Answer : The net ionic equation will be:
Explanation :
Complete ionic equation : In complete ionic equation, all the substance that are strong electrolyte and present in an aqueous are represented in the form of ions.
Net ionic equation : In the net ionic equations, we are not include the spectator ions in the equations.
Spectator ions : The ions present on reactant and product side which do not participate in a reactions. The same ions present on both the sides.
The balanced molecular equation will be,
The complete ionic equation in separated aqueous solution will be,
In this equation the species, 
are the spectator ions.
By removing the spectator ions , we get the net ionic equation.
The net ionic equation will be:
There are four processes in water cycle. Starting from the heat from the sun is the process of evaporation.
Evaporation: In this process, light from the sun evaporate water from oceans, rivers, lakes, ice and soil into water vapor. Water vapor molecules combine to form clouds.
Condensation: In this process, water vapor from clouds cool down and turns back into liquid water in the form of water droplets. These water droplets stays in the air. Precipitation: In this process, water droplets they combine in the air, they become too heavy to stay in the air. Therefore, they fall in the form of rain, snow or other form.
Collection: In this process, water that falls as rain, snow or other form comes back in the ocean, lakes, river or any other water body. Water will also be absorbed by soil and will be collected as ground water.

Answer: The purpose of a hypothesis is to find the answer to a question.
Explanation:
A hypothesis is a statement which is written as a source of prediction which is based upon the assumption of the cause of a natural event or process. The purpose of the hypothesis is basically to find the relevant answers to the scientific question. It is based upon few evidences and the entire statement of the hypothesis is tested using experimental procedures.
The answer for the following question is mentioned below.
+3 
→2 
+2 
the equation is balanced.
Explanation:
The steps required to balance a chemical equation is:
Firstly,write the formula of the compound/substance.
Secondly,count the number of atoms in each element on each side of the equation
Thirdly,Adjust the co-efficient.Balance the atoms or the ions present in the greatest number.
You may do this by finding the lowest common multiple of two.
Continue systematically to balance the atoms or ions on the rest of the side (i.e.)on the other side.
Lastly,check the number of atoms each elements is same on both the sides
From the equation:
Before balancing the equation:
+ → +
After balancing the equation:
+3 →2 +2
Therefore the given equation is balanced.
Solution :
An 
reaction is a type of 
in organic chemistry where the enol or an enolate ion reacts with the carbonyl compound and forms a 
-hydroxyaldehyde or a -hydroxyketone, and then followed by a dehydration to give conjugated enone.
Benzaldehyde reacts with methylketone and forms two products:
