You have an atom with a mass number of 100 with 85 neutrons. What is this
element?
Answers
Answer:
phosphorus i believe
Explanation:
in order to find the atomic number you minus the mass number from number of neutrons then just look it up in a periodic table
The mass number of the atom is 100 and number of neutrons is 85. Then, number of protons is 15. Then, element with 15 protons and 15 electrons is phosphorous.
What is mass number ?An atom is composed of subatomic particles electrons, protons and neutrons. Protons and neutrons are located inside the nucleus. The mass number of an atom is sum of number of protons and neutrons.
The number of electrons in an atom in its neutral state is called its atomic number. In a neutral atom, the number of electrons and proton are the same.
Give the mass number = 100
no.of neutrons = 85
no.of protons = 100 -85 =15
no.of electron = 15
Thus, atomic number = 15.
The element with atomic number of 15 is phosphorous (P).

Which of the following are false about Prokaryotic Transcription termination?
A. It can occur in a factor dependent fashion.
B. It can occur in a factor independent fashion.
C. It may involve Rho protein.
D. none of the above.
Answers
Answer: none of the above
Explanation:
In Prokaryotic Transcription termination, it should be noted that the RNA polymerase transcribes through a terminator sequence, which in turn results in the polymerase to be separated from the DNA and thereby leads to its release of the transcrip.
Prokaryotic Transcription termination can occur in a factor dependent fashion, can occur in a factor independent fashion and may involve Rho protein.
Therefore, none of the options is false.

An aluminum cylinder has a radius of 3.2 cm and a length of 8.6 cm. What is the mass of the aluminum cylinder if aluminum has a density of 2.7 g/cm3?
please help :)
Answers
Answer:
750g of Aluminum
Assuming 8.6 cm lenth is the height of the cylinder. The volume of a cylinder is: V = [tex]\pi[/tex]*r^2*h
V = 3.14cm x 10.24cm x 3.6cm
V = 280cm^3
Now density = mass/volume
2.7g/cm^3 = mass/280cm^3
2.7g/cm^3 x 280cm^3 = mass/280cm^3 x 280cm^3
= 750g of Aluminum
11.In 13C NMR spectroscopy, the signal due to this type of carbon occurs furthest downfield.A)–CºNB)C)D)E)–CºC–
Answers
Answer:
C=O
Explanation:
The nuclear magnetic resonance (NMR) spectroscopy is a method that employs the technique to observe the local magnetic fields are atoms. This analytical technique exploits sufficient differences in the frequency of nuclear magnetic resonance in protons and atoms within organic compounds that depend on their neighboring atoms.
Amongst all the given options, the carbonyl is the right option because the carbon is doubly bonded to the oxygen and the hybridization of this double bond is sp² hybridized, as a result, the electron density at the carbon possess a lower amount in order to have more magnetic field.
The increasing order of these chemical shifts are as follows:
C - X < [tex]\mathbf{C -O }[/tex]≅[tex]\mathbf{ \mathrm{-C\equiv C-}}}[/tex] < -C≡N < C=O
what would happen to the solvent if a reaction was refluxed without a condenser
Answers
Answer:
Solvent will be lost as gas and not return into the vessel via condensation.
Explanation:
Reflux is a technique used in chemistry to boil a particular solvent and convert the gas formed back into liquid by condensation. This technique allows a solvent to be heated at a regulated temperature but for a prolonged period of time than it would normally take place.
The reflux procedure makes use of a reflux CONDENSER, which is an apparatus that allows vapour from the heating/boiling to flow back into the reaction vessel. The CONDENSER functions to prevent the loss of the SOLVENT as vapour by providing a cooling effect on the vapour.
Therefore, if a reaction was refluxed without a condenser, THE SOLVENT WILL BE LOST AS VAPOUR

A food sample's caloric value is calculated. By dividing the total weight throughout grams of a particular food by the nutritionists' calculated energy values.
What is calorie?The calorie is an amount of energy that derives from the outmoded caloric concept of heat. Two primary interpretations of "calorie" are frequently used due to historical factors.
The quantity of energy needed to elevate the temperature from one water molecule through one degree Celsius is known as a big calorie, food caloric intake, dietary calorie, simply kilogram calorie. A food sample's caloric value is calculated. By dividing the total weight throughout grams of a particular food by the nutritionists' calculated energy values.

Answers
Complete Question
Which is most reactive toward electrophilic aromatic substitution?
A Phenol
B Anisole
C Nitro-benzene
D Benzene
Answer:
The correct option is A
Explanation:
Generally the rate at which electrophilic aromatic substitution reaction occur is dependent on the nucleophilicity(nucleophile strength ) of Benzene ring.Now a functional group which increase the electron density in the benzene ring when attached to it increases its nucleophilicity and this in-turn will increase the rate at which electrophilic aromatic substitution reaction occur
Now Phenol is a compound that is made up of OH functional group and then the benzene ring
Anisole is a compound that is made up of [tex]OCH_3[/tex] functional group and then the benzene ring
Nitro-benzene is a compound that is made up of [tex]NO_2[/tex] functional group and then the benzene ring
Now since OH is the highest In series of activating group compared to the activation groups we are considering (i.e [tex]OCH_3[/tex] and [tex]NO_2[/tex] )
Then Phenol is the answer

C) w? describes the electronic structure of the atom according to the Bohr model. D) w describes the exact volume of an atom. E) w2 describes the size of an atom.
Answers
Answer:
wdescribes the probability of finding an electron in space.
Explanation:
The quantum mechanical model of the atom assigns wave properties to the electron. This is in accordance with Heisenberg's uncertainty principle.
The probability of finding the electron in a given volume element is given as the square of the wave function while the wave function itself does not really have a physically significant meaning.
However, the wave function is a mathematical function that contains a detailed information about the behavior of an electron.
