Sodium combines with water to produce sodium hydroxide and hydrogen gas. which word equation represents this violent reaction?
sodium hydroxide + water mc002-1.jpg sodium + hydrogen
sodium + water mc002-2.jpg sodium hydroxide + hydrogen
sodium + hydrogen mc002-3.jpg sodium hydroxide + water
sodium + sodium hydroxide mc002-4.jpg water + hydrogen

sodium + water → sodium hydroxide + hydrogen

Explanation:

1) The first part of the statment "sodium combines with water" means that these two pure substances are the reactants.

Sodium is an alkali metal (group 1: Li, Na, K, Rb, Cs, Fr).

A typical chemical property of the alkali metal elments is that they react violently with water fo form the corresponding hydroxide and hydrogen gas.

2) The next two words, "to produce ". indicates, precisely, that what follow is the product of the reaction. In the chemical reaction it is indicated by the arrow →

3) Finally, you are told the products of the reaction: sodium hydroxide and hydrogen gas.

4) The word equation then follows the order reactants → products, which in this case is the sodium + water → sodium hydroxide + hydrogen

5) Using chemical symbols and conventions, that is:

Na(s) + H₂O (l) → NaOH(aq) + H₂(g).

sodium + water → sodium hydroxide + hydrogen
