Peter Parker is 28 years old in the 616 Marvel Universe. This answer is subject to change, as writers may adapt the age through their stories. Peter's age is somewhat fluid, aging in real time at some points, while almost not aging at all for some periods.
Answer:
Acid-Catalyzed Ester Hydrolysis
Explanation:
Fischer Esterification is a reversible reaction and the Le Châteliers principle can be used for the reaction to be completed. For the reverse reaction of Fischer Esterification, using the hydrolysis of ethyl ethanoate, the steps involved are:
1) An hydrogen ion is added to the ester and one of the lone pairs on the oxygen double-bonded to the carbon atom takes the hydrogen ion.
2) The lone pairs on the oxygen of a water molecule takes the positive charge on the carbon atom.
3) The hydrogen ion is transferred from one oxygen atom to another.
4) Then an ethanol molecule is released (one of the products).
5) Reaction with a water molecule releases hydrogen from the oxygen and the other product (ethanoic acid) is formed.
Explanation :
Isotope : It is defined as the element that have the same number of protons but have the different number of neutrons of each of the atom.
Atomic number is defined as the number of protons or number of electrons.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and number of neutrons.
Number of neutrons = Mass number - Number of protons
For the given options:
(a)
Atomic number = 5
Number of proton = 5
Number of electron = 5
Atomic mass = 10
Number of neutrons = Atomic number - Number of protons
Number of neutrons = 10 - 5 = 5
(b)
Atomic number = 80
Number of proton = 80
Number of electron = 80
Atomic mass = 199
Number of neutrons = Atomic number - Number of protons
Number of neutrons = 199 - 80 = 119
(c)
Atomic number = 29
Number of proton = 29
Number of electron = 29
Atomic mass = 63
Number of neutrons = Atomic number - Number of protons
Number of neutrons = 63 - 29 = 34
(d)
Atomic number = 6
Number of proton = 6
Number of electron = 6
Atomic mass = 13
Number of neutrons = Atomic number - Number of protons
Number of neutrons = 13 - 6 = 7
(e)
Atomic number = 34
Number of proton = 34
Number of electron = 34
Atomic mass = 77
Number of neutrons = Atomic number - Number of protons
Number of neutrons = 77 - 34 = 43
The answer is D I believe
The reaction between sulfuric acid, H2SO4 , and the base sodium hydroxide, NaOH , is a neutralization reaction. Na2SO4 is the salt sodium sulfate. ... For example, the reaction you've chosen is an acid-base reaction (also known as a neutralization reaction).
