The theoretical yield of NH3 is 945 grams. You conducted the experiment and only produced 598 grams.

Answers

Answer:

Given theoretical yield of NH3 is 945g.

The actual yield is 598g.

What is the %yield?

Explanation:

%yield of a chemical reaction can be calculated by using the formula:

[tex]%yield=\frac{actual yield}{theoretical yield} * 100[/tex][tex]\frac{actual yield}{theoretical yield} * 100[/tex]

Substitute the given values in this formula to get the %yield.

[tex]\frac{598g}{945g} * 100\\=63.3[/tex]

Hence, the %yield for the formation of ammonia is ---- 63.3.

Synthesis reaction is the answer

Fe2O3 (s) + CO (g) -> Fe(s) + CO2 (g) (unbalanced)
1.Calculate the number of grams of CO that can react with 0.150kg of Fe2O3
2. Calculate the number of grams of Fe and the number of grams of CO2 formed
when 0.150 kg of Fe2O3 reacts

Answers

Answer:

1. 78.9g of CO

2. 104.9g Fe and 124.0g CO2

Explanation:

Based on the balanced reaction:

Fe2O3 (s) + 3CO (g) -> 2Fe(s) + 3CO2 (g)

1 mole of Fe2O3 reacts with 3 moles of CO to produce 2 moles of Fe and 3 of CO2

1. The moles of 0.150kg = 150g of Fe2O3 -Molar mass: are:

150g * (1mol / 159.69g) = 0.9393 moles Fe2O3

Moles CO:

0.9393 moles Fe2O3 * (3mol CO / 1mol Fe2O3) = 2.818 moles CO

Mass CO -Molar mass: 28.01g/mol-:

2.818 moles CO * (28.01g/mol) = 78.9g of CO

2. The moles of Fe produced are:

0.9393 moles Fe2O3 * (2mol Fe / 1mol Fe2O3) = 1.8786 moles Fe

Mass Fe -Molar mass: 55.845g/mol-:

1.8786 moles Fe * (55.845g/mol) = 104.9g Fe

The moles of CO2 produced are:

0.9393 moles Fe2O3 * (3mol CO2 / 1mol Fe2O3) = 2.818moles CO2

Mass CO2 -Molar mass: 44.01g/mol-:

2.818moles CO2 * (44.01g/mol) = 124.0g CO2

. Calculate the pH and the pOH of each of the following solutions at 25 °C for which the substances ionize completely:
(a) 0.200 M HCl

(b) 0.0143 M NaOH

(c) 3.0 M HNO3

(d) 0.0031 M Ca(OH)2

Answers

a. HCl:
pH= -log [H3O+]
PH=-log (0.200)
= 0.699

poH= 14-0.699
= 13.301

b. NaOH:
PoH= -log [OH-]
= -log (0.0143)
= 1.845
pH= 14-poH
= 14- 1.845
= 12.16

c. HNO3:
PH= -log[H3O+]
=-log(3.0)
= -0.4771
poH= 14-pH
= 14-9-0.4771
= 14.4771

pH= -0.4771, poH= 14.4771

d. [Ca(OH)2] = 0.0031M
[OH-]= 2X0.0031
[OH-] = 0.0062M

PoH= - log[OH-]
=-log(0.0062)
=-log(6.2x10-3)
=-(-2.21)
= 2.21
PH=14-poH
=14-2.21
=11.79
POH=2.21, PH= 11.79

Based on the molarity of the solutions;

For 0.200 M HCl; pH = 0.699, pOH = 13.301For 0.0143 M NaOH; pOH = 1.845, pH = 12.16For 3.0 M HNO3; pH = -0.4771, poH = 14.4771For 0.0031 M Ca(OH)2; pOH = 2.21, pH = 11.79

What pHand pOH?

pH is the negative logarithm to base ten of the hydrogen ions concentration of a solution.

pH = -log[H+]

pOH is the negative logarithm to base ten of the hydroxide ions concentration.

pOH = -log[OH-]

Also;

pH + pOH = 14

For HCl:

pH = -log [H3O+]

pH =-log (0.200)

pH = 0.699

Then;

poH= 14-0.699

pOH = 13.301

For NaOH:

pOH= -log [OH-]

= -log (0.0143)

pOH = 1.845

Then;

pH= 14-poH

= 14- 1.845

pH = 12.16

For HNO3:

pH= -log[H3O+]

=-log(3.0)

= -0.4771

Then;

pOH = 14-9-0.4771

pOH = 14.4771

For [Ca(OH)2]

molarity = 0.0031M

2 moles of OH- are produced

[OH-]= 2 × 0.0031

[OH-] = 0.0062M

pOH = - log[OH-]

=-log(0.0062)

=-log(6.2x10-3)

=-(-2.21)

pOH = 2.21

Then;

pH =14-2.21

pH =11.79

Answers

Answer:

Vaporization

Since the question does not specify what molecule is being acted upon by the increment in temperature, I'll assume it's water.

When first taken out of the fridge, water is in the form of ice, and it has not been affected by a change in temperature yet, so it's at the origin.

(origin = ice)

As you raise the temperature, however, the ice starts to melt, and melting occur during phase 2. You have to keep the temperature constant for the process to properly occur.

(phase 2 = melting)

After it finishes melting, the ice is now in it's liquid state, which is water. The temperature continues to rise in order to proceed to the next phase.

(2nd slope = water)

Lastly, Water is being vaporized during phase 4. Notice, the temperature is kept constant in order to allow the process to properly occur.

(phase 4 = vaporization)

A solution has an [H3O+] of 1 × 10−5 M the [OH−] of the solution will be 1 × 10−9 M and option C is correct.

What is [OH−] of the solution?

The water is made up of H2O only and when the pH of it is 7 then the concentration of all the ions would be the same while dissociation the water will get dissociate into H+ ions and OH- ions.

The concentration of OH- ions will be

OH- = Kw {H3O+}

{H3O+} = 1 × 10−5 M.

Kw = 14

substituting the value in the equation,

OH = 14 { 1 × 10−5 M.}

OH = 1 × 10−9 M

Therefore, the solution has an [H3O+] of 1 × 10−5 M the [OH−] of the solution will be 1 × 10−9 M and option C is correct.
