Comparing the two waves, wave B has a...

A) higher frequency.
B) greater amplitude.
C) shorter wavelength.
D) longer wavelength.

Answers

Answer: D) longer wavelength.

Explanation:

A) higher frequency and C) a shorter wavelength.

As far as I know, you calculate frequency on a graph using the number of peaks you can see. Since the wavelength is shorter (the distance between two peaks on the wave), the frequency should also be higher as more fit on the graph.

There are six main components, or parts, of weather. They are temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness. Together, these components describe the weather at any given time.

Chemical Weathering Rocks are changed by chemical and physical weathering. During chemical weathering, the composition of the rock is changed. Extreme heat and pressure within Earth can also cause rocks to change chemically. Physical weathering is the breaking down of rock by wind, water, ice, temperature change, and plants. It changes the shape and size of rocks, but it does not change their properties.

What is Chemical Weathering ?

Chemical Weathering can be described as the type of weathering that do take place due to the breaking down of the rock particles into smaller pieces which is usually as a result of chemical process.

It should be noted that when the process is taking place it scould be due to the Extreme heat and pressure which can affect the composition of the particles and as a result of this there could be formation of products from the break down.

How do acidic character vary among the trihalides of Boron? Give reason in support of your answer.
Kinda confused, give any 5 points in support of your answer. :D

#BeBrainly

Answers

Answer:

Explanation:

All three lighter boron trihalides, BX3 (X = F, Cl, Br), form stable adducts with common Lewis bases. Their relative Lewis acidities can be evaluated in terms of the relative exothermicities of the adduct-forming reaction. Such measurements have revealed the following sequence for the Lewis acidity: BF3 < BCl3 < BBr3 (in other words, BBr3 is the strongest Lewis acid).

This trend is commonly attributed to the degree of π-bonding in the planar boron trihalide that would be lost upon pyramidalization (the conversion of the trigonal planar geometry to a tetrahedral one) of the BX3 molecule, which follows this trend: BF3 > BCl3 > BBr3 (that is, BBr3 is the most easily pyramidalized). The criteria for evaluating the relative strength of π-bonding are not clear, however. One suggestion is that the F atom is small compared to the larger Cl and Br atoms, and the lone pair electron in the 2pzorbital of F is readily and easily donated, and overlaps with the empty 2pz orbital of boron. As a result, the [latex]\pi[/latex] donation of F is greater than that of Cl or Br. In an alternative explanation, the low Lewis acidity for BF3 is attributed to the relative weakness of the bond in the adducts F3B-L.

Answer:

The Lewis acidity of BF3, BF2Cl, BFCl2, and BCl3 in acid−base orbital interactions has been studied. We have derived the unoccupied reactive orbitals that show the maximum localization on the boron pπ atomic orbital overlapping with the lone-pair orbital of an electron donor and have evaluated the electrophilicity of the boron center in these compounds. The Lewis acidity of boron is shown to be controlled by two factors: localizability of the unoccupied reactive orbital on the boron pπ atomic orbital and the polarizability of the boron center. The former has been shown to be similar in magnitude in these boron halide compounds. Contrary to common belief, the conjugation between the boron atom and the attached halogen atoms is not necessarily stronger in BF3 relative to others. The trend observed in experiments and in theoretical calculations for BF3, BF2Cl, BFCl2, and BCl3 is interpreted in terms of these factors.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.

Answers

Answer:

No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

No it would not conduct electricity as it is a insulator
