Ammonia is produced synthetically by the reaction: 2Fe+3Cl2 --- 2FeCl3

Chemistry
1 answer:
AlladinOne [14]3 years ago
5 0

Ammonia is synthetically by reaction

N2 +3H2 ---> 2NH3


(a) The process is exothermic. This is because heat is released during the formation of NH3(ammonia)


(b) The moles of NH3 formed when 1 mole of N2 reacted with hydrogen is 2 moles

by use of mole ratio between N2 to NH3 wich is 1:2 the moles of NH3 is therefor = 1 x 2/1 = 2 moles


(c) The moles of NH3 produced if 18 x10^23 molecules of H2 reacted is 1.993 moles of NH3


calculation

by use of Avogadro law constant calculate the moles of H2 reacted


1 mole = 6.02 x 10^23 molecules

? = 18 x10 ^23 molecules


by cross multiplication

= 1 mole x 18 x10 ^23 / 6.02 x10^23 = 2.99moles of H2

by use of mole ratio of H2 : NH3 which is 3:2 the moles of NH3 is therefore= 2.99 x/3=1.993 moles

How do the terms denature, catalyst, active site, and substrate relate to each other
postnew [5]

Explanation:

The enzyme 's active site binds to the substrate. Increasing the temperature generally increases the rate of a reaction, but dramatic changes in temperature and pH can denature an enzyme, thereby abolishing its action as a catalyst. ... When an enzyme binds its substrate it forms an enzyme-substrate complex.

A compound is found to contain 50. 05% sulfur and 49. 95% oxygen by mass. What is the empirical formula for this compound? SO S2
jekas [21]

The empirical formula for the given compound has been \rm SO_2. Thus, option C is correct.

The empirical formula has been the whole unit ratio of the elements in the formula unit.

<h3>Computation for the Empirical formula</h3>

The given mass of Sulfur has been, 50.05 g

The given mass of oxygen has been 49.95 g.

The moles of elements in the sample has been given by:

\rm Moles=\dfrac{Mass}{Molar\;mass}

  • Moles of Sulfur:

\rm Moles\;S=\dfrac{50.05}{32}\\&#10; Moles\;S=1.56\;mol

The moles of sulfur in the unit has been 1.56 mol.

  • Moles of Oxygen:

\rm Moles\;O=\dfrac{49.95}{16} \\&#10;Moles\;O=3.12\;mol

The moles of oxygen in the unit has been 3.12 mol.

The empirical formula unit has been given as:

\rm S_{1.56}O_{3.12}=SO_2

Thus, the empirical formula for the given compound has been \rm SO_2. Thus, option C is correct.
