Do chemical equations have no real structure?
Chemical equations provide the formulas of reactants and products in a chemical reaction. They usually do not provide structure unless supplemented with chemical structures.
Does a chemical reaction always require energy to start?
Yes, every chemical reaction requires activation energy, though in some cases the ambient heat of room temperature is enough to provide that energy.
WHAT In an exothermic reaction energy is transferred from?
In an exothermic reaction energy is transferred from the system to the surroundings. An exothermic reaction is a chemical or physical reaction that releases heat.
What does chemical reaction tell you?
A chemical equation is used in the means of writing out and describing a chemical reaction, such as the reactants and the substance that forms after the reaction (called the product)P.S: it took me a little to find out the question since i had it too. Some teachers decide to give out questions like these in attempt to get people to practice their research skills instead of just relying on a "magic book" for the answer.
What happens to a product during a chemical reaction?
The product doesn't exactly provide a role in a chemical reaction, but rather is the result of the chemical reaction occuring. The chemical reaction may occur specifically to produce that product to be used, and it then serves a role in that respect, but generally products don't play a role, but are just the outcome.

Chemical equations provide the formulas of reactants and products in a chemical reaction. They usually do not provide structure unless supplemented with chemical structures.
What info does a chemical equation provide?
A chemical equation shows a reaction between to chemicals using chemical formulas.
Why catalyst affect the rate of chemical reaction?
They provide alternative pathway for the reaction, usually with less energy barrier
Is skulls of human ancestors provide evidence of the anatomical changes that have occurred in hominids over time true?
Skull can provide an amazing amount of evidence of the anatomical changes that have occurred in hominids over time. Observations of the size of the skull can give us clues on how much the brain has evolved.
What is a dis charge?
A battery no longer able to provide a chemical reaction to create a charge
What chemical changes provide evidence that a compound has formed?
Signs of chemical reactions may be: - Gas release - Formation of a precipitate - Change of color - Change of odor - Change of pH - Change of aspect - Visible formation of new compounds - A violent reaction with explosion or fire - Bubbling
What is a dis charged battery?
A battery no longer able to provide a chemical reaction to create a charge
Does a chemical reaction always require energy to start?
Yes, every chemical reaction requires activation energy, though in some cases the ambient heat of room temperature is enough to provide that energy.
What information does the coefficient provide in a chemical reaction?
It tells you the number of molecules or number of moles of each substance.
WHAT In an exothermic reaction energy is transferred from?
In an exothermic reaction energy is transferred from the system to the surroundings. An exothermic reaction is a chemical or physical reaction that releases heat.

Methane gas is burned to provide heat. The chemical reaction for this process is shown in the equation below. CH4 plus 2O2 CO2 plus 2H2O plus energy What are the products in this chemical reaction?
CO2 + 2H2O + energy
