Surface currents are driven by Wind.

Wind blows in patterns due to the Coriolis effect

Ocean surface currents are typically created by wind. On the northern and southern hemispheres, the revolution occurs in a clockwise and an anticlockwise direction, respectively. The Coriolis effect has a significant impact on the wind's characteristics and pattern.

The climate is influenced by wind patterns, and the Coriolis effect, a byproduct of the rotation of the earth, has an impact on the curvature of the wind mass. The equator's wind rises in this process from the northeast of the Northern Hemisphere.

Answer

The pressure inside the cylinder will change to 14.686 atm

Explanation

Given:

Volume, V = 0.500 L

Moles of O2 = 0.150 mol

Temperature, T = 25 °C = (25 + 273.15 K) = 298.15 K

Step-by-step solution:

The first step is to calculate the pressure exerted by O2 using ideal gas equation:

Plugging the values of the parameters into the formula:

The pressure exerted by O2 = 7.343 atm

If 0.150 mol of sulfur dioxide, SO2 was added to the oxygen gas already in the cylinder, then the pressure inside the cylinder will change by a factor of 2. That is:

Total pressure will be = 2 x 7.343 atm = 14.686 atm

Or the total pressure can be calculated using the ideal equation above, and putting n = 0.150 mol + 0.150 mol = 0.3 mol

The energy of the photon of light can be obtained as 6.27 * 10^-20 J.

We know that a photon has to to do with a particular unit of light. We know that light can be said to be composed of very tiny corpuscles and these corpuscles of light is what we call the photon of the light.

We can be able to us the equation that is derived by Max Plank to be able to get the value of the energy of the photon of light. Now we know that a photon of light can have an energy that is able to be obtained by;

E = hf

h = Plank's constant

f = Frequency

Then;

E = 6.6 * 10^-34 Js * 9.5 * 10^13 Hz

= 6.27 * 10^-20 J

Answer and Explanation: Sample A is a mixture. Solubility is characteristics of each substance, which means a substance can be distinguished from other substances and can be useful to separate mixtures.

In Sample A, when is added different volumes of water, the resulting powder has different mass. This means there are more than one substance forming the yellow cube. Therefore, sample A is a mixture.

Sample B is a pure substance. Each substance has its own melting point. Whe na pure substance reaches its melting point, temperature is constant until all of that substance is melted. In sample B, temperature is stable at 66.2°C and then, after all the powder is melted, it rises again. Therefore, sample B is a pure substance.

When water is carefully dropped onto the surface of a penny, it can form a dome before spilling over the small lip around the penny's perimeter. Rubbing alcohol can also accumulate, but it will spill before forming a well-rounded dome.

Cohesive forces are powerful, but not invincible. The force of gravity on the water molecules will eventually overcome the cohesive forces as a water drop builds up and out, usually bulging over the sides of the penny. The "skin" will rupture, allowing all the water to escape.

When the drops of water you add to the penny reach the penny's edge, the cohesion and surface tension of water become apparent.

Thus, When the water reaches the edge, a bubble or dome of water begins to form on top of the penny.

2) The heat capacity of aluminum is 219.44 J/mol.°C.

3) a) the experimental ΔHs of ice is -0.154 kJ/mol.

b) too high

Calculate the heat released by the aluminum:

q = mcΔT

where q = heat released, m = mass of aluminum, c = specific heat capacity of water and ΔT = change in temperature.

q = (24.7 g) (0.903 J/g°C) (100.0°C - 23.4°C)

q = 18643.26 J

Next, calculate the heat absorbed by the calorimeter:

q = mcΔT

q = (99.5 g + 24.7 g) (15.8 J/°C) (23.4°C - 19.5°C)

q = 4009.92 J

The heat released by the aluminum is equal to the heat absorbed by the calorimeter and water:

18643.26 J = 4009.92 J + q3

where q3 = heat absorbed by the water.

q3 = 14633.34 J

Calculate the molar heat capacity of aluminum:

Cp,m = q3 / (nΔT)

where Cp,m = molar heat capacity, n = number of moles of aluminum, and ΔT = change in temperature.

n = m / M

where m = mass of aluminum and M = molar mass of aluminum (26.98 g/mol).

n = 24.7 g / 26.98 g/mol

n = 0.916 mol

Cp,m = 14633.34 J / (0.916 mol * 76.6°C)

Cp,m = 219.44 J/mol.°C

Therefore, the heat capacity of aluminum is 219.44 J/mol.°C.

3) (a) To calculate the experimental ΔHs of ice, we first need to calculate the heat gained by the water and the heat lost by the ice during the process.

