Explanation:

An industrial synthesis of urea obtains 87.5 kg of urea upon reaction of 68.2 kg of ammonia with excess carbon dioxide. Determine the theoretical yield of urea and percent yield for the reaction.

Answers

Answer:

The theoretical yield of urea = 120.35kg

The percent yield for the reaction = 72.70%

Explanation:

Lets calculate -

The given reaction is -

[tex]2NH_3(aq)+CO_2[/tex] →[tex]CH_4N_2O(aq)+H_2O (l)[/tex]

Molar mass of urea [tex]CH_4N_2O[/tex]= 60g/mole

Moles of [tex]NH_3[/tex] = [tex]\frac{62.8kg/mole}{17g/mole}[/tex] (since [tex]Moles=\frac{mass of substance}{mass of one mole}[/tex])

                     = 4011.76 moles

Moles of [tex]CO_2[/tex] = [tex]\frac{105kg}{44g/mole}[/tex]

                = [tex]\frac{105000g}{44g/mole}[/tex]

                = 2386.36 moles

Theoritically , moles of [tex]NH_3[/tex] required = double the moles of [tex]CO_2[/tex]

    but , [tex]4011.76<2\times 2386.36[/tex] , the limiting reagent is [tex]NH_3[/tex]

Theoritical moles of urea obtained = [tex]\frac{1 mole CH_4N_2O}{2mole NH_3}\times4011.76 mole NH_3[/tex]

                                                      = [tex]2005.88mole CH_4N_2O[/tex]

Mass of 2005.88 mole of [tex]CH_4N_2O[/tex] =[tex]2005.88 mole \times\frac{60g CH_4N_2O}{1mole CH_4N_2O}[/tex]

                                                     = 120352.8g

                                                     [tex]120352.8g\times \frac{1kg}{1000g}[/tex]

                                                     = 120.35kg

Therefore , theroritical yeild of urea = 120.35kg

Now , Percent yeild = [tex]\frac{87.5kg}{120.35kg}\times100[/tex]

                                 72.70%

Thus , the percent yeild for the reaction is 72.70%

If 0.0015 moles of NaOH is dissolved in 11 L of water, what is the pH of the
solution?

Answers

Answer:

pH = 10.15

Explanation:

NaOH is a strong base so it dissolves completely.

Calculate your [OH-] first by dividing the moles of OH- by the volume.

0.0015 mol OH- / 11 L = 0.00014

Then, calculate the pOH:

pOH = -log[OH-] = -log(0.00014) = 3.85

pOH + pH = 14, so pH = 14 - pOH = 14 - 3.85 = 10.15

Which of the following chemical equations follows the law of conservation of mass?

Answers

Answer:

The third choice

Explanation:

The law of conservation of mass tells us that the mass of the reactants and products in a chemical reaction will be equal to one another. Equations follow the law of conservation of mass when they are balanced, which means that they have the same number and type of atoms on each side.

When individual atoms are counted, the third choice has the same number and type of atoms on each side: 1 gallium, three cesium and three fluorine.

What is empirical formula?

The easiest whole-number proportion of the numerous elements in a molecule is represented by an empirical formula.

Calculation of empirical formula

Given data:

C = 11.0 g

H = 4.5 g

The atomic mass of C = 12

The atomic mass of H = 1

Now, divide the mass by atomic mass.

1) For carbon atom= 11 / 12 =0.91

2) For hydrogen atom = 4.5 / 1=4.5

Now, divide the lowest term by the obtaining whole number.

1) For carbon atom = 11/ 0.91 = 12

2) For hydrogen atom = 4.5/0.91 = 5

Therefore, the empirical formula will be C2H,

The Voting Rights Act, signed into law in August 1965, suspended literacy tests and provided for the appointment of federal examiners with the power to register qualified citizens to vote.
