In the reaction of nitrogen with hydrogen to produce ammonia, NH3, how many moles of ammonia would be produced from 1.0 mol of hydrogen and excess nitrogen? N2 + 3 H2 --> 2 NH3

0.33 mol
0.67 mol
2.0 mol
1.3 mol

0.67 mol

Explanation:

Given data:

Number of moles of ammonia produced = ?

Number of moles of hydrogen = 1.0 mol

Amount of nitrogen = excess

Solution:

Chemical equation:

N₂ + 3H₂   →       2NH₃

Now we will compare the moles of ammonia with hydrogen.

                       H₂            :           NH₃

                         3             :            2

                       1.0             :        2/3×1.0 = 0.67

Thus, from 1.0 mole of hydrogen 0.67 moles of ammonia will produced.

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
