Diffusion is the process of a substance spreading out to evenly fill its container or environment. Kinetic energy of particles of matter increases with an increase in temperature. More the kinetic energy in the particles, more is the rate of diffusion. so diffusion is faster in the summer!

hope this helps!

Korolek [52]

Given :

Some compounds :

A)\ CH_3Cl\ B)\ CH_3I\ C)\ CH_3Br\ D)\ CH_4 .

To Find :

Which of the following compounds has the most deshielded protons .

Solution :

Deshielded means nucleus whose chemical shift has been increased due to removal of electron density, magnetic induction, or other effects .

In simple words deshielding means the ability to shift protons .

Now , among Cl , I , Br and H . Cl is the most electron negative .

Therefore , deshielding will be more in CH_3Cl .

Hence , this is the required solution .

How many moles (of molecules or formula units) are in each sample?
Alexus [3.1K]

The number of moles in each sample will be 0.391 moles, 30.7 moles, 0.456 moles, and 1350 moles

<h3>What is the number of moles?</h3>

The number of moles of a substance is the ratio of the mass of the substance to the molar mass.

In other words; mole = mass/molar mass.

Thus:

  • moles of 18.0 g NO_2 = 18.0/46

                                   = 0.391 moles

  • moles of 1.35 kg CO_2 = 1350/44

                                         = 30.7 moles

  • moles of 46.1 g KNO_3 = 46.1/101.1

                                          = 0.456 moles

  • moles of 191.8 kg Na_2SO_4 = 191800/142

                                                 = 1350 moles

How does the location of mesosaurus fossils support the theory of continental drifts?<br>​
Ratling [72]

Answer:

For this reason, the existence of Mesosaurus helps support the theory of continental drift; that is, the now-well-attested fact that South America and Africa were joined together into the giant continent Gondwana 300 million years ago before the continental plates supporting them broke apart and drifted.
