Write out the balanced equation for the reaction that occurs when Li and H2O react together. You do not need to make your subscripts smaller; just write them out at regular numbers. For example: H2O.

Based on reactivity, which of the following elements can replace aluminum (Al) in a compound during a single replacement reaction?

B
Ca
Zn
Fe

Which of the following pairs of reactants will react together to produce water (H2O) as one of the products?

NaOH and H3PO4
MgO and Ca(OH)2
HBr and NaNO3O
CaO and H2O

mathmate · Answer

Hints: (1) the products are LiOH and hydrogen. Try to write the balanced equation. (2) use the electrochemical series, see, for example: http://www.chemguide.co.uk/physical/redoxeqia/ecs.html (3) It takes an acid and an alkali to produce water through a reaction called neutralization.
