Write a balanced equation for the double-replacement neutralization reaction described, using the smallest possible integer coefficients. a reaction occurs when aqueous solutions of barium hydroxide and perchloric acid are combined.

The balanced chemical equation is given below.

Explanation:

Double-displacement reaction is defined as the reaction in which exchange of ions takes place. The general equation representing this reaction follows:

The balanced chemical equation for the reaction of barium hydroxide and perchloric acid follows:

By Stoichiometry of the reaction:

1 mole of barium hydroxide reacts with 2 moles of perchloric acid to produce 1 mole of barium chlorate and 2 moles of water molecule.

Hence, the balanced chemical equation is given above.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
