Explanation:see attached photo

Answer:

[tex]P=0.583atm[/tex]

Explanation:

Hello,

In this case, by using the ideal gas equation:

[tex]PV=nRT[/tex]

We can compute the pressure as shown below, considering the given data and absolute temperature:

[tex]P=\frac{nRT}{V}=\frac{0.325mol*0.082\frac{atm*L}{mol*K}*(35+273)K}{14.08L}\\ \\P=0.583atm[/tex]

Answer:

1.6×10^3 KJ

Explanation:

We must first calculate the number of moles corresponding to 650.50g of sulphur trioxide.

Number of moles = mass of sulphur trioxide/ molar mass of sulphur trioxide

Molar mass of sulphur trioxide= 80.066 g/mol

Given mass of sulphur trioxide= 650.50g

Number of moles = 650.50g / 80.066 g/mol

Number of moles = 8.124 moles of sulphur trioxide

Now from the balanced reaction equation;

Formation of 2 moles of sulphur trioxide evolves 396.8KJ of energy.

Therefore formation of 8.124 moles of sulphur trioxide will evolve;

8.124moles × 396.8 KJ /2 moles = 1611.8KJ or 1.6×10^3 KJ

Answer: A. They absorb radiation given off by the earth.

Explanation: Green house gases are gases that have the capability of trapping the heat energy from the sun in our environment. These special attribute of these gases is what keeps our environment warm and sustain life as we know it. Example of Green House Gases include: carbon dioxide, water vapour and methane.

Answer:

A. THEY ABSORBS RADIATION GIVEN OFF BY THE EARTH.

Explanation:

Greenhouse gases are gases capable of absorbing and emitting infrared  radiations in different wavelength range emitted by the earth. These gases include water vapor, carbon iv oxide, methane, ozone, chlorofluorocarbons, nitric oxide, hydrofluorocarbons. These gases contribute to the greenhouse effects and there actions are dependence on their respective characteristics, abundance in the atmosphere and the indirect effects it causes. Earth surfaces absorbs radiant energy from the sun and these radiations are reflected as light or reflected back to space as hear. Greenhouse gases are involved in absorbing and emitting these incoming energies in order to create a balance between the incoming and outgoing energies. This determines the temperature on the earth surface. The earth can be warm or cold depending on the direction the difference in this balance shifts. Without the greenhouse gases the average temperature of the earth will be lower than the expected temperature.

Answer:

0.264 mol/L

Explanation:

Data obtained from the question includes:

Volume = 5.74L

Mass of FeCl3 = 246 g

Molarity =?

Next, we shall determine the number of mole in 246g of FeCl3.

This is illustrated below:

Mass of FeCl3 = 246g

Molar mass of FeCl3 = 56 + (35.5x3) = 162.5g/mol

Number of mole of FeCl3 =..?

Mole = Mass /Molar Mass

Number of mole of FeCl3 = 246/162.5

Number of mole of FeCl3 = 1.514 mol

Now, we can obtain the molarity of the solution as follow:

Molarity = mole /Volume

Volume = 5.74L

Mole of FeCl3 = 1.514 mol

Molarity = 1.514/5.74

Molarity = 0.264 mol/L

Explanation:

SnO₂ + H₂ + energy → Sn + H₂0

The reaction is between Tin(iv) oxide and hydrogen gas to form tin and water molecules.

Notice the reaction is not balance therefore let us balance the equation. To balance the equation the number of atoms on both side (reactant and product)of the equation must be equal.

SnO₂ +2H₂ → Sn + 2H₂0

The equation is balanced .  SnO₂  has coefficient of 1 , H₂ has coefficient of 2, Sn has coefficient of 1 and H₂0 has coefficient of 2.

Q5

SnO₂ + 2H₂→ Sn + 2H₂0

1 moles of SnO₂ will balance the equation

Q6

The reactant is on the left side of the chemical equation. Therefore the reactants are Tin(iv) oxide and hydrogen molecules (SnO₂ and H₂)

Q7

The product is on the right side of the chemical equations .Therefore, the products are Tin and water molecules(Sn and H₂0).

