What are molecules ?

A molecule is the smallest unit of a material that keeps its content and properties. It is composed of two or more atoms that are joined together by chemical bonds. Chemistry is built upon molecules. The element symbol and a subscript indicating the number many atoms are used to identify molecules.

How are molecules created?

Atoms interact with each other and with their nuclei when they are close to one another. A molecule is created whenever two or more atoms combine in a way that lowers the state's overall energy.

Answers

Step 1 - Understanding the relation of potential energy, kinectic energy and the conservation of energy

The potential energy is the energy related to a body that can start moving under the influence of a force anytime soon.

The kinf of potential energy depends on the force that could act on the body. When a body is lifted, because gravity can pull it back, we say that this body has gravitational potential energy

Kinetic energy, on the other hand, is related to actual movement. It depends on the mass as well as on the velocity of the body. When we lift an object and drop it next, all the potential energy will be converted to kinetic energy, i.e., the velocity of the object we dropped will be also proportional to the height. It cannot gain more energy.

Step 2 - Interpreting the problem

Now that we know how potential and kinetic energy work, we can start working on the problem. Since potential energy is directly proportional to height, the highest potential energy would be attained at F.

The lowest potential energy, on the other hand, woud be attained at D, i.e., the smaller height.

The highest kinetic energy would be attained when all the potential energy is converted to kinetic energy, i.e., when the bicyclist, starting at A, loses its potential energy reaching D

The speed is directly proportional to the kinetic energy: the higher the speed, the higher the kinetic energy. Since the kinetic energy, as we saw, is the greatest at D, the velocity will also be the greatest at this point.

Answers

Sulfuric acid is a strong acid, which means it can dissociate completely when dissolve in water. In other words, the reactant H2SO4 is completely soluble in water, otherwise, it wouldn't be a strong acid.

On other hand, the second reactant Ba(OH)2 is soluble in water because it's a strong base, which are bases that completely dissociate when dissolve in water.

Therefore, sulfuric acid (H2SO4) is soluble in water and the barium hydroxide (Ba(OH)2) is also soluble in water.

Sulfur and fluorine react in a combination reaction to produce sulfur hexafluoride:

S (s) + 3F2(g) → SF6 (g)

The maximum amount of SF6 that can be produced from the reaction of 32.1 g of sulfur with 114g of fluorine is ________ g.

Answers

Taking into account the reaction stoichiometry, the maximum amount of SF₆ that can be produced from the reaction of 32.1 g of sulfur with 114 g of fluorine is 146.46 grams.

Reaction stoichiometry

In first place, the balanced reaction is:

S + 3 F₂  → SF₆

By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:

S: 1 molesF₂: 3 molesSF₆: 1 mole

The molar mass of the compounds is:

S: 32 g/moleF₂: 19 g/moleSF₆: 146 g/mole

By reaction stoichiometry, the following mass quantities of each compound participate in the reaction:

S: 1 mole ×32 g/mole= 32 gramsF₂: 3 moles ×19 g/mole= 57 gramsSF₆: 1 mole ×146 g/mole= 146 grams

Limiting reagent

The limiting reagent is one that is consumed first in its entirety, determining the amount of product in the reaction.

Limiting reagent in this case

To determine the limiting reagent, it is possible to use a simple rule of three as follows: if by stoichiometry 57 grams of F₂ reacts with 32 grams of S, 114 grams of F₂ reacts with how much mass of S?

mass of F₂= (114 grams of F₂× 32 grams of S)÷ 57 grams of F₂

mass of F₂= 64 grams

But 64 grams of F₂ are not available, 32.1 grams are available. Since you have less mass than you need to react with 114 grams of F₂, S will be the limiting reagent.

