Identify ALL the possible mol ratio from this balanced equation:

Chemistry
1 answer:
grandymaker [24]3 years ago
3 0

Answer:

\frac{1 mole of N_{2} }{3 moles of H_{2} }

Explanation:

The equation of the reaction:

   Nitrogen gas N₂ reacts with Hydrogen as H₂ to produce ammonia NH₃;

 

          N₂    +    H₂    →    NH₃  

 The balanced equation is ;

        N₂    +    3H₂    →    2NH₃  

The mole ratio is the ratio of the coefficients of the combining reactants;

   1 mole of N₂ combines with 3 mole of H₂;

So;

      \frac{1 mole of N_{2} }{3 moles of H_{2} }

An atom with 2 protons 3 neutrons and 2 electrons has a charge of
V125BC [204]

Answer: It has a charge of -2 because it has 2 more electrons than protons meaning it has a negative charge of 2 which is -2. Neutrons don't effect charge.

( +1 +1 -1 -1 -1 -1) = -2

Each proton has a charge of +1 and each electron has -1.

2(1) - 4(1) = -2

Two solutions are created by mixing one solution containing lithium nitrate with one containing sodium phosphate.
babunello [35]

Answer:

Solution A that will form a precipitate with Ksp = 2.3 x 10−4

Explanation:

                                  Li₃PO₄ ⇄ 3 Li⁺(aq) + PO₄³⁻(aq)

                                                     3S               S

Where S = Solubility(mole/lit) and Ksp = Solubility product

⇒ Ksp = (3S)³ x (S)

⇒ 27S⁴ = 2.3x10−4

⇒ S = 0.05 mol/lit

Concentration of Li₃PO₄ precipitate = 0.05

<u>Solution A </u>

0.500 lit of a 0.3 molar LiNO₃ contains 0.5 x 0.3 = 0.15 mole

0.4 lit of a 0.2 molar Na₃PO₄ contains = 3 x 0.4 x 0.2 = 0.24 mole

                                     3 LiNO₃ + Na₃PO₄ → 3 NaNO₃ + Li₃PO₄

(Mole/Stoichiometry)    \frac{0.15}{3}                \frac{0.24}{1}

                                   = 0.05            = 0.24

Since from (Mole/Stoichiometry) ratio we can conclude that LiNO₃ is limiting reagent.

So concentration of Li₃PO₄ is equal to 0.05.

g If attempting to dissolve both silver bromide and silver chloride in aqueous solution through complex ion formation, which dat
ziro4ka [17]

Answer:

Kf

Explanation:

The stability constant Kf of a given complex specie is an equilibrium constant that represents the formation of that particular complex specie in solution. It measures the strength of the interaction between the ligands and metal that form the particular complex specie. The magnitude of Kf shows how easily a complex specie is formed in solution.

Hence if I want to dissolve the bromides or chlorides of silver which are ordinarily insoluble in water by means of complex formation, the magnitude of the stability constant for each particular complex specie is important as it gives information regarding the thermodynamic feasibility of the process.
