Which best describes nuclear fission

2 answers:

7 0

Nuclear fission is either a nuclear reaction or radio active decay process in which nucleus (the center) of an atom splits into smaller parts called nuclei. This is an extremely exothermic reaction (i.e a reaction which produces heat) resulting into release of massive amount of energy in the form of heat and sometimes light. The reaction produces much more energy as compared to a similar mass of a conventional fuel, such as Petrol/Kerosene/Petroleum Gas etc. This makes Nuclear fission an extremely dense and at times very destructive source of energy. Some common elements capable of Nuclear fission are Uranium, Plutonium etc. Though in modern days Nuclear Fission are finding application in being a source of energy (such as a Nuclear power plant), but they are also used in destructive format as Nuclear Bombs and it's one of the top most imminent threats to the existence of humanity in future (in the event of a Nuclear war).

Vlad [161]

The question is incomplete, the complete question is:

Which statements are consistent with Dalton's atomic theory as it was originally stated? Why?

a. Sulfur and oxygen atoms have the same mass.

b. All cobalt atoms are identical.

c. Potassium and chlorine atoms combine in a 1:1 ratio to form potassium chloride.

d. Lead atoms can be converted into gold.

Answer: The correct options are b) and c).

Explanation:

Some of the postulates of Dalton's atomic theory are:

All matter is made of very tiny particles called atoms that participate in chemical reactions
Atoms are indivisible particles that cannot be created or destroyed in a chemical reaction
Atoms of a given element are identical in mass and chemical properties
Atoms of different elements have different masses and chemical properties.
Atoms combine in the ratio of small whole numbers to form compounds.
The relative number and kinds of atoms are constant in a given compound.

For the given options:

For a:

The statement is inconsistent with the theory as no two elements can have the same mass. Only atoms of the same element can have the same mass.

For b:

This is consistent with the theory as atoms of the same element are identical.

For c:

This is consistent with the theory as atoms combine in a simple whole number ratio.

For d:

The statement is inconsistent with the theory as atoms of one element cannot be changed to atoms of other element.

Hence, the correct options are b) and c).

The measurable properties of a substance, such as vapor pressure and surface tension, occur due to the strength of

SpyIntel [72]

Properties of a substance such as vapor pressure and surface tension depend on electrical forces between particles, as given by Coulomb's law.

The vapor pressure refers to how easily a liquid converts to gas while surface tension is the force that makes a liquid surface act as a stretched elastic skin.

Both vapor pressure and surface tension has a lot to do with the degree of polarity in a molecule. Usually, polar molecules have a low vapor pressure and high surface tension due to a high electrical forces between particles, as given by Coulomb's law.

Answer:

An addition reaction

Step-by-step explanation:

In an addition reaction, two or more molecules come together to form a single product, for example,

C₂H₂ + 2Cl₂ ⟶ C₂H₂Cl₄

This reaction consists of two successive additions. The product of the first reaction becomes a reactant and adds a second molecule of Cl₂ to form C₂H₂Cl₄

C₂H₂ + Cl₂ ⟶ C₂H₂Cl₂

C₂H₂Cl₂ + Cl₂ ⟶ C₂H₂Cl₄

C₂H₂ + 2Cl₂ ⟶ C₂H₂Cl₄
