isopentylamine has two n-h peaks while n-butylacetamide has only one n-h peak. why?

Answers

Answer 1

Isopentylamine Hydrochloride. Purity: >98.0%(T). Synonyms: 3-Methylbutan-1-amine

Why it Happens ?

Isopropylamine undergoes the same reactions as other simple alkyl amines, such as protonation, alkylation, acylation, and condensation with carbonyls. Isopropylamine, like other simple aliphatic amines, has a low pKa: [(CH3)2)CHNH3]+ has a pKa of 10.63.

Many herbicides and pesticides, including atrazine, bentazon, glyphosate, imazapyr, ametryne, desmetryn, prometryn, pramitol, dipropetryn, propazine, fenamiphos, and iprodione, include isopropylamine as a building block.It is a plastic regulating agent, an intermediary in the organic synthesis of coating materials, plastics, insecticides, rubber chemicals, medicines, and other chemicals, and an additive in the petroleum sector.

In what region of the electromagnetic spectrum is this line observed?

Answers

The Lyman series is a hydrogen spectral series of transitions and resulting ultraviolet emission lines when an electron moves from n=6 to n = 1 with a frequency of 1.066nm.

Given the electrons are de-excited from n2 = 6 to n1 = 1

From the formula we can observe that, 1/∧ = RZ^2(1/n1^2 - 1/n2^2)

where R is Rydberg’s constant =  109677 cm-1 and Z is atomic number.

Since it is hydrogen atom its atomic number = 1

We know that frequency(f) = c/∧ where 1/∧ = f/c

So, f/c = RZ^2(1/n1^2 - 1/n2^2) where c is speed of

f = 109677 x 10^2 x 1 x (1 - 1/36)

f = 10663041.6 = 1.066nm.

Hence the frequency of the n = 6 line in the lyman series of hydrogen is 1.066nm.

in the early 1960s, radioactive strontium-90 was released during atmospheric testing of nuclear weapons and got into the bones of people alive at the time. if the half-life of strontium-90 is 27 years, what fraction of the strontium-90 absorbed in 1962 remained in people's bones in 1990?

Answers

The fraction of the strontium-90 that remained in people's bones in 1990 can be determined by using the formula:

N(t) = N0 * (1/2)^(t/T)

Where N(t) is the remaining amount of strontium-90 in people's bones at time t, N0 is the initial amount absorbed in 1962, t is the time elapsed (1990 - 1962 = 28 years), and T is the half-life of strontium-90 (27 years).

So, N(1990) = N0 * (1/2)^(28/27) = N0 * (1/2)^1 = N0 * (1/2) = 0.5 * N0

Therefore, the fraction of strontium-90 that remained in people's bones in 1990 is 1/2 or 0.5.

The resultant of the reaction when their change in Enthalpy is positive, change in Entropy is negative and the gibbs free energy is positive is  non spontaneous Reaction. Under the specified conditions, this reaction does not promote the creation of products. A reaction must be endothermic, followed by a reduction in entropy, or both in order to be considered nonspontaneous.

The following are the relationships between spontaneity, entropy, and enthalpy:

Gibbs energy will be negative at all temperatures if enthalpy is negative and entropy is positive.

At low temperatures, Gibbs energy will be negative if enthalpy and entropy are both negative.

At any temperature, Gibbs energy won't be negative while enthalpy is positive and entropy is negative. There wouldn't be an unforeseen response.

Answers

The mass of 6.89 x 10²⁵ molecules of CO₂ will be  approximately 0.5068 kg.

To find the mass in kilograms of 6.89 x 10²⁵ molecules of CO₂, you can use the formula:

mass (kg) = (number of moles) x (molar mass in g/mol) / (1000 g/kg)

First, convert the number of molecules to moles by dividing by Avogadro's number (6.02 x 10²³mol⁻¹) :

6.89 x 10²⁵ CO₂ molecules / 6.02 x 10²³mol⁻¹ = 11.46 x 10² mol

Then, use the molar mass of CO₂ (44.01 g/mol) to find the mass in grams: 11.46 x 10²mol x 44.01 g/mol = 506.8 x 10² g

Finally, convert the mass in grams to kilograms by dividing by 1000 g/kg: 506.8 x 10² g / 1000 g/kg = 0.5068 kg

So, the mass of 6.89 x 10²⁵molecules of CO₂ is approximately 0.5068 kg.

What is the response for a chemical property?

The capacity of a substance to go through a particular chemical transition is described by its chemical property. We search for a chemical change to locate a chemical attribute. Every time there is a chemical transition, one or more new sorts of matter are created that weren't there before.

An electrochemical cell has a positive standard cell potential but a negative cell potential. what must be true of Q and K for the cell? (choose one and please explain why you chose that letter.)
a.) K>1; Q>K
b.) K<1; Q>K
c.) K>1; Q d.) K<1; Q

Answers

If an electrochemical cell has a positive standard cell potential but a negative cell potential K>1; Q>K.

The standard electrode potential is a gauge of the equilibrium potential. The potential of the electrode is the difference in potential between the electrode and the electrolyte. When the concentrations of all the species present in a semi-cell are represented by unity, the electrode potential is referred to as the standard electrode potential.

Given E0 cell is positive and Ecell is negative. Such that from the below equation we can find that Ecell = E0cell - (0.0592/nF)logQ. So, if Q>K then the required conditions are met. These conditions represent a spontaneous redox reaction.

What does the chemical term "reaction" mean?

When atoms establish or break chemical bonds, chemical processes take place. Reactants are the substances that begin a chemical reaction, while products are the compounds that are created as a result of the reaction.

What are fundamental chemical processes?

Combination, decomposition, single-replacement, double-replacement, and combustion are the five fundamental types of chemical reactions. You can classify a reaction into one of these groups by looking at the reactants and products.

Oneway a cell does this is to first put tiny tags on proteins thatare no longer needed. These tags, which are smallpolypeptide chains 76 amino acids long, are calledubiquitin.Ubiquitin tags direct proteins to compartments of the cellcalled proteasomes. Within each proteasome, ubiquitin-tagged proteins are deconstructed into their componentamino acids. These pieces can be repurposed to build newproteins.Sometimes organs stop processing waste effectively,allowing the waste to pile up and contributing to manydiseases. Alzheimer's disease, for example, includes pilesof waste proteins in the brain called tangles, whileParkinson's disease involves the accumulation of recyclablematerial into Lewy bodies. Mallory bodies are piles of wasteproteins common in liver disease. These piles, knowngenerically as inclusions, can be identified under themicroscope because they are covered in tiny ubiquitin tags.A problem in the breakdown of ubiquitin-tagged proteinsmay be one cause of soinocerebellar ataxia tvoe 1.
