Answer and Explanation:
1. Arrhenius Theory which describes the concept protonic. The substance that gives H+ ions when diluted in water is called as an acid (e.g. HCl) and the substance that dissociates OH-ions whenever it is diluted in water is called as the base (e.g. NaOH)
on the other hand
Bronsted Lowery Theory describes the concept of a proton donor-acceptor. The proton-donating species is an acid and the proton-accepting species is known as a base.
2. The Chemical name and nature of acid is shown below:-
Nature Chemical Name
a. HCl Acidic Hydrochloric Acid
b. KOH Basic Potassium hydroxide
c. HNO Acidic Nitric Acid
d. Mg(OH)2 Basic Magnesium hydroxide
Answer:
NUCLEAR ENERGY -----> MECHANICAL ENERGY -------> THERMAL ENERGY --------> ELECTRICAL ENERGY
Explanation:
In nuclear reactor, various energy transformations occur in order to generate electricity. Nuclear reactor converts the energy released from nuclear fission and the heat generated is removed from the reactor by a cooling system where steam is generated. The steam then drives a turbine which powers a generator to produce electricity.
A nuclear reactor is hence an equipment where nuclear chain reactions occur and control can be obtained. The nuclear reactor uses mostly uranium-235 and Plutonium-239. When these radioactive substances absorbs neutrons, they undergo nuclear fission causing the nucleus to split into two or more smaller compounds with the release of kinetic energy a form of mechanical energy, gamma radiations and others.The kinetic energy is then harnessed in the equipment as heat (thermal energy) which is received by a cooling system and steam is generated. The steam can then power the generator from which electricity is obtained (electrical energy).
So therefore, in a nuclear reactor, the nuclear energy is transformed to mechanical energy and then thermal energy which powers the generation of the electrical energy.
Answer:
The actual number of moles is 9 moles.
It is less than 15
Number of moles needed is 9 moles
Explanation:
15H2 + 10N2 ——-> 10NH3
Now from the question, we can see that the percentage yield is 60%
The percentage yield can be calculated as actual moles of H2/Theoretical moles of H2 * 100%
From the equation, we can see that the theoretical number of moles of hydrogen is 15.
Now to get the actual : 60 = x/15 * 100
x = 9
The actual number of moles is 9 moles.
It is less than 15
Number of moles needed is 9 moles
Answer:
1 electron is involved.
Explanation:
Hello,
In redox reactions, when therer's the necessity to know the involved equivalents, they equal the number of transferred electrons, in this case, since one equivalent is stated, one electron is transferred (involved).
Best regards.
NO, two atom with the same mass number can never be isotope of each other.
This is because for atoms to be considered as isotopes, they must have the same number of protons but different number of neutrons. There is no way two atoms will have the same mass number and their proton number will be the same, this means that two atoms with the same number of mass number can not be isotope of each other.
