Answer:

Single displacement and reduction

Explanation:

In a single-displacement reaction, one element exchanges partners with another.

\rm Ca + 2H$_2$O $\longrightarrow$ Ca(OH)$_2$ + H$_2$

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

How many moles of water are needed to react with 2.2 moles of li2o? given: li2o + h2o â 2 lioh?
Debora [2.8K]
Examining the given reaction:
Li2O + H2O ........> 2LiOH
we find that, 1 mole of Li2O is required to react with one mole of H2O in order to produce two moles of LiOH.

Therefore, the ration between the required Li2O and H2O is 1:1
Based on this, 2.2 moles of H2O (water) are required to react with 2.2 moles of Li2O
