Ammonia (NH3) can be synthesized from nitrogen gas (N2) and hydrogen gas (H2) by the following reaction.
Advocard [28]

Answer:

                      %age Yield  =  66.05 %

Explanation:

                     In order to check the efficiency of a reaction the %age is calculated so that it can be concluded that either the conditions provided for certain reactions are favourable or not because at large scales reactions with greater %age yields are favoured as it results in high product quantity and hence, greater economical advantages.

                   The percent yield is given as;

                  %age Yield  =  Actual Yield / Theoretical Yield × 100

Putting values,

                   %age Yield  =  253 g / 383 g × 100

                   %age Yield  =  66.05 %

Hence, for the given reaction the success of the reaction is only 65% hence, steps can be made to improve this yield by modifying the reaction conditions.

Tube worms that survive near geothermal vents of hydrogen sulfide rely on bacteria living inside them to obtain energy by the ox
mars1129 [50]

Answer:

The overall change in the oxidation number of sulfur is 8.

Explanation:

Oxidation number is defined number assigned to an element in reaction which represent the loss or gain of electrons by an atom of an element in a compound.

In H_2S

let the oxidation number of S in hydrogen sulfide be x.

(+1\times 2)+x=0

x = -2

In SO_4^{2-}

let the oxidation number of S in sulfate ion be x.

x+(-2\times 4)=-2

x = -2 + 8 = +6

The overall change in the oxidation number of sulfur :

= [+6] - [-2] = 8

S^{-2}\rightarrow S^{+6}+8e^-

What kind of chemical bond is formed between nonmetals? Explain your answer
Harman [31]

Answer:

covalent bond

Explanation:

Between atoms of non-metals covalent bond is formed. Atoms of non-metals have close values of electronegativities, so electrons, that are forming bond, shared between atoms, and may be just a little moved to the side of non-metal that have more electronegativity.
