Answer:

A. The Coriolis Effect bends them

Explanation:

The Coriolis Effect is a force that causes objects and other things that are not attached to the ground and which are moving over a large distance around the Earth such as the trade winds or air planes, to take an apparent curved path in their motion rather than moving in a straight line, due mainly to the rotation of the Earth

The Coriolis Effect is named after French mathematical physicist Gaspard-Gustave de Coriolis

Answer:

Part (1a): The number of moles are 2.14 moles.

Part (1b): The number of moles are 12.2 moles.

Part (1c): The number of moles are 0.545 moles.

Part 2: The number of molecules are 1.38 × 10²⁵.

Part 3: The number of moles are 5.65 moles.

Part 4: The number of atoms are 1.81 × 10²⁴.

Part 5: The number of molecules are 1.20 × 10²⁶.

Explanation:

According to the mole concept:

1 mole of substance contains 6.022 × 10²³ number of atoms or molecules.

Part (1a): 1.29 × 10²⁴ hydrogen atoms in H

As, 6.022 × 10²³ number of hydrogen atoms present in 1 mole

So, 1.29 × 10²⁴ number of hydrogen atoms present in [tex]\frac{1.29\times 10^{24}}{6.022\times 10^{23}}=2.14[/tex] mole

Part (1b): 7.36 × 10²⁴ oxygen atoms

As, 6.022 × 10²³ number of oxygen atoms present in 1 mole

So, 7.36 × 10²⁴ number of oxygen atoms present in [tex]\frac{7.36\times 10^{24}}{6.022\times 10^{23}}=12.2[/tex] mole

Part (1c): 3.28 × 10²³ Na atoms

As, 6.022 × 10²³ number of Na atoms present in 1 mole

So, 3.28 × 10²³ number of Na atoms present in [tex]\frac{3.28\times 10^{23}}{6.022\times 10^{23}}=0.545[/tex] mole

Part 2:

As, 1 mole of oxygen contains 6.022 × 10²³ number of molecules

So, 23.0 moles of oxygen contains 23.0 × 6.022 × 10²³ = 1.38 × 10²⁵ number of molecules

Part 3:

As, 6.022 × 10²³ number of H₂SO₄ molecules present in 1 mole

So, 3.4 × 10 number of H₂SO₄ molecules present in [tex]\frac{3.4\times 10}{6.022\times 10^{23}}=5.65[/tex] mole

Part 4:

As, 1 mole of Na contains 6.022 × 10²³ number of atoms

So, 3.0 moles of Na contains 3.0 × 6.022 × 10²³ = 1.81 × 10²⁴ number of atoms

Part 5:

As, 1 mole of O₃ contains 6.022 × 10²³ number of molecules

So, 200 moles of O₃ contains 200 × 6.022 × 10²³ = 1.20 × 10²⁶ number of molecules

Answer:

See explanation

Explanation:

According to Avogadro's law, the volume of a given mass of gas is directly proportional to the number of molecules of gas present at constant temperature and pressure.

Hence; V1/n1 = V2/n2

The implication of this is, if there were X molecules present and the volume of the balloon is halved, the number of molecules of gas present is also halved. So, we now have X/2 number of gas molecules present in the balloon.

This is in accordance with the statement of Avogadro's law.

Answer:

1.06 × 10^5 J

Explanation:

We have to use the formula;

log(k2/k1) = Ea/2.303 ×R (1/T1 - 1/T2)

Given that;

k1 = 1.10 × 10-4 s-1

k2= 1.02 × 10-3 s-1

Ea=?

R=8.314 Jmol-1K-1

T1= 470. °C

T2= 510. °C

Hence;

log(1.02 × 10-3 s-1/1.10 × 10-4 =Ea/2.303 ×8.314(1/470 -1/510)

0.9672 = Ea/19.122(2.13 - 1.96) × 10^-3

0.9672= Ea/19.122(0.17) × 10^-3

0.9672= 1.7 ×10^-4 Ea/19.122

19.122 × 0.9672 = 1.74 × 10^-4Ea

Ea= 19.122 × 0.9672/1.74 × 10^-4

Ea= 18.495/1.74 × 10^-4

Ea= 1.06 × 10^5 J

Answer:

Carbon monoxide

Explanation:

The molecule has the carbon and oxygen atoms in equal amounts.

Answer:

Atoms and molecules can be deflected by magnetic fields - provided the atom or molecule is first turned into an ion. Electrically charged particles are affected by a magnetic field although electrically neutral ones aren't. The atom or molecule is ionised by knocking one or more electrons off to give a positive ion.

Explanation:

Please Mark me brainliest

The atom must first be ionized.

The mass spectrometer is an important analytical tool in chemistry. It is used to identify atoms and molecules.

However, the atom or molecule to be analysed must first be converted into an ion.

This happens when the instrument imparts an electrical charge to the molecule or atom  then the electrically charged ions are read as electrical current.  The ion is accelerated towards a detector which analyses the deflected ions.

Explanation: We don't see lunar eclipses every cycle because the Moon's orbit is tilted five degrees from Earth's orbit around the Sun. And when an eclipse occurs the earth passes directly between Sun and Moon.

The organism in the bethic zone can survive in such high pressure area. This is because the organism there have no air pockets that provides them the ability to be balanced in the water

Answer:

Heat energy.

Explanation:

The exited electron releases the absorbed energy as heat energy that provides energy to electrons to move from one orbit to another orbit. The electron avails kinetic energy which provides motion in the electron when the energy is absorbed by the electron while on the other hand, electron releases energy which brings the electron into its original orbit. So we can say that the electrons releases energy in the form of heat and come back to its original place.

Answer:

G - the number of eucalyptus trees available

The factor that has the greatest influence on how many koalas live in an area is the number of Eucalyptus trees available. The correct option is G.

The definition of influence as a verb is "to impact or transform someone or something in a manner that is usually significant but not directly immediate." The person or thing that impacts something else also influences that something else.

As they forage, koalas destroy trees and scatter leaves, exposing them to ground insects. Large carnivores in the ecosystem use koalas as prey because they are an essential component of the food chain. Koala conservation equates to maintaining their habitats, which serve as carbon sinks.

Therefore, the correct option is G, the number of Eucalyptus trees available.
