The moles of silver nitrate required to form 0.854 mol silver ion has been 0.854 mol.

The balanced chemical equation for the dissolution of silver nitrate has been:

[tex]\rm AgNO_3\;\rightarrow\;Ag^+\;+\;NO_3^-[/tex]

The aqueous solution of silver nitrate has been dissociated into the constituent silver and nitrate ions.

In a balanced chemical equation, the coefficient has been equivalent to the moles of each reactant forming the moles of product.

From, the balanced equation,

[tex]\rm 1\;mol\;AgNO_3=1\;mol\;Ag[/tex]

The given moles of Silver has been 0.854 mol. Thus, the moles of silver nitrate required has been given as:

[tex]\rm 1\;mol\;Ag^+=1\;mol\;AgNO_3\\0.854\;mol\;Ag^+=0.854\;\times\;1\;mol\;AgNO_3\\0.854\;mol\;Ag^+=0.854\;mol\;AgNO_3[/tex]

The moles of silver nitrate required to form 0.854 mol silver ion has been 0.854 mol.

The compound that contains both sigma and pi bonds has been [tex]\rm \bold{H_2CO}[/tex]. Thus, option B is correct.

The compounds have been resulted by the sharing of the valence electrons between atoms, for the completion of octet of each elements.

The bonds can be saturated with the presence of only sigma bond. The unsaturated bonds has presence of pi bonds as well. The bond with one pi and one sigma has been a double bond, while 1 sigma and 2 pi has been a triple bond.

The bonds present in the following structures has been:

[tex]\rm HCCl_3=4\;\sigma\;bonds\\H_2CO=2\;\sigma,\;1\;\pi\;bond\\H_2S=2\;\sigma\;bonds\\HBr\;=1\;\sigma\;bond[/tex]

The compound with the presence of both sigma and pi bonds has been [tex]\rm \bold{H_2CO}[/tex]. Thus, option B is correct.

Explanation:

The neutral atom is isoelectronic with N⁻³ is Neon (Ne).

Isoelectronic are those which have same number of electrons or we can say that same electronic structure.

For finding out that the species are isoelectronic , we just have to count there no. of electrons of atoms and if they have same no. of electron then they said to be isoelectronic species.

no. of electrons in Nitrogen N = 7 ( atomic no.)

no. of electrons in Nitride ion N⁻³ = 7 + 3 = 10

no. of electrons in Neon Ne = 10 ( atomic no. and neutral atom)

so, no. of electrons in Nitride ion N⁻³  = no. of electron in Neon Ne

this means , N⁻³ , Nitride ion is isoelectronic with Neon Ne.

Thus, The neutral atom is isoelectronic with N⁻³ is Neon (Ne).

Answer:

Answer:

Higher pitched sounds produce waves which are closer together than for lower pitched sounds. (Think of the slinky - if you produce waves rapidly they will travel quite close to each other, thus demonstrating a higher pitched sound.)

The pitch of a note will depend on a number of factors. One of these is the size of the vibrating object. On a glockenspiel or xylophone the high notes are made by the smaller bars. A smaller triangle or cymbal will make a relatively higher pitch note. On a stringed instrument such as a guitar or violin a thinner string will generally make a higher note, but also shortening the string by stopping it with the finger will produce a similar effect. On a set of pan pipes or a church organ it is the shorter pipes which make the higher notes when the air inside them vibrates.

Another factor which produces higher pitched notes is the tension within the vibrating object. A guitar string can be tuned to a higher pitch by adjusting the string tensioner. An elastic band can be stretched tighter and a drum skin can be tensioned to increase the pitch of the sound it produces.

a hypothesis is a prediction based on a theory. If the Hypothesis comes true the theory is more accepted.

A scientific theory differs from a scientific fact or scientific law in that a theory explains "why" or "how": a fact is a simple, basic observation, whereas a law is a statement (often a mathematical equation) about a relationship between facts.