Mass of SF₆ formed

Considering the limiting reagent, the following rule of three can be applied: if by reaction stoichiometry 32 grams of S form 146 grams of SF₆, 32.1 grams of S form how much mass of SF₆?

mass of SF₆= (32.1 grams of S× 146 grams of SF₆)÷ 32 grams of S

mass of SF₆= 146.46 grams

Finally, 146.46 grams of SF₆ can be produced from the reaction of 32.1 g of S with 114 g of F₂.

Liquid octane (CH₂(CH₂)6 CH₂) reacts with gaseous oxygen gas (₂) to produce gaseous carbon dioxide (CO₂) & gaseous water (H₂O). If 85.8g of carbon dioxide is produced from the reaction of 31.98g of octane. & 190.4g of oxygen gas, calculate the percent yield of carbon dioxide.

Answers

The percent yield of carbon dioxide is 87%.

The balanced chemical equation for reaction of octane with oxygen,

CH₂(CH₂)₆CH₂+ 12O₂ → 8CO₂ + 8H₂O

We can use the mole concept here,

Mole = Given mass/molar mass.

From the reaction,

1 mole of Octane = 8 moles of carbon dioxide.

Now, moles of octane N,

N = 31.98/114.23

N = 0.2799

Moles of Carbon dioxide = 8 x 0.2799

Moles of Carbon dioxide = 2.239

Mass of CO₂ formed,

2.239 = Mass of CO₂/44

Mass of CO₂ = 98.54 grams/mole.

Percentage yield = theoretical mass/experimental mass x 100

Theoretical mass = 98.54 grams/mole.

Experimental mass = 85.8 grams/mole.

Percentage yield of CO₂ = 85.8/98.54 x 100

b) Beta Particles

c) Gamma rays

Alpha Particles

Alpha particles are essentially helium atoms. When radiated, the value 4 is subtracted from the parent's molecule mass number while the value 2 is subtracted from the parent's molecule atomic number. Due to their heaviness, they are less penetrative, compared to other radiation types. They are positively charged.

The volume of the oxygen into a balloon is, V = 1.70 ml.

Equation :

To calculate the volume of the oxygen using the formula

PV = nRT

where,

P is pressure

V is volume

n is number of moles

R is gas constant

T is temperature

So, the known values are :

P = 1183 mmHg

R = 8.314 J/mol

T = 151.4°F = 66.33°C

mass = 58.41g

n = ?

V = ?

While we don't know the value of n but we know mass so we can calculate number of mole by using formula,

n = m / M

That is,

n is number of mole

m is mass

M is molecular mass

Now, putting values in this

n = 58.41 / 15.99

n = 3.65 mol

Thus, now we know the value of n

Put the value in formula

PV =nRT

1183 mmHg x V = 3.65 mol x 8.314 J/mol x 66.33°C

V = 2012.86 / 1183

Answers

The new temperature of certain quantity of helium gas is at a temperature of 27°C and a pressure of 1.00 atm will be 300 K if its volume is doubled at the same time that its pressure is decreased to one-half its original value.

We will use combined gas law equation to find the new temperature.

We know that

Initial temperature T₁ = 27°c +273 K = 300 K

Initial pressure P₁ = 1.00 ATM

Initial volume V₁ = V

Final volume V₂ = 2 V

Final pressure P₂ = P/2 = 1/2 = 0.5 atm

Now, using the combined gas law equation, which is given as -

P₁V₁ = P₂V₂

 T₁       T₂

where,

P₁ = Initial pressure

P₂ = Final pressure

V₁ = Initial volume

V₂ = Final volume

T₁ = Initial temperature

T₂= Final temperature

Avogadro's law states that equal volumes of gases contains equal number of molecules at same temperature and pressure.

P₁V₁T₂ = P₂V₂T₁

Dividing P₁V₁ on both the sides

P₁V₁T₂  =  P₂V₂T₁

P₁V₁           P₁V₁

We get,

T₂ = P₂V₂T₁

        P₁V₁

Substituting values,

T₂ = 0.5 × 2V × 300 × V

                           1

T₂ = 300K

Hence, the new temperature is 300 K.