Heat gained by water = mass of water × specific heat capacity of water × change in temperature

= 100.0 g × 4.184 J/g·°C × (-20.1°C)

= -8,423.84 J

Heat lost by ice = mass of ice × heat of fusion of ice

= 25.6 g × 6.01 kJ/mol

= 154.496 J

Since the process is assumed to be adiabatic (no heat exchange with the surroundings), the heat gained by the water must be equal to the heat lost by the ice.

Thus, -8,423.84 J = 154.496 J = -8,269.344 J

The negative sign indicates that the process is exothermic. Therefore, the experimental ΔHs of ice is:

ΔHs = -154.496 J/mol = -0.154 kJ/mol

(b) If the student forgets to include the calorimeter term in the calculation, the calculated ΔHs of ice will be too high. This is because the heat absorbed by the calorimeter during the process is not accounted for, leading to an overestimation of the heat gained by the water and underestimation of the heat lost by the ice.

Answer:

Option A. LR = N2O4, 45.7g N2 formed

Explanation:

The balanced equation for the reaction is given below:

N2O4(l) + 2N2H4(l) → 3N2(g) + 4H2O(g)

Next, we shall determine the masses of N2O4 and N2H4 that reacted and mass of N2 produced from the balanced equation. This is illustrated below:

Molar mass of N2O4 = 92.02 g/mol

Mass of N2O4 from the balanced equation = 1 x 92.02 = 92.02 g

Molar mass of N2H4 = 32.05 g/mol

Mass of N2H4 from the balanced equation = 2 x 32.05 = 64.1g

Molar mass of N2 = 2x14.01 = 28.02g/mol

Mass of N2 from the balanced equation = 3 x 28.02 = 84.06g

Summary:

From the balanced equation above,

92.02g of N2O4 reacted with 64.1g of N2H4 to produce 84.06g of N2.

Next, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above,

92.02g of N2O4 reacted with 64.1g of N2H4.

Therefore, 50g of N2O4 will react with = (50 x 64.1)/92.02 = 34.83g of N2H4.

From the calculations made above, we can see that only 34.83g out 45g of N2H4 is required to react completely with 50g of N2O4.

Therefore, N2O4 is the limiting reactant and N2H4 is the excess reactant.

Finally, we shall determine the mass of N2 produced from the reaction.

In this case the limiting reactant will be used as it will produce the maximum yield of N2 since all of it is used up in the reaction.

The limiting reactant is N2O4 and the mass N2 produced can be obtained as illustrated below:

From the balanced equation above,

92.02g of N2O4 reacted to produce 84.06g of N2.

Therefore 50g of N2O4 will react to produce = (50 x 84.06)/92.02 = 45.7g of N2.

Therefore, 45.7g of N2 were produced from the reaction.

At the end of the day,

The limiting reactant is N2O4 and 45.7g of N2 were produced from the reaction.

Do 19565 ft × 3.28084 ft ...than

answer will come in meter than convert it into kilo meter

Answer:

58,040 Joules

Explanation:

To calculate the amount of heat that will be added to the water, we can use the formula:

Q = m × c × ΔT

∴ Q is the amount of heat, m is the mass of the water, c is the specific heat of water, and ΔT is the change in temperature.

Given:

Mass of water (m) = 250 g

Specific heat of water (c) = 4.184 J/g°C

Change in temperature (ΔT) = 80°C - 25°C = 55°C

Plugging these values into the formula, we get:

Q = 250 g × 4.184 J/g°C × 55°C

Q = 58,040 J

Therefore, the amount of heat that will be added to the 250 g of water is 58,040 Joules.

58,040 J is the amount of heat that will be added to 250 g of water to raise the temperature from 25°C to 80°C.

Heat is the energy that moves from one substance to another if the temperatures are different. Heat passes from the hotter to the colder body when two bodies with differing temperatures are brought together. Usually, but just not always, this energy transfer leads to an increase inside the temperature of a colder body and a fall inside the temperature of a hotter body.

By transitioning from one physical state (and phase) to another, such as from a solid to a liquid state (melting), from such a solid to a vapour (sublimation), from such a liquid to a vapour (boiling), either from one solid form to another, a substance can absorb heat without increasing in temperature. 

Q = m × c × ΔT

Q = heat

m =mass

c = specific heat

ΔT = temperature.

(m) = 250 g

(c) = 4.184 J/g°C

(ΔT) = 80°C - 25°C = 55°C

Q = 250 g × 4.184 J/g°C × 55°C

Q = 58,040 J

Therefore, 58,040 J is the amount of heat that will be added to 250 g of water to raise the temperature from 25°C to 80°C.
