In 1808, John Dalton proposed a series of statements regarding the atom that became known as Dalton's postulates or Dalton's ato

mic theory. Since Dalton's original proposal, some of the statements have been updated or changed due to new discoveries. Which of the statements was not a part of Dalton's original atomic theory? 1) Different elements have atoms of different masses and properties. 2) All four statements are part of Dalton's original atomic theory. 3) Matter is comprised of small particles called atoms. 4) Atoms cannot be created or destroyed in a chemical reaction. 5) Atoms of the same element have the same size, mass, and structure.

Answer:

2) All four statements are part of Dalton's original atomic theory.

Explanation:

The postulates of the Dalton’s atomic theory are:

  • The matter is comprised of small units which are known as atoms.
  • The atoms are indivisible which means that they can not be further divided.
  • Atoms of the matter can neither be created nor be destroyed in the chemical reaction.  
  • All atoms of the particular element are identical.
  • The atoms of the different elements vary in the size and the mass. and posses different properties.
  • The compounds are formed by the different whole number combinations of the atoms.

<u>Hence, all 4 are correct.</u>

2. second one is False  because carbon-carbon bonds are not weak bonds they form mutual covalent bonds which are stronger bonds and cannot be easily disrupted .

3. A single carbon atom has the valency of 4 so it can be bonded with four hydrogen atom at the same time .

do you think that religion and science are in conflict ,or that people can both have both without any problems
natka813 [3]
Religion and science are fundamentally incompatible. They disagree profoundly on how we obtain knowledge of the world. Science is based observation and reasoning from observation. Religion assumes that human beings can access a deeper level of information that is not available by either observation or reason.

Ne4ueva [31]

Answer,

For example, silver ion can be precipitated with hydrochloric acid to yield solid silver chloride. Because many cations will not react with hydrochloric acid in this way, this simple reaction can be used to separate ions that form insoluble chlorides from those that do not.
