Which statement is part of the kinetic molecular theory? A. Gas particles are in constant motion. B. Gas particles attract each other. C. Gas particles lose their energy during collisions. D. Gas particles stick to the walls of their container.
Answers
Answer:
The answer to your question is: letter A
Explanation:
A. Gas particles are in constant motion. This statement is true because this theory says that Gases are composed of a large number of particles that behave like hard, spherical objects in a state of constant, random motion.
B. Gas particles attract each other. This statement is false because this theory says that there is no force of attraction between gas particles or between the particles and the walls of the container.
C. Gas particles lose their energy during collisions. This statement is false, this theory says that none of the energy of a gas particle is lost when it collides with another particle or with the walls of the container.
D. Gas particles stick to the walls of their container. This statement is false, the theory says that there is no force of attraction between gas particles or between the particles and the walls of the container.

The major reason for the decline in amphibian species is climate change.
Amphibians are organisms that can live on land and in water. They are
usually found around moist areas because they need water bodies to cool
off in order for their survival.
Climate change is characterized by an increase in temperature which
doesn't favor them as they lose more water which thereby threatens survival
and leads to their decline in the ecosystem.

Explanation:
B._25 grams
C._50 grams
D._100 grams
Answers
Answer : The correct option is, (C) 50 grams
Solution :
Formula used :
where,
a = amount of reactant left after n-half lives = ?
= Initial amount of the reactant = 100 g
n = number of half lives = 1
Putting values in above equation, we get:
Therefore, the amount of uranium-238 remain will be, 50 g
This is because a half life is the time it takes for a sample of an unstable isotope to spontaneously so that half of the original sample remains
2. ionic, because the valance electrons are mobile
3. metallic, because the valance electrons are stationary
4. metallic, because the valance electrons are mobile
Answers
A solid substance is an excellent conductor of electricity. the chemical bonds in this substances are most likely metallic, because the valance electrons are mobile. Therefore the correct option is option D.
What is metallic bonding?
Metallic bonding is a type of chemical bonding that rises from the electrostatic attractive force between conduction electrons and positively charged metal ions.
If a solid substance is able to conduct electricity then the chemical bond in the substance will definitely be metallic bond. The reason for excellent conductor of electricity is the mobility of the valence electrons. In metallic bonds valence electrons are mobile.
Therefore the correct option is option D that is metallic, because the valance electrons are mobile.

Answer;
-4. metallic, because the valance electrons are mobile
Explanation;
-Electrical conductivity in metals is a result of the movement of electrically charged particles.The atoms of metal elements are characterized by the presence of valence electrons (electrons in the outer shell of an atom) that are free to move about.
-Therefore; Metallic elements such as sodium and potassium conducts electricity in solid form due to the presence of delocalized valence electrons. These electrons can move freely within the structure of a metal when an electric current is applied.

Final answer:
An atom is electrically neutral when it has an equivalent number of protons and electrons. Therefore, an atom with 35 protons in the nucleus will also have 35 electrons orbiting the nucleus.
Explanation:
In atomic theory, an atom is neutral when the number of protons present in the nucleus is equal to the number of electrons orbiting the nucleus. For example, hydrogen atoms all have one proton in the nucleus and one electron orbiting the nucleus. Therefore, if an atom has 35 protons in the nucleus, it will also have 35 electrons orbiting the nucleus. This is due to the characteristic of atomic structure that aims for neutrality by maintaining an equal number of positive protons and negative electrons.
