of chemicals and mass. Balance this out by adding in more chemica...
In this video, we learn how to balance chemical equations using a simple method. Start out by writing your two chemicals next to each other. After this, you will need to write out how much of each atom each of the chemicals has. Now you will have a better idea of how you need to balance out each of the different equations. Make a chart of all the elements that are involved, then you can solve it. Use simple addition to add together the atoms of each and then write out the correct answer in th...
In this video we learn how to balance chemical equations the fun way. First, remember that matter cannot be created or destroyed. Take two different types of chemicals and put them on opposite sides of the equation. If you have more mass on one side than the other, these will not balance out. Once you have equal amounts of mass on both of the sides, you will be able to balance the chemical equation. Remember this rule whenever you are balancing out chemical equations. Use visual markers to he...

In this tutorial, we learn how to balance chemical equations. The first thing you want to do is to draw a graph and label one side reactants and the other side products. Go through each of the atoms that are in your equation on both sides. Write out how many atoms are in each chemical. Then, find a common multiple that will give you and equal amount on each side of the equation. Continue to do this same for all the chemicals in your equation, then when you are finished write it out. Now you w...
Oobleck, a word coined from the Dr. Seuss book "Bartholomew and the Oobleck," has contemporarily come to define the substance created from mixing cornstarch and water. This mixture is notable for its dilatant properties, and as an inexpensive and non-toxic Newtonian fluid. While seemingly liquid, under pressure, the substance reacts as a solid. Gentle treatment, however, will allow the material to remain in its fluid state. More simply put, this sh*t is crazy.
When it comes to trimming your dog’s toenails, there are several instruments you can use. In this video, Patrice introduces you to the toenail clipper and the toenail grinder.

This video illustrates how to make napalm. You will need a petri dish, gasoline, and styrofoam to create napalm. Combining the styrofoam and gasoline in a petri dish you allow the styrofoam to dissolve and become a semi-solid substance. It will have the consistency of chewing gum and it will be highly flammable. This substance will be sticky and if lit it should be lit outside and at a distance from anyone as it will produce a gas that is toxic.
On this episode of Scientific Tuesdays, Dylan shows you how to create a non-Newtonian fluid using corn starch and a little water. A non-Newtonian fluid is any fluid that does not follow the laws of physics.

This is a video tutorial in the Education category where you are going to learn how to describe chemical formulas. A chemical formula represents the actual number of atoms of each element within a molecule. Different visual representations of molecules include the ball and stick three dimensional model, a line drawing that represents the structure in two dimensional terms, and a shorthand used by organic chemists. If a molecule has 4 green atoms and 2 orange atoms, the ratio of green to orang...
snow mold occurs in round patches of grass in the lawn. The patches contain a fussy substance (the mold), that appears in grey or pink; the most dangerous of the two. Mold is formed whenever a lot of snow is left on the lawn for a long period of time, this causes the mold to grow underneath. Late fertilization with a lot of nitrogen promotes mold. Dead grass or thatch can cause mold to develop. Gently raking allows airflow into the grass and promotes new grass growth. The putting down of gras...