Q8

The reaction is an endothermic reaction because it absorb heat from it environment.

Answer:

Wavelength of sound waves[tex]\ambda = 386[/tex] millimetres

Explanation:

The speed of any wave is equal to the product of its wavelength and frequency.

This can be represented mathematically as

[tex]V = f* \lambda[/tex]

Where

V is the speed of sound waves

f is the frequency of sound waves

and

[tex]\lambda[/tex] is the wavelength of the sound waves.

Substituting the given values in above equation we get -

[tex]340 = f * \lambda\\\lambda = \frac{340}{880} \\[/tex]

[tex]\lambda = 0.386[/tex] meters

[tex]\ambda = 386[/tex] millimetres

Answer:

Troposphere

Explanation:

The troposphere is the lowest layer of Earth's atmosphere that extends from under the stratosphere down to the surface of the earth. Nearly all weather condition takes place in the troposphere. The troposphere contains about 75% of the atmosphere's mass and 99% of the total mass of water vapour and aerosols in the atmosphere.

Answer: Pressure decreases.

Explanation:

Atmospheric pressure is termed as the  downward force applied by the weight of air against a particular area on Earth's surface.  the Standard atmospheric pressure is determined  by weighing the column of air occupying  1 square inch on Earth's surface which begins  at sea level and moves  upward to the uppermost layer of the atmosphere

Measuring the Atmospheric pressure from sea level to the stratosphere,the second layer of the atmosphere which contains the most of the ozone gas show that the pressure decreases

Answer:

110L

Explanation:

The following data were obtained from the question:

Initial volume (V1) = 44L

Initial temperature (T1) = 200K

Final temperature (T2) = 500K

Final volume (V2) =..?

The new volume of the balloon can be obtained by using Charles' law equation as shown below:

V1/T1 = V2/T2

44/200 = V2/500

Cross multiply

200 x V2 = 44 x 500

Divide both side by 200

V2 = 44 x 500/200

V2 = 110L

Therefore, the new volume of the balloon is 110L

Answer:

The carbon footprint of one plastic bottle of mass 23.5 g is 34.390 g.

Explanation:

The carbon footprint of one plastic bottle can be estimated by simple rule of three. That is:

[tex]x = \frac{23.5\,g}{4100\,g}\times 6000\,g[/tex]

[tex]x = 34.390\,g[/tex]

The carbon footprint of one plastic bottle of mass 23.5 g is 34.390 g.

Answer:

213.4°C.

Explanation:

Data obtained from the question:

Initial pressure (P1) = 5.1atm

Initial temperature (T1) = 45°C = 45°C + 273 = 318K

Final pressure (P2) = 7.8atm

Final temperature (T2) =..?

The new temperature can be obtained as follow:

P1/T1 = P2 /T2

5.1/318 = 7.8/T2

Cross multiply

5.1 x T2 = 318 x 7. 8

Divide both side by 5.1

T2 = 318 x 7. 8 /5.1

T2 = 486.4K

Finally, we shall convert 486.4K to celsius temperature. This can be done as follow:

T(°C) = T(K) – 273

T(K) = 486.4K

T(°C) = 486.4 – 273

T(°C) = 213.4°C.

Therefore, the new temperature is 213.4°C

Identical twins came from the same sperm and egg, so they have the same chromosomes and genes. ... As identical twins get older they may look more and more different, because they are exposed to more diverse environments. The science of epigenetics explains how these environmental influences can affect the genes.

The color changes occurs in hair might caused by life styles and diet irrespective of the genetical traits. The damaged pigment cells causes the gray hair.

Each characteristics in a living thing is coded by genes in them. These codes corresponding to some behaviors are called genetic traits. The pigment melamine make the hair black.

Variation in the pigment makes the color variation in hair also. Gray hair may appear on anyone at any age. Some people begin to go grey as early as when they are in high school or college.

Our genes decide when we begin to grey our hair. That a result, the majority of us will start ageing at around the same time as our parents or grandparents did.

However, our lifestyle and diet also influence the hair and skin color. Therefore, there might have differences in appearance of twins too.
