Answer:

The false statement is - Air typically moves from areas of lower pressure to areas of higher pressure.

Explanation:

The wind is the air movement that takes place due to pressure differences or the temperature difference of air. Air moves from the higher pressure area to the lower pressure area. The more the difference will be the faster the air will move to a low-pressure area.

Precipitation is a form of water that falls from clouds to earth, it can be rainfall, snow and other forms. Dew is one of the forms that occur when the air cools down to the dew point and form droplets.

Answer:

Air typically moves from areas of lower pressure to areas of higher pressure.

¡Hola!

En este caso, dado que estamos tratando con problem sobre porcentaje peso/peso de hierro, arena, cobre y aluminio, primero debemos calcular la masa inicial de estos dos primeros en la mezcla original de acuerdo con:

[tex]m_{hierro}=300g*0.60=180g\\\\m_{arena}=300*0.40=120g[/tex]

Ahora si podemos calcular la masa de la mezcla final como la suma de las masas de todos los constituyentes de la mezcla:

[tex]m_T=180g+120g+135g+2.77g=437.77g[/tex]

Finalmente, podemos calcular los porcentajes P/P como se muestra a continuación:

[tex]\%P/P_{hierro}=\frac{180g}{437.77g} *100\%=41.1\%\\\\\%P/P_{arena}=\frac{120g}{437.77g} *100\%=24.4\%\\\\\%P/P_{cobre}=\frac{135g}{437.77g} *100\%=30.8\%\\\\\%P/P_{aluminio}=\frac{g}{437.77g} *100\%=0.6\%[/tex]

Answer:

0.897 J/g.⁰C

Explanation:

Given the following data:

m = 170 g (mass)

ΔT = 20.0⁰C (change in temperature)

q = 3050 J (amount of heat)

The amount of heat (q) is calculated as follows:

q = m x Cp x ΔT

Thus, we introduce the data in the mathematical expression to calculate the specific heat (Cp):

Cp = q/(m x ΔT) = 3050 J/(170 g x 20.0⁰C) = 0.897 J/g.⁰C

There are approximately 1.204 x 10²⁴ oxygen atoms in 75 g of SO₃.

To calculate the number of oxygen atoms in 75 g of SO₃, we need to consider the molar mass of SO₃ and Avogadro's number.

The molar mass of SO₃ is calculated as follows:

Sulfur (S) = 32.07 g/mol

Oxygen (O) = 3 x 16.00 g/mol = 48.00 g/mol

Total molar mass of SO₍ = 32.07 g/mol + 48.00 g/mol = 80.07 g/mol

Next, we need to determine the number of moles of SO₃ in 75 g:

moles = mass / molar mass = 75 g / 80.07 g/mol ≈ 0.9369 mol

Since each molecule of SO₃ contains 3 oxygen atoms, we can calculate the number of oxygen atoms by multiplying the number of moles of SO₃ by Avogadro's number (6.022 x 10²³ atoms/mol) and then multiplying by 3:

Number of oxygen atoms = 0.9369 mol x 6.022 x 10²³ atoms/mol x 3 = 1.604 x 10²⁴ atoms

Therefore, there are approximately 1.204 x 10²⁴ oxygen atoms in 75 g of SO₃.

Answer:

1. direct current. 2. electrical power

Explanation

i believe number 2 is right

Answer:

A. L•atm/mol K

Explanation:

The ideal gas law equation is given as follows:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant

T = temperature (K)

As rightly stated in this question, R is the ideal gas constant, which can be different depending on the unit of the other components.

At STP;

V = 22.4L

P = 1 atm

T = 273 K

n = 1 mole

Hence, using PV = nRT

R = PV/nT

R = 1 × 22.4/1 × 273

R = 22.4/273

R = 0.08205

Approximately, R = 0.0821

With the units of P as atm, V as L, n as mol and T as K; R will be 0.0821 L•atm/mol K

Answer:

1. 9.57 × 10^-9 moles.

2. 7.38mol

Explanation:

1.) To find the number of moles there are in the number of particles in an atom, we divide the number of particles (nA) by Avagadro's constant (6.02 × 10^23)

Hence, to find the number of moles (n) of Manganese (Mn), we say:

5.76 x 10^15 atoms ÷ 6.02 × 10^23

5.76/6.02 × 10^(15-23)

= 0.957 × 10^-8

= 9.57 × 10^-9 moles.

2.) Mole = mass/molar mass

Molar mass of sodium chloride (NaCl) = 23 + 35.5

= 58.5g/mol

mole = 431.6 g ÷ 58.5g/mol

mole = 7.38mol

Answer:

Distance

Explanation:

Answer:

Decrease occur in the amount and flow of water bodies.

Explanation:

There is decrease in the amount and flow of water from water bodies such as rivers and lakes etc occur when the river is diverted from large water bodies because the water flows to the diverted sides and decrease occurs in the amount of water in the rivers and lakes. Those regions from where this river passes can also be negatively affected due to low amount of water they receives for their daily needs or for cultivation of crops so we can say that this diversion has adverse effect on other populations.

Answer:

29.42 Litres

Explanation:

The general/ideal gas equation is used to solve this question as follows:

PV = nRT

Where;

P = pressure (atm)

V = volume (L)

n = number of moles (mol)

R = gas law constant (0.0821 Latm/molK)

T = temperature (K

According to the information provided in this question;

mass of nitrogen gas (N2) = 25g

Pressure = 0.785 atm

Temperature = 315K

Volume = ?

To calculate the number of moles (n) of N2, we use:

mole = mass/molar mass

Molar mass of N2 = 14(2) = 28g/mol

mole = 25/28

mole = 0.893mol

Using PV = nRT

V = nRT/P

V = (0.893 × 0.0821 × 315) ÷ 0.785

V = 23.09 ÷ 0.785

V = 29.42 Litres

Dig into the zone of aeration

Explanation:

Within the lithosphere of the earth's surface, the zone of aeration is the zone directly above the water table, with a lot of pore spaces within the rocks. These pore spaces contain air and water, which can be used to water the cows.

Once the zone of aeration has been dug into, the farmer can tap into the underground reserve of water, which is stored within the pores of rocks. This water can now sip into the hole that was dug up by the farmer, forming a pond for the cows.

radioactive decay is  45 ×10¹⁴ J.

The ability to do work is called energy.

The Einstein's formula can be used to find the energy released. Energy is the product of mass  and  the velocity of light in a vacuum squared.

Given that the mass is 0.05 kg and speed of light in vacuum is 3×10⁸ m/s.

Answer:

Mechanical Sound Waves

A mechanical wave is a wave that depends on the oscillation of matter, meaning that it transfers energy through a medium to propagate. These waves require an initial energy input that then travels through the medium until the initial energy is effectively transferred. Examples of mechanical waves in nature include water waves, sound waves, seismic waves and internal water waves, which occur due to density differences in a body of water. There are three types of mechanical waves: transverse waves, longitudinal waves, and surface waves.

Why is sound a mechanical wave? Sound waves move through air by displacing air particles in a chain reaction. As one particle is displaced from its equilibrium position, it pushes or pulls on neighboring molecules, causing them to be displaced from their equilibrium. As particles continue to displace one another with mechanical vibrations, the disturbance is transported throughout the medium. These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves. Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave.
