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.

<u>Answer: </u>The correct options are b) and c).

<u>Explanation:</u>

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:

<u>For a:</u>

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.

  • <u>For b:</u>

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

  • <u>For c: </u>

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

  • <u>For d:</u>

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).

Which of the following elements has the strongest ionization energy: Mg or Cl? Define ionization
Mila [183]

Answer:

Cl

Explanation:

The element Cl will have the strongest ionization energy from the given choices. Most non-metals have higher ionization energy compared to metals.

Ionization energy is the energy required to remove the most loosely held electron from the gaseous phase of an atom.

  • As you go from left to right on the periodic table, it increases progressive
  • From top to bottom, the ionization energy reduces significantly.
  • The attractive force between the protons in the nucleus and the electrons plays a very important role.
  • In metals, they have very large atomic radius, the attractive force on the outer electrons is very weak.
  • This is not the case in non-metals

Which of the following correctly describes one way that photosynthetic plants are involved in the carbon cycle? Choose 1 answer:
brilliants [131]

Answer:

The correct answer is - (Choice A) A Photosynthetic plants can move carbon from the atmosphere into an ecosystem’s food web.

Explanation:

Photosynthesis is the process performed by photosynthetic or green plants in presence of light atmospheric carbon dioxide and water converted into glucose (6 carbon compound) and oxygen.

This glucose or sugar is utilized by the plants that are producers in the ecosystem food web. These producers are fed by consumers and carbon molecules transfer from all the trophic levels in the food chain or food web in the process.
