Which statement compares the masses of two subatomic particles?(1) The mass of an electron is greater than the mass of a proton.
(2) The mass of an electron is greater than the mass of a neutron.
(3) The mass of a proton is greater than the mass of an electron.
(4) The mass of a proton is greater than the mass of a neutron.
Answers
atoms are made of 3 types of subatomic particles - electrons, protons and neutrons
mass of proton is 1 atomic mass unit and proton is also 1 atomic mass unit
masses of protons and neutrons are very similar
mass of an electron is 1/1840th of 1 atomic mass unit
mass of electron is insignificant when compared to masses of neutrons and protons
protons and neutrons have a larger mass than electrons
from the given options correct answer is
(3) The mass of a proton is greater than the mass of an electron
Protons have mass 1
Neutrons have mass 1
(1) 0 is not greater than 1
(2) 0 is not greater than 1
(3) 1 is greater than 0
(4) 1 is not greater than 1
So the answer is (3) The mass of a proton is greater than the mass of an electron

The Arrhenius theory established that acids and some bases: dissociate giving rise to ions.
What is the Arrhenius theory?
Arrhenius's theory was a theory of acids and bases formulated on the basis of his theory of ionization of substances in aqueous solutions.
Principles of the Arrhenius theory
- Acid substances are those that dissociate into hydrogen ions in aqueous solution.
- Basic substances are those that dissociate into hydroxyl ions in aqueous solution.
Therefore, we can conclude that the Arrhenius theory explains that the characteristic properties of aqueous solutions of acids are due to hydrogen ions.

Answer:
According to the theory, an Arrhenius acid is a substance that gives hydrogen ion, (or protons) as the only positively charged ions, when dissociated in water.
Explanation:
What this means is that acids increase the concentration of protons in water to form hydronium ions,as opposed to the idea that there aren't free hydrogen cations floating around in aqueous solution.
The Arrhenius definitions of acidity and alkalinity are restricted to aqueous solutions and refer to the concentration of dissolved ions.

d. mutation rate
Answers
Answer;
Mutation rate
-Mutation rate is not a difference between a population showing exponential growth and a population showing logistic growth.
Explanation;
-When the resources are unlimited, populations exhibit exponential growth, resulting in a J-shaped curve and when the resources are limited, populations exhibit logistic growth.
-The carrying capacity is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment. It affects the size of population and thus has an effect on both exponential and logistic growth.
-Food limits and disease limits are also other factors that may determine the population size in a biological ecosystem.

Answer: Neutrons released act as reactants in next reaction.
Explanation:
Nuclear chain reactions occur in fission reactions only. Nuclear fission reactions are defined as the reactions in which larger nuclide splits into two or more smaller daughter nuclides.
In nuclear chain reaction, the neutrons that are released in the previous fission reaction act as the starting material in the next reaction. Thus, this process continues to many reactions and hence, is known as nuclear chain reaction.
For Example: Uranium-235 on bombardment of 1 neutron undergoes fission reaction producing 3 neutrons and a huge amount of energy. The reaction follows:
Hence, neutrons released act as reactants in next reaction.
