Answer:
The correct answer is : No, because there are 4 hydrogen atoms on the reactants side and 2 on the products side.
Explanation:

The given reaction equation is not balanced because:
- Number of hydrogen atoms  on both sides are not equal that is 4 on reactants side and 2 on products side.
 - Number of oxygen atoms on both sides are not equal that is 3 on reactants side and 2 on products side.
 
In a balanced chemical equation number of atoms of each elements are equal on both sides.
So, the balanced chemical equation will be:

 
        
             
        
        
        
Answer:
Methods for determining or delivering precise volumes include volumetric pipets and pycnometers; less precise methods include burets, graduated cylinders, and graduated pipets. In this experiment, you will measure masses and volumes to determine density. Four different metal cylinders are investigated.

Ionic compounds are those compounds which form an ion or
dissociates into ions when placed in a solution. These compounds are made up of
a metal and non metal. From the choices, here are the ionic compounds:
