Answers
The answer is sublimation.
Sublimation is the chemical process whereby a solid turns into a gas without first becoming a liquid.
The word sublimation comes from the Latin word sublimare which means "raised to a higher status."
Examples of sublimation include surface layer of snow and ice turning into steam or fog without melting and dry ice which is the solid form of carbon dioxide which also undergoes sublimation.
The low temperature and sublimation makes dry ice an effective coolant or cooling agent . One of its main advantages is that it has a lower temperature than water ice and also does not leave any residue.

Answer: 1 . Unsaturated Solution
2. Saturated Solution
Explanation:
1 ..tedsaturauntionsolu----------- Unsaturated Solution
2. ratedsatulutisoon--------------Saturated Solution
An Unsaturated solution is defined as a solution which contains an amount of solute that dissolves completely since the amount of solute is still less than the maximum amount that can readily dissolve in such solution and an additional amount of solute if added continues to dissove in the solution. Here the solution is still less than the equilibrium point.
example include. Addition of salt or sugar in water and it dissoves completely.
A saturated solution is defined as A solution which contains a maximum amount of solute that an additional solute will no longer be capable of being dissolved further since its equilibrium point has been reached.
Example- The addition of sugar to water till it no longer dissolves
Carbonated water is a saturated solution saturated with carbon as can be seen in the air bubbles it gives offf in form of carbon.

Answer:
A) 2Na + = 2NaBr
Explanation:
As the problem says that you should find the balanced chemical equation for the synthesis of NaBr from Na and , the reactants are Na and
and the product is NaBr, so it can be writen as:
Na + = NaBr
Then you shoud balance the equation, it means that you should have the same number of each element in each part of the equation, so if you put a number 2 for the NaBr and the Na, the equation will be balanced:
2Na + = 2NaBr
