The production of water proceeds according to the following equation.
2h2(g) + o2(g) → 2h2o(g)
which describes a way to speed up the collisions between hydrogen and oxygen molecules to produce more water?
a. use a less-intense source of heat on the reactants.
b. maintain the same temperature of the reactants.
c. place the reactants in a smaller container.
d. reduce the concentration of the reactants.

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.

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong
