Answer:

Here is the answer...

Explanation:

Option A is used to control sample that is known to be form.

The moles of silver (Ag) produced by 0.480 mol Mg has been 0.96 mol.

The balanced chemical equation has been given as:

[tex]\rm Mg\;+\;2\;AgNO_3\;\rightarrow\;Mg(NO_3)\;+\;2\;Ag[/tex]

The stoichiometric coefficient in the balanced chemical equation has been the representation of whole number ratio of moles of each reactant required to form the product.

From the given balanced equation, 1 mole  of Mg produces 2 mol of Ag. The moles of Ag produced from 0.480 mol Mg has been:

[tex]\rm 1\;mol\;Mg=2\;mol\;Ag\\0.480\;mol\;Mg=\;0.480\;\times\;2\;mol\;Ag\\0.480\;mol\;Mg=0.96\;mol\;Ag[/tex]

The moles of silver (Ag) produced by 0.480 mol Mg has been 0.96 mol.

Answer:

2.25 atm

Explanation:

Given data

Step 1: Convert the pressure of nitrogen to atm

We will use the relationship 1 atm = 101.325 kPa.

[tex]321kPa \times \frac{1atm}{101.325kPa} = 3.17 atm[/tex]

Step 2: Convert the pressure of oxygen to atm

We will use the relationship 1 atm = 14.6959 psi.

[tex]74.0psi \times \frac{1atm}{14.6959psi} =5.04atm[/tex]

Step 3: Calculate the partial pressure of hydrogen

The total pressure is the sum of the partial pressures.

P = pN₂ + pO₂ + pH₂

pH₂ = P - pN₂ - pO₂

pH₂ = 10.46 atm - 3.17 atm - 5.04 atm

pH₂ = 2.25 atm

Answer:

[tex]P_H=2.25atm[/tex]

Explanation:

Hello,

IN this case, we can apply the Dalton's law in order to understand the pressure behavior of a mixture as the summation of all the pressures of the compounds in the mixture, in this case, nitrogen, oxygen and hydrogen:

[tex]P_T=P_O+P_N+P_H[/tex]

So, since we are asked to compute the pressure of hydrogen, we simply solve for it:

[tex]P_H=P_T-P_O-P_N=10.46atm-74.0psi*\frac{1atm}{14.6959psi} -321kPa*\frac{1atm}{101.325kPa} \\\\P_H=2.25atm[/tex]

Laboratory acids are far too dangerous to taste, but you will have swallowed some dilute weak acids. Acids have a sour taste, like vinegar, which contains ethanoic acid, and lemons, which contain citric acid. These are safe to use in food, but they can still hurt if they get into a cut or into your eyes.

Explanation:

They can safely be consumed and do not irritate the skin. However, at greater concentrations weak acids can be harmful. Acids can react violently with water and are harmful in the presence of moisture in the mouth or eyes or in proximity with other aqueous solutions.

Answer:

[tex]V_{CO_2}=1.55x10^{5}LCO_2=155m^3CO_2[/tex]

Explanation:

Hello,

In this case, given the reaction:

[tex]2 C_8H_{18}(l) + 25 O_2(g)\rightarrow 16 CO_2(g) + 18 H_2O(g)[/tex]

The total consumed gallons are computed by considering 686 miles were driven and the consumption is 21.2 miles per gallon, thus:

[tex]V_{C_8H_{18}}=686miles*\frac{1gal}{21.2miles} =32.4gal[/tex]

Hence, with the given density, one could compute the consumed grams and consequently moles of gasoline as well as moles that were consumed:

[tex]n_{C_8H_{18}}=32.4gal*\frac{3785.41cm^3}{1gal} *\frac{0.805g}{1cm^3} *\frac{1mol}{114g}=864.95mol C_8H_{18}[/tex]

Next, since gasoline (molar mass = 114 is in a 2:16 molar relationship with the yielded carbon dioxide, we compute its produced moles as shown below:

[tex]n_{CO_2}=864.95mol C_8H_{18}*\frac{16molCO_2}{2molC_8H_{18}} =6919.6molCO_2[/tex]

Finally, we could assume the given STP conditions to compute the volume of carbon dioxide, as no more information regarding the space wherein the carbon dioxide is available:

[tex]V_{CO_2}=\frac{n_{CO_2}RT}{P} =\frac{6919.6mol*0.082\frac{atm*L}{mol*K}*(0+273)K}{1atm} \\\\V_{CO_2}=1.55x10^{5}LCO_2=155m^3CO_2[/tex]

Answer:

  665 kJ

Explanation:

We assume that carbohydrates and protein each have 4 kilocalories per gram, and that fat has 9 kilocalories per gram. Then the number of kilocalories in the peanut butter is ...

  4(6 +9) +9(11) = 159 . . . . kilocalories

Each kilocalorie translates to 4.184 kilojoules, so the total is ...

  (159 kCal)(4.184 kJ/kCal) = 665.256 kJ

2 Tbsp of crunchy peanut butter contains about 665 kJ of energy.

The number of kilojoules in two table spoons of crunchy peanut butter obtained by adding the amount of kilojoules in each food type is 673kJ

From the table given ; the amount of kilojoules per gram of each food type is :

I gram of Carbonhydrate = 17 kJ

6 grams of Carbonhydrate = (6 × 17) = 102 kJ

I gram of Fat = 38 kJ

11 grams of Carbonhydrate = (11 × 38) = 418 kJ

I gram of Protein = 17 kJ

9 grams of Carbonhydrate = (9 × 17) = 153 kJ

Therefore, the total kilojoules present is (102 + 408 + 153)kJ = 673 kJ

Answer:

In the given reaction "12 mol" of protons are consumed. The further explanation is given below.

Explanation:

Let's compose half of C₇H₈ on such controlled oxidation. For balance, firstly C is controlled, then O would be balanced that used H₂O after this H is balanced that used H⁺and after that change is balanced across each side through using e⁻ on the right.

The equation will be:

8H₂O+C₇H₈ ⇒ 3C₂H₃O₂⁻+CO₂+15H⁺+9e⁻ ...(equation 1)

⇒ e⁻+Fe(OH)₃ ⇒ Fe²⁺+3OH⁻

⇒ 3×(H⁺+OH⁻ ⇒ H₂O)

On adding both the above reactions, we get

⇒ e⁻+Fe(OH)₃+3H⁺ ⇒ Fe²⁺+3H₂O ...(equation 2)

Now,

On multiplying "9" into "equation 2" and adding it on "equation 1", we get

⇒ 8H₂O+C₇H₈+9e⁻+9Fe(OH)₃+27H⁺ ⇒ 9Fe²⁺+27H₂O+CO₂+15H⁺+9e⁻

On canceling the common terms from both sides of the reaction, we get

⇒ C₇H₈+9Fe(OH)₃+12H⁺ ⇒ 9Fe²⁺+19H₂O+CO₂ ...(equation 3)

The above "equation 3" seems to be the overall Redox reaction.

Throughout this reaction, 12 mol of a proton (H⁺) is absorbed. Because H+ is absorbed, pH would also increase.

Answer:

1. Galvanic oxidation. Example is the corrosion of aluminium wires when in contact with copper wires under wet conditions.

2. Rainwater or Damp/moist air

3. Chromium-plated steel screws or stainless steel screws or galvanized steel screws

Explanation:

1. Galvanic oxidation or corrosion occurs when two different metals with different electrode potentials are brought into contact with each other by means of an electrolyte (usually a aqueous solution), such that a redox reaction occurs leading to one metal with the more negative electrode potential (the anode) becoming oxidized, while the other less negative potential (the cathode) is reduced.

In order for galvanic corrosion to occur, three elements are required.

i. Two metals with different corrosion potentials (anode and cathode)

ii. Direct metal-to-metal electrical contact

iii. A conductive electrolyte solution (e.g. water) must connect the two metals on a regular basis.

For example oxidation (corrosion) of aluminium wires when in contact with copper wire under wet conditions.

2. The most likely electrolyte will be rainwater containing dissoved solutes (if the panel is in an exposed part of the house) or damp/moist air.

3. From the table, the most likely screw will be chromium-plated steel screws or stainless steel (made of iron and nickel) screws or galvanized steel (zinc-plated) screws.

All these possible screw components have a more negative electrode potential than copper. Thus they will serve as the anode in a galvanic oxidation with copper.
