4vir4ik [10]3 years ago
5 0

Molar mass of CHCl3 is

sum of atomic mass of all the atoms in it.

= C + H + 3 Cl

= 12.0107 + 1.008 + 3 (35.453) = 2.0107 + 1.008 +   106.359

= 119.38 g/mol

Molar mass of CHCl3 is 119.38 g/mol

What is the relationship between wavelength and the frequency?
Nutka1998 [239]

Answer:

The wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength

Explanation:

Hope that helps a little

Give a possible explanation for the relative amounts of the isometric methyl nitrobenzoates formed in the nitration reaction. Co
vovikov84 [41]

Answer:

The electrophilic aromatic substitution reaction nitration is used to nitrate methyl benzoate and acetanilide with a nitronium ion. Crystallization was used to purify the product. The melting point was used to determine its purity and the regiochemistry of the products.

Explanation:

Methyl m-Nitrobenzoate is formed in this

reaction rather that ortho/para isomers

because of the ester group of your starting

product of methylbenzoate. The functional

group of ester is a electron withdrawing group

causing nitrobenzene (N02) to become in the

meta position. Thus N02 is a deactivating

group causing itself to be a meta director.

Basically you must look at the substituents

that are attached to your starting benzene ring

in order to figure out whether your reaction

with be ortho/para directors or meta

directors. If the substituents are electron

withdrawing groups then you will be left with

meta as your product but if your substituents

are electron donating groups then your

product will be ortho/para.

Decide whether a chemical reaction happens in either of the following situations. If a reaction does happen, write the chemical
iragen [17]

Answer: The chemical equations are given below.

Explanation:

A balanced chemical reaction follows law of conservation of mass.

This law states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form. This also means that total number of individual atoms on reactant side must be equal to the total number of individual atoms on the product side.  

Single displacement reaction is defined as the reaction in which more reactive metal displaces a less reactive metal from its chemical reaction.

General equation representing single displacement reaction follows:

AB+C\rightarrow CB+A

C is more reactive element than element A.

The reactivity of metals is judged by the series known as reactivity series. Elements lying above in the series are more reactive than the elements lying below in the series.

  • 1. When solid lead metal is put in the beaker of 0.043 M Fe(NO_3)_2 solution.

Lead lies below in the reactivity series than iron. Thus, it will not replace iron from its chemical reaction.

Pb(s)+Fe(NO_3)_2(aq.)\rightarrow \text{No reaction}

  • 2. When solid iron metal is put in the beaker of 0.044 M Pb(NO_3)_2 solution.

Iron lies above in the reactivity series than lead. Thus, it will easily replace lead from its chemical reaction.

Fe(s)+Pb(NO_3)_2(aq.)\rightarrow Fe(NO_3)_2(aq.)+Pb(s)

Hence, the chemical equations are given above.
