Use the following equation: delta G = delta H - T*deltaS. A reaction is spontaneous if delta G is negative.
A reaction will always be spontaneous (under any temperature) only if the change in enthalpy (delta H) is negative and the change in entropy (delta S) is positive.
If this is not the case, the reaction will only be spontaneous (negative delta G) for a range of temperatures (or could be always non-spontaneous)

What does this indicate about the reaction that took place in the beaker?
The formation of white precipitate indicates a chemical reaction occurred in the beaker that resulted in the precipitation of a solid product from the solution.
When CO2 mixes with limewater how do you know a chemical reaction took place?
When CO2 reacts with limewater (calcium hydroxide), the solution turns milky due to the formation of calcium carbonate, which is insoluble and precipitates out. This indicates a chemical reaction has taken place as a new substance with different properties has formed.

What is a product of a reactant?
A product is a substance formed after a chemical reaction from the reactants involved in the process. It is the result of the reaction and can be a single compound or a mixture of compounds that were not present before the reaction took place.
Is dissolving salt in water a physical or chemical change?
Dissolving salt in water is a physical change- no chemical reaction took place. If the water evaporates, the salt is still there.

What is the evidence that a chemical reaction took place when zinc mixed with HCl?
Evidence that a chemical reaction took place when zinc mixed with HCl includes the production of hydrogen gas bubbles, formation of zinc chloride as a product, and an increase in temperature of the reaction mixture due to the exothermic nature of the reaction. Additionally, the disappearance of the solid zinc as it undergoes dissolution is another indication that a chemical reaction has occurred.
How do you know that a chemical change took place when sodium and clorine join to form table salt?
it is an ionic and exothermic reaction i.e. when it will take place heat will be liberated
How do you determine the statute of limitations if you have moved?
That depends on many circumstances. Typically the laws of the place the event took place are key. But, leaving the state often tolls that limit.

Does a chemical reation produce new substances?
"New substances" is a vague description of what happens in a chemical reaction. Simply put though, yes. An example of this would be if you took baking powder and vinegar and mixed them together, the resulting chemical reaction would create Carbon Dioxide. That is a new substance, it wasn't there until the reaction took place.
