Answer:
Single displacement and reduction
Explanation:
In a single-displacement reaction, one element exchanges partners with another.
This is a single-displacement reaction, because the element Ca exchanges partners with H.
This is also a reduction/oxidation (redox) reaction, because the optically active of Ca increases from 0 to +2 (oxidation), while the oxidation number of H decreases from +1 to 0 (reduction),
The most common types of reactions are:
- Combination
- Decomposition
- Single displacement
- Double displacement
- Reduction/oxidation

In the modern periodic table, the elements are arranged according to their atomic number - not their relative atomic mass.
In the periodic table the elements are arranged into:
rows, called periods, in order of increasing atomic number
vertical columns, called groups, where the elements have similar properties
