If the temperatures were raised slowly under the same conditions, would ice made from fresh water or sea water melt first? Which would boil first? Which of these would allow the temperature of an ice cream maker to drop below 0°C? Which requires colder temperatures to freeze, unsalted roads or salted roads? Which requires more heat to boil, pure water or a sugar solution used for making candy?

1.sea water 2.fresh water 3. Salt and ice

4.salted roads 5. Sugar solution used for making candy

Explanation:

Because Truck

if the concentration of products is decreased, the equilibrium will shift toward the products). add an inert gas (one that is not involved in the reaction) to the constant-volume reaction mixture: this will increase the total pressure of the system, but will have no effect on the equilibrium condition.

explanation:

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.
