Explanation:

Flourine has atomic number of 9 and hence 9 electrons in its neutral state. The full electronic configuration is given as;

1s2 2s2 2p5

Carbon has atomic number of 6 and hence 6 electrons in it's neutral state. The noble gas notation as the following format;

[closest noble gas before the element] remaining electrons

What reaction is depicted by the given equation: au3 3e− au
mrs_skeptik [129]
This is a reduction half-reaction. Initially, gold exists as Au^{3+}, and after the reaction, it has been converted to elemental gold. To make this possible, three electrons must be added to <span>Au^{3+}. This fits within the definition of reduction reactions, where the reactant gains electrons in the reaction.</span>

How many grams of h2 are needed to produce 14.51 g of nh3?
gavmur [86]

Answer:

               2.57 g of H₂

Solution:

The Balance Chemical Equation is as follow,

                                          N₂  +  3 H₂    →    2 NH₃

According to Balance equation,

         34.06 g (2 moles) NH₃ is produced by  =  6.04 g (3 moles) of H₂

So,

               14.51 g of NH₃ will be produced by  =  X g of H₂

Solving for X,

                      X  =  (14.51 g × 6.04 g) ÷ 34.06 g

                     X =  2.57 g of H₂
