How many grams of NH3 are required to produce 4.65 g of HF

Chemistry

Answer:

1.32g

Explanation:

Given parameters:

Mass of HF   = 4.65g

Unknown:

Mass of NH₃ = ?

Solution:

We need to know the reaction equation first of all. The reaction that will produce HF involves;

                 2NH₃    +    5F₂    →    N₂F₄   + 6HF

Now that we know the reaction equation;

Find the number of moles of the HF;

        Number of moles  = \frac{mass}{molar mass}

         Molar mass of HF  = 1 + 19 = 20g/mol

        Number of moles  = \frac{4.65}{20}   = 0.23mole

From the balanced reaction equation;

        6 moles of HF is produced from 2 moles of NH₃  

        0.23 moles of HF will be produced from  \frac{0.23  x  2}{6}    = 0.08moles

Now we find the mass of NH₃

          Mass of NH₃ = number of moles x molar mass

                   Molar mass of NH₃  = 14 + 3(1) = 17g/mol

         Mass of NH₃   = 0.08 x 17  = 1.32g

SnCL2 is solid while SnCl4 is liquid ...?
Dmitrij [34]
<span>As the oxidation state of a metal increases, its electronegativity increases and the bonds become increasingly covalent. SnCl2 forms a network solid where the atoms are bonded to one another throughout a network of polar covalent bonds. SnCl4 is molecular, and held together by weaker intermolecular forces called London dispersion forces. </span>

What does X represent for this transmutation?
Dimas [21]

Answer:

 24He

Explanation:

When a nuclide is bombarded with alpha particles, we notice an increase in its mass and charge since an alpha particle has a mass of four and a charge of +2. recall that nuclear equations must be balanced. That is, the masses and charges on the left hand six and the right hand side of the nuclear reaction equation must be exactly the same.

Looking at the nuclear reaction at hand, the total mass on the left hand side has to be 246 while the total charge on the left hand side of the equation will be 98. Coming over to the right hand side, the total masses are also found to be the same as a neutron with no charge and a mass of 1 is produced. Hence the nuclear reaction equation is balanced when an alpha particle (helium nucleus) is substituted for X in the equation.

When Hg2+ concentration is 6.35x10^-4 M, the observed cell potential at 298K for an electrochemical cell with the following reac
JulsSmile [24]

Answer:

10.5 × 10^5 M

Explanation:

E°cell = E°cathode - E°anode

E°cell = 0.85 - (-0.74) = 1.59 V

From Nernst's equation;

Ecell = E°cell - 0.0592/n log Q

1.499 = 1.59 - 0.0592/6 log [Cr^3+]/6.35x10^-4

1.499 - 1.59 = - 0.0592/6 log [Cr^3+]/6.35x10^-4

-0.091 = -0.00987 log [Cr^3+]/6.35x10^-4

-0.091/ -0.00987 = log [Cr^3+]/6.35x10^-4

9.22 = log [Cr^3+]/6.35x10^-4

Antilog (9.22) = [Cr^3+]/6.35x10^-4

1.66 × 10^9 = [Cr^3+]/6.35x10^-4

[Cr^3+] = 1.66 × 10^9 × 6.35x10^-4

[Cr^3+] = 10.5 × 10^5 M
