How can you tell that a chemical reaction occurred from the copper sulfate?
You have to notice what happens during the reaction and what products have been obtained.
How do chemical reaction change substances?
After a chemical reaction, some of the bonds have been broken, and some new bonds have been formed. So, that's how a substance is changed after the reaction.
What goes into a reaction and what comes out of a reaction?
Reactantd go into a reaction and the products come out of a reaction. For want of a better expression the atoms in the reactants play 'musical chairs' to form the products. e.g. Hydrochloric Acid and potassium hydroxide are the reactants and potassium chloride and water are the products. HCl(aq) + KOH(aq) = KCl(aq) + H2O(l) Notice how the atoms all move place.
Would there be a reaction if you add acid to a rock that had been near a igneous rock?
Not unless there is calcite in it.
Which reaction makes ADP light or dark?
It is the light reaction. Then they moves to dark reaction

In an exothermic reaction is the energy of the products higher or lower than that of the reactants?
In an exothermic reaction the energy of the products is less than that of the reactants.

What observations would you make when checking a delivery?
Make sure it's in date and nothing been opened or bumbled
What type of reaction is H2O plus CO2?
It is synthesis since your adding them together other wise decomposition is breaking them apart
What does it mean to say a reaction proceeds to 10 percent completion?
It means 10% of reactants have been converted into products and 90% are still there as reactants.
Has francium ever been tested with water?
Francium would react with water by this equation: 2Fr + 2H2O -->2FrOH + H2 The products here are francium hydroxide and hydrogen gas. However, it would be impossible to gather enough francium to demonstrate this reaction.
The law of what and mass applies to chemical reactions?
The law of conservation of matter/mass applies to chemical reactions. This is why chemical equations must be balanced. The matter that goes into a chemical reaction is present in the products of the reaction, but the atoms have been rearranged to form products with new and unique properties different from the reactants.
What is catailysis?
It is an enzyme that allows for a reaction to accur sooner then normal. The catalysis makes the activation energy needed by the reaction less then what would have been normally. Allowing for a reaction to happen faster.
Why have scientist change their ideas on the model of the Atom?
There has been more and more observations about the atom that has changed it since then. They revised it to explain the observations.
Is an explanation of observations that have been tested many times?
A theory
