pishuonlain [190]

Answer:

[Na₂CO₃] = 0.094M

Explanation:

Based on the reaction:

HCO₃⁻(aq) + H₂O(l) ↔ CO₃²⁻(aq) + H₃O⁺(aq)

It is possible to find pH using Henderson-Hasselbalch formula:

pH = pka + log₁₀ [A⁻] / [HA]

Where [A⁻] is concentration of conjugate base,  [CO₃²⁻] = [Na₂CO₃] and  [HA] is concentration of weak acid, [NaHCO₃] = 0.20M.

pH is desire pH and pKa (<em>10.00</em>) is -log pka = -log 4.7x10⁻¹¹ = <em>10.33</em>

<em />

Replacing these values:

10.00 = 10.33 + log₁₀ [Na₂CO₃] / [0.20]

<em> [Na₂CO₃] = 0.094M</em>

<em />

Calculate the ph of the resulting solution if 34.0 ml of 0.340 m hcl(aq is added to
anyanavicka [17]
According to the reaction equation:

HCl(aq) + NaOH(aq) →  NaCl(aq) +  H2O(l)

a) Part 1):

first, we need to get moles HCl = molarity * volume

                                                      = 0.34m * 0.034

                                                      = 0.01156 mol

then, we need moles of NaOH = molarity * volume

                                                    =  0.34 * 0.039

                                                     = 0.01326 mol

when NaOH excess:

∴ NaOH remaining = 0.01326 - 0.01156

                                 = 0.0017 mol 

when the total volume = 0.039 + 0.034

                                       =  0.073 L

∴[OH] = moles / total volume 

           = 0.0017mol / 0.073 L

           =  0.0233 M

∴ POH = -㏒[OH-]

             = -㏒0.0233

             = 1.63 

∴ PH = 14- 1.63

         = 12.37 

b) part 2:

as we got moles HCl = molarity * volume 

                                   = 0.34 * 0.034

                                  = 0.01156 mol 

then moles NaOH = molarity * volume 

                               = 0.39 * 0.044

                               = 0.01716 mol

NaOH remaining = 0.01716 - 0.01156

                             = 0.0056 mol

when the total volume = 0.034 + 0.044

                                       = 0.078 L
∴[OH-] = 0.0056 / 0.078

            = 0.0718 M

∴ POH = -㏒[OH-]

            = -㏒0.0718

            = 1.14

∴PH = 14 - POH

        = 14 -POH

       = 14 - 1.14

       = 12.86

determine the pressure in kpa of hydrogen gas produced when 29.51g of aluminum reacts with excess sodium hydroxide and water if
Mashcka [7]

The pressure of hydrogen gas is 276.25 Kpa .

Given,

Mass of aluminum = 29.51g

Temperature (T) = 25.67 degC =298.67 K

Volume (V) = 14.75 L

The required equation when aluminum reacts with excess sodium hydroxide and water is given by ,

2Al + 2NaOH + 2H2O ==>2NaAlO2 + 3H2

molecular mass of aluminum =26.98 g

1 mole of aluminum= 26.98g

2 moles of aluminum = 53.96g

2 mole of aluminum produces =  3  moles of hydrogen gas

53.96 g of aluminum produces = 6 g of hydrogen gas

29.51 g of aluminum produces = 6*(29.51) /53.96 =3.28 g of hydrogen gas

Thus ,

2 g of hydrogen gas = 1 mole of hydrogen

3.28 g of hydrogen gas = 3.28/2 mole =1.64 mol of hydrogen

Thus , n = 1.64 mol

According to ideal gas equation ,

PV=nRT

P=nRT/V

P = 1.64 * (0.0821L atm K^-1mol^-1 ) *(298.67 K)/14.75L

P=2.726 atm

P= 276.25 Kpa

Hence the pressure of hydrogen gas is 276.25 Kpa .
