Answer:

Explanation:

Shifting, labor intensive and monoculture are different in terms of description,restrictions and problem.

Shifting is an agriculture method in which an area if land is cultivated for a while and abandoned for the soil to regain and preserve it's fertility. It is done to restore soul fertility.

It has restrictions because it is done in places where there is large areas of land, if there is not large area of land, it will be done.

It can lead to defforestation because trees are cut fine for land cultivation and after a while the land is abandoned and trees are cut down some where else too.

Labor intensive refers to agricultural industry requiring or needing large amount of labor to produce agricultural products. Labor intensive is restricted to areas where there is low or no people who can engage in agricultural services.

Labor intensive require high skilled people which might not be available.

Monoculture is a farming system where by a single crop is cultivated in an area of land.

The problem of monoculture is that it displaces species and nutrients occuring naturally in an ecosystem.

Monoculture is restricted in areas where diversity of crops are needed.

Formula New Combination Predicted Formula
creativ13 [48]
Answer:

<span>Formula      New Combination                     Predicted Formula
</span>

NaCl            potassium + chlorine                KCl


AlCl₃             aluminum + fluorine                AlF₃

CO₂              tin + oxygen                              SnO₂

MgCl₂           calcium + bromine                   CaBr₂

HCl               cesium + iodine                       CsI


<span> CCl₄              silicon + bromine                     SiBr₄</span>

Explanation:

1) The question is incomplete. The first part is missing.

This is the first part of the question.

<span>Applying the principle that the elements of a particular column in the Periodic Table share the same chemical properties, complete the following chart. The first one has been done for you.
</span>

2) This is the given chart:

<span>Formula      New Combination                     Predicted Formula
</span>

Cu₂O           silver + oxygen                          Ag₂O   ← this is the example.

NaCl            potassium + chlorine 

<span> AlCl₃             aluminum + fluorine </span>

CO₂              tin + oxygen 

<span> MgCl₂           calcium + bromine </span>

<span> HCl               cesium + iodine </span>

<span> CCl₄              silicon + bromine </span>


3) This is how you find the new formula to complete the chart.

i) NaCl            potassium + chlorine 

Since potassium is in the same group of sodium, you predict that in the new formula Na is replaced by K giving KCl.

ii) AlCl₃             aluminum + fluorine 

Since fluorine is in the same group that Al, then you predict that in the new formula Cl is replaced by F leading to AlF₃

iii) CO₂              tin + oxygen 

Since tin is in the same group that C, you predict that in the new formula C is replaced by Sn leading to SnO₂

iv) MgCl₂           calcium + bromine 

Since calcium is in the same group that Mg, and bromine is in the same group that Cl, you predict thea in the new formula calcium replaces Mg and bromine replaces Cl, leading to CaBr₂

v) HCl               cesium + iodine 

Since H is in the same column that cesium and Cl is in the same colum that iodine, you predict that in the new formula Cs replaces H and I replaces Cl leading to: CsI


<span> vi) CCl₄              silicon + bromine
</span>

Since silicon is in the same column that C and bromine is in the same column that Cl, you predict that in the new formula Si replaces C and Br replaces Cl, leading to SiBr₄

what Is the number of photons in one J of red light (650 nm) greater than, equal to, or less than the number of photons in one J
valentinak56 [21]
For the same amount of energy, the number of photons in red light will be greater than the number of photons in blue light.
This is because the energy carried by a photon is inversely proportional to the wavelength of the photon. A longer wavelength means there is a lower energy in the photons and a shorter wavelength means that there is a higher energy. Therefore, in order for the photons to deliver one joule of energy, more of the red light photons will be required.
