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%

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.

The core of earth is made of iron and nickel the outer core is so hot that it melts metal. The inner core is solid. What causes these diffrences

Answers

Answer:

The inner core is solid by intense pressure of all the layers above it.

Explanation:

The inner core is made up of heavy elements such as iron and nickel. It therefore possesses an unusually high pressure that makes the expanded inner core which arose from effects of high temperature to be nullified.

Thus, we can say that the inner core is solid by intense pressure of all the layers above it.

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,

Explain your observations in term of how tempurature affects paritcle motion and how liquid changes to a solid

Answers

Answer:

See explanation

Explanation:

Temperature is defined as a measure of the average kinetic energy of the molecules of a body.

When a substance is heated, the kinetic energy of its molecules increases as the temperature increases; hence the particles of the substance moves faster with increasing temperature.

When heat is withdrawn from a liquid, the temperature decreases and the average kinetic energy of the molecules decreases. The molecules become less energetic hence the liquid changes into solid

Turbo or supercharger

Answers

Honestly I like turbocharged.
Each can be used to increase power, fuel economy, or both, and each has pros and cons. But superchargers can provide their boost almost instantly, whereas turbochargers typically suffer some response lag while the exhaust pressure required to spin the turbine builds. So I would recommend a supercharger.

What is the mass of an atom with 8 protons, 8 electrons, and 8 neutrons?

Answers

Answer:An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999.

Explanation:

The mass of the atom with 8 protons, 8 electrons, and 8 neutrons would be approximately 16 atomic mass units as the number of electrons has an almost negligible contribution to the mass of the atom.

What is atomic mass?

It is the sum of the mass of all the protons as well as the neutrons that are present inside the nucleus.

Atomic mass = total number of protons present in the nucleus + total number of neutrons present in the nucleus of an atom,

As given in the problem we have to find the atomic mass of the atom with  eight protons, eight electrons, and eight neutrons,

This given specified atom clearly represents the oxygen atom as it has eight electrons protons and neutrons each.

Thus, the atomic mass of the given atom would be 16.

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
