N2+3H2=>>2NH3. If 6.72dm³ of each of Nitrogen and hydrogen (measured at S. T.P.) are made to produced Ammonium. Which of the reacted will be in excess and by how many moles?

Hydrogen, 0,2 mol

Explanation:

= 22, 4 l/mol

V () = 6,72 = 6,72 l

V () = 6,72 = 6,72 l

The formula is:

n =

n  () = 6,72l /22,4 l/mol = 0,3 mol

n  () = 6,72l /22,4 l/mol = 0,3 mol (the same)

But from the equation we get a proportion that 1 mol  () - 3 mol ()

(we have more hydrogen than is need for the reaction)

So there is excess of

We only need   = 0,1 mol ()

0,3 mol (hydrogen quantity we have) - 0,1 mol (hydrogen quantity we need for the reaction) = 0,2 mol (excess)

make me the brainliest

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.
