How many Faradays of electricity are carried by 1.505×10^23 electronsk​
aksik [14]

Mole of electron required by 1.505 *10^{23} mole is 2.5* 10  ^{-1}

  • Faraday law expressed how the  change that is been being produced by a current at an electrode-electrolyte interface is related and  proportional to the quantity of electricity  that is been used.

  • There is one mole of electron required for 1 Faraday of electricity.

  • Avogadro constant is 6.02*10^{23}

  • Mole of electron can be calculated by dividing the number of electron by avogadro's constant.

=\frac{1.505*10^{23} }{6.02*10^{23} }

= 2.5* 10^{-1}  Faraday  of electricity

Therefore, it requires  2.5*10^{-1} Faraday of electricity for the 1.505 *  10^{23}  mole.

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

What is the pH of a 6.7 x 10^−5 M H+ solution?
lyudmila [28]

Answer:

pH = 4.17

Explanation:

According to the molar concentration you stated, pH of the solution is: 4.17

Remember that pH = - log [H⁺]

and [H⁺] = 10^-pH

When:

pH > 7 →  Basic solution

pH = 7 → Neutral solution

pH < 7 → Acid solution
