Milk of magnesia is often taken to reduce the discomfort associated with acid stomach or heartburn. The recommended dose is 1 te
Igoryamba

Answer:

8.61 mL of the HCl solution

Explanation:

The reaction that takes place is:

  • 2HCl + Mg(OH)₂ → MgCl₂ + 2H₂O

From the given mass of Mg(OH)₂, we can calculate <u>the moles of HCl that are neutralized</u>:

  • 4x10² mg = 400 mg = 0.400g
  • 0.400g Mg(OH)₂ ÷ 58.32g/1mol = 6.859*10⁻³ mol Mg(OH)₂
  • 6.859*10⁻³ mol Mg(OH)₂ * \frac{1molHCl}{1molMg(OH)_{2}} = 3.429x10⁻³ mol HCl

Finally, to calculate the volume of an HCl solution, we need both the moles and the concentration. We can <u>calculate the concentration using the pH value</u>:

  • pH = -log[H⁺]
  • 1.4 =  -log[H⁺]
  • 10^{-1.4} = [H⁺]
  • 0.0398 M = [H⁺] = [HCl]  *Because HCl is a strong acid*

Thus, the volume is:

  • 0.0398 M = 3.429x10⁻³mol HCl / Volume
  • Volume = 8.616x10⁻³ L = 8.62 mL

Is the electrochemical cell spontaneous or not spontaneous as written at 25 ∘C ? spontaneous not spontaneous Calculate the poten
givi [52]

Answer:

The cell potential is 0.609 V. Given E > 0 the electrochemical cell is spontaneous as written.

Explanation:

Let's consider the oxidation and reduction half-reactions and the global reaction.

Anode (oxidation): Sn²⁺(0.0023 M) ⇒ Sn⁴⁺(0.13 M) + 2 e⁻

Cathode (reduction): 2 Fe³⁺(0.11 M) + 2 e⁻ ⇒ 2 Fe²⁺(0.0037 M)

Global reaction: Sn²⁺(0.0023 M) + 2 Fe³⁺(0.11 M) ⇒ Sn⁴⁺(0.13 M) + 2 Fe²⁺(0.0037 M)

The standard cell potential (E°) is the difference between the standard reduction potential of the cathode and the standard reduction potential of the anode.

E° = E°red,cat - E°red,an

E° = 0.771 V - 0.154 V = 0.617 V

The Nernst equation allows us to calculate the cell potential (E) under the given conditions.

E=E\° -\frac{0.05916}{n} logQ\\E=E\° -\frac{0.05916}{n} log\frac{[Sn^{+4}].[Fe^{2+}]}{[Sn^{2+}].[Fe^{3+} ]} \\E=0.617V-\frac{0.05916}{2} log\frac{(0.13).(0.0037)}{(0.0023).(0.11)} \\E=0.609V

The cell potential is 0.609 V. Given E > 0 the electrochemical cell is spontaneous as written.

A throat lozenge contains 5.0 mg of menthol, which has the formula c10h20o.
Pachacha [2.7K]
A) 
the molecular formula of menthol is C₁₀H₂₀O 
molar mass of menthol is (12x10) + (1x20) + 16 = 156 g/mol
number of moles of menthol in 156 g - 1 mol
In 1 g of menthol number of moles - 1/156 
Therefore in 5.0 g of menthol - 1/156 x 5 = 0.032 mol
therefore in 5.0 g of menthol there are 0.032 mol of menthol

b)
Molar mass of menthol - 156 g/mol
1 mol of menthol weighs 156 g
Therefore 1.56 mol of menthol weighs - 156 g/mol x 1.56 mol = 243.36 g

True or False? Chemical manufacturers strive to produce herbicides
julsineya [31]

Answer:

True.

Explanation:

Chemical manufacturers strive to produce herbicides and insecticides that get rid of all pests, beneficial or not because pests and weeds reduces both quality and quantity of the crops which directly affects country's economic conditions. There are several countries which are agricultural based means they depend on the agricultural goods. So for producing maximum yield of crops, they use pesticides and herbicide to make the crop free from the pest and weeds. So chemical manufacturers produce chemicals for pest and weeds.
