It would be a synthesis reaction
Answer:
The correct option is The net ionic equation shows the spectator ions in the reaction.
Explanation:
The net ionic reaction will show us the ions which are involved in the reaction. It also helps us the charges present on each atom and how a reaction occurs due to these charges on atoms. It shows us that which ions actually take part in a chemical reaction and which ions do not take part in the reaction and are involved only for balancing the equation.
Answer: e. Two of these
Explanation:
(a) 
When
is dissolved in water. It reacts to form sulfurous acid. The chemical reaction is shown below:

Therefore,
is acidic when dissolved in water.
(b)
When
is dissolved in water. It reacts to form nitric acid. The chemical reaction is shown below:
Therefore,
is acidic when dissolved in water.
(c)
Sodium is a metal. It gives sodium hydroxide on reaction with water. The chemical reaction is as follows:

Therefore, Na is basic when dissolved in water.
(d) 
Calcium oxide is a metallic salt. It gives calcium hydroxide on reaction with water. The chemical reaction is as follows:
,
Therefore,
is basic when dissolved in water.
(e) Two of these.
Since both
and
give acids when dissolved in water, both are acidic.
Answer:
KOH is a strong base, and therefore dissociates completely into negative and positive ions in water solution. pH 8.35 is a high pH (> 7), therefore this is a basic solution. 4.
Explanation:
Answer:
Different compounds are formed.
Explanation:
Due to this switching of chemicals, the result of both beakers will be different because the chemicals react with the different solution in the beaker. The composition of both chemicals are different from one another which produces different compounds or products when they are mixed with the solution so we can say that this switching of chemicals will definitely affect the results of the experiment. The student will observe the formation of different compounds and different colour of the solution.
