Is a rusty penny an example of a chemical reaction true or false?
Yes. The rust on the penny indicates that a reaction between the penny and its environment has occurred. Since a new material was formed from this reaction (the rust) the reaction must be a chemical reaction.
A combination reaction occurs when one reactant forms two or more products.?
The correct answer in apex is TRUE!
A combination reaction occurs when a substance usually containing carbon reacts with oxygen to produce energy in the form of heat and light true or false?
FALSE. I would call this reaction a combustion reaction. I always understood a combination reaction to be a reaction between two elements or compounds to form 1 product. For example, sodium reacting with chlorine to produce sodium chloride. A combustion reaction usually forms more than one product. When burning fossil fuels (coal, gas, oil, etc.) the fuel contains compunds which are composed of mostly carbon & hydrogen. So when reacted with oxygen (or combusted) the products are carbon dioxide & water vapor, in addition to the heat & light produced.
Mass can be lost or gained in a chemical reaction.?
False
A double-displacement reaction occurs when the negatively charged metal of one compound replaces the positively charged gas of another compound to form two new compounds during a chemical reaction?

Mixing baking soda with vinegar is an example of an oxidation-reduction reaction. true or false?

Is fusion a type of chemical reaction?
False
Does the center of the reaction in the dark reaction split the water?
False
If you have a forward reaction to a reverse reaction what equilibrium is that?
true or false
True or false An oxidation-reduction reaction occurs when electrons are transferred from one substance to another in a chemical reaction?
false
A chemical reaction causes a chemical change true or false?
It is true that a chemical reaction causes a chemical change. An example of this can be seen by adding baking soda to vinegar.
A double-displacement reaction occurs when the negatively charged metal of one compound replaces the positively charged gas of another compound to form two new compounds during a chemical reaction?

A single displacement reaction is always a redox reaction but a redox reaction isnt always a single displacement reaction?
false true
