If you obtain 3.0 grams of aspirin from an experiment that could make no more than 3.14 grams, what is the percent yield?

87%
105%
96%
92%

Answers

Answer 1

Answer:

96%

Explanation:

To find the percent yield, we can use this equation

[tex]\frac{Actual}{Theoretical} *100[/tex]

The actual yield of aspirin is 3.0 and the theoretical is 3.14 in this case, so just plug the numbers in.

[tex]\frac{3.0}{3.14} *100\\\\ =96[/tex]

Thus the percent yield is 96%

What is the percent composition HCN?

Answers

Answer:

see calculations in explanation

Explanation:

percent = part/total x 100%

part = ∑ atomic mass of element

hydrogen = 1.008 amu (atomic mass units)carbon = 12.011 amunitrogen = 14.007 amu

total = ∑ molecular mass of compound

       = H amu  +  C amu +  Namu

       = 1.008 amu + 12.011 amu + 14.007 amu

       = 27.026 amu

%H = (1.008amu/27.026amu)100% = 3.730%

%C = (12.011amu/27.026amu)100% = 44.442%

%N = (14.007amu/27.026amu)100% = 51.827%

Check results ∑%values = 100%

3.730% + 44.442% + 51.827% = 99.999% ≅ 100%

A net force of 66 newtons accelerates a child at 2.0 m/s? down a smooth playground slide. What is the mass of the
child?

A 130 kg
B68 kg
© 64 kg
D 33 kg

Answers

Answer:The answer is D 33

Explanation:

The mass of the child accelerating at 2 m/s² by a net force of 66 N is 33 Kg (Option D)

Relationship between force and acceleration

Force is related to acceleration according to the following equation

Force (F) = mass (m) × acceleration (a)

F = ma

With the above formula, we can obtain the mass of the child

How to determine the mass of the child Acceleration (a) = 2 m/s²Force (F) = 66 NMass (m) =?

F = ma

66 = m × 2

Divide both side by 2

m = 66 / 2

m = 33 Kg

Thus, the mass of the child is 33 Kg

Which of the following is an example of a situation where work occurs?
A

B

D
a baseball soaring through the air

Answers

Answer:

a baseball soaring through the air

Explanation:

According to the passage, “Work occurs whenever something is moved and an object is put into motion.” A baseball soaring through the air is an object in motion.

An example of a situation where work occurs is a baseball soaring through the air. Therefore, option D is correct.

What is work ?

Work is defined as the energy that is applied to or removed from an object by applying force along a displacement. In its simplest form, it equals the product of the force's magnitude and the distance traveled for a constant force directed in the same direction as the motion.

Inertia law. Its name derives from an object's propensity to resist any change in motion up until an out-of-balance force acts on it.

A force that opposes motion is friction. Friction occurs when two moving objects come into touch and operates in the opposite direction.

The angle between force and displacement determines the kind of work that is done. Positive work occurs when a force is applied and an object is moved in that direction.

Thus, option D is correct.

why does a mole of silicon weigh a different amount than a mole of carbon?

Answers

Answer:

[tex]\boxed {\boxed {\sf Different \ amount \ of \ protons, neutrons, \ and \ electrons}}[/tex]

Explanation:

Remember that a mole is equal to Avogadro's number: 6.022*10²³ atoms. Also, remember that an atom is made up of protons, neutrons, and electrons. Each element has a different amount of each.

If an element has more of these particles in 1 atom, then the atomic mass will be greater, ultimately making the molar mass (mass of 1 mole) greater.

Silicon has 14 protons, electrons, and neutrons, making its atomic mass 28.085 amu and its molar mass 28.085 grams. However, carbon only has 6 of each particle, so its atomic mass is smaller at 12.011 amu and molar mass is 12.011 grams.

Calculate the number of particles of each substance based on the number of moles from the balanced equation

Answers

Answer:

KCl ⇒ 1.205x10²⁴ molecules

O₂ ⇒ 1.807x10²⁴ molecules

KClO₃ ⇒ 1.205x10²⁴ molecules

Explanation:

In order to calculate the number of particles from the number of moles, we have to use Avogadro's number, which states the number of particles in one mol:

In 1 mol there are 6.023x10²³ particles (ions, molecules or atoms).

So now we multiply the number of moles of each substance by Avogadro's number:

KCl ⇒ 2 mol * 6.023x10²³ molecules/mol = 1.205x10²⁴ moleculesO₂ ⇒ 3 mol * 6.023x10²³ molecules/mol = 1.807x10²⁴ moleculesKClO₃ ⇒ 2 mol * 6.023x10²³ molecules/mol = 1.205x10²⁴ molecules

To answer this problem we can use Gay-Lussac's law, which states that at a constant volume (such as is the case with a rigid container):

P₁T₂=P₂T₁

Where in this case:

P₁ = 340 kPaT₂ = 273 °C ⇒ 273 + 273.16 = 546 KP₂ = ?T₁ = 713 K

We input the data:

340 kPa * 546 K = P₂ * 713 K

150. g of aluminum chloride in 0.450 liters of solution, what is the concentration? (any examples are helpful, thank you)

Answers

Answer:

2.49 M

Explanation:

Step 1: Given data

Mass of AlCl₃: 150. gVolume of solution: 0.450 L

Step 2: Calculate the moles AlCl₃ (solute)

The molar mass of AlCl₃ is 133.34 g/mol.

150. g × 1 mol/133.34 g = 1.12 mol

Step 3: Calculate the molar concentration of AlCl₃

Molarity is equal to the moles of solute divided by the liters of solution.

M = 1.12 mol/0.450 L = 2.49 M

The energy exists in many different forms. Each form of energy can be converted or changed into the other forms. The geothermal energy denotes the thermal energy.

What is solar energy?

The energy produced from the sun is called the solar energy. The heat and light which come from the sun is the solar energy. The solar energy play an important role in reducing the emissions of green house gases and also control the climate change.

The biomass is known as the fuel obtained from the organic matter waste of the living organisms such as plant waste, animal waste and municipal wastes. It is the fuel developed from plants.

The hydropower is the largest source of renewable energy which uses the moving water to produce electricity. The energy which is generated from the heat within the earth is called the Geothermal energy.
