Introduction This article reviews the technological use of exothermic chemical reactions that release their energy in a very short time interval. There are three primary fields of application for these effects:
There is some similarity. Like all equations, something has to be "equal. These values also exist at the same time like a balance. In a chemical equation the atoms on the left side have to be equal to the atoms on the right side of the arrow, but they don't exist at the same time.
The chemical equation represents movement.
For example, here we start with carbonic acid consisting of 2 hydrogen atoms, 1 carbon atom, and 3 oxygen atoms. The atoms rearrange and become water and carbon dioxide.
All original atoms are still accounted for. Chemical Equations are simple: Like I said earlier, atoms combine in simple ratios. That means the chemical equations that show and balance the starting "reactants" and ending "products" are fairly simple.
Unlike math equations, chemical equations are showing a progression of time. Here we see how hydrogen and oxygen reactants react and produce water. It's a simple rearrangement.

It's also easy to see how many wheels are necessary to build them. Because this is very visual and atoms are too small I'm going to use the manufacturing of these products as an introduction to balancing chemical equations. This company is going to promote their super durable tires.
The tires will be the biggest expense in making these cycles. Because of that, the company may recall cycles that aren't celling and put the wheels on the cycles that are selling.
Notice that the wheels are only sold to the manufacturer in pairs. The company that produces these pedal cars can use abbreviations similar to the way chemistry uses abbreviations.
For example Cb can represent the "Car body". So "W2" repesents a pair of wheels. The production scheme is that one car body Cb is added to two pairs of wheels 2W2 to make a complete car CbW4.
We know a car has four wheels, so the formula of CbW4 should seem logical. The approach in balancing chemistry equations uses the same logic. We need fire extinguisher fluid carbon tetrachloride The carbon "C" is like the car body. Chlorine always comes as a pair, so it's like the wheels that come in pairs.
To make carbon tetrachloride we need carbon and chlorine. We are 2 chlorine atoms short, so we show two pairs of chlorines.A decomposition reaction is the opposite of a synthesis reaction.
In decomposition, a In reactions in which one metal replaces another metal, the general equation is X + YB Write the balanced equation for the reactions that took place in this experiment. Write the word equation for each reaction.
