How does a chemical equation show that a chemical reaction has occurred?

∙ 8y ago
A chemical equation shows that chemical reaction has occurred as new substances have been formed from the reagents. A chemical equation has two sides before reaction and after reaction, if there is any change from the before reaction side to the after reaction side, it indicates that a chemical reaction has just occurred.

What information does the complete ionic equation gives?
It lists only the substances that are changed.
What is the only way to confirm that a chemical change has taken place?
To be certain that a chemical change has taken place you check the composition of the sample before and after the change. The following is a chemical property of water at 4 C is its ability to decompose into hydrogen and oxygen.
How do you balance chemical formulas?
Format Method - Writing the symbol of the cation and then the anion. Add whatever subscripts in order to balance the charges. Crisscross Method - The numerical value of the charge of each ion is crossed over and becomes the subscripts for the other ion.
When infrared images show that an area is getting hotter what is probably happening there?
Without knowing the context of this question there could be a number of reasons. There could be an exothermic chemical reaction such as a fire. The area could be heated by the sun. Moving parts in a machine may be experiencing friction. If it is on or near a volcano it is a sign that magma is getting closer to the surface.
How do fireworks show chemical reactions?
The brilliant colors you see when the fireworks explodes comes from a wide variety of metal salts that are packed inside the firework. Now, when most people think of salt they're thinking of the white crystals they sprinkle on their food. That is a salt, but it's not the only salt. That's sodium chloride (NaCl). A salt is any metal atom bound to a non-metal atom. In the case of table salt, sodium is the metal and cholrine is the non-metal. When these salts burn they absorb energy, exciting electrons in the atoms. The excited electrons jump up to a higher energy level, but they are very unstable in that higher energy state. When the electrons relax back to their low energy state they release a photon of light. The color of light changes depending on the metal salt that is used. So, for example, strontium salts burn red, calcium shines orange, green is from barium, white is from magnesium, and copper shines a beautiful blue. Combinations of these salts yields the combinations of their colors (strontium and copper shines purple).

What is a special type of sentence that show what happens during a chemical reaction?
a word equation, or a chemical equation
Does a chemical equation show the number of atoms lost during a chemical reaction?
no
A representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products.?
This representation is a chemical equation.
Is this question true or false chemical reaction show is it represented in the chemical equation for the reaction?
sandy hit the bed
What are the arrows of a chemical equation read as?
These arrows show the sense of a reaction.
What is the statement that uses chemical formulas to show the identities and relative amounts involved in a chemical reaction?
Chemical Equation
How would you write the equation to show water evaporation?
Evaporation is not a chemical reaction.
What a short easy way to show a chemical reaction using symbols?
Writing a chemical reaction with symbols: Ex.: NaCl + AgNO3 = AgCl (s) + NaNO3 A mathematical (digital) system for the writing of chemical equations exist but it is rarely used.
What is a shorthand way of writing a chemical reaction?
A chemical reaction is always written with the reactants (the things you mix together to do the reaction) on the left and the products (the stuff you get) on the right. In between is an arrow pointing right to indicate that the reactants react and become the products. Catalysts are sometimes listed above the arrow. And don't forget to balance the equation.
What number of products and reactants are produced by a chemical reaction?
It depends on the reaction. Also, only the products are produced by a chemical reaction; the reactants produce the reaction and are changed in the reaction to the products. (If you have a chemical equation, the number of distinct molecules and/or isolated element symbols on the right side of the equation will show how many distinct products are formed in the reaction.)
