Final answer:
The difference between covalent bonds and ionic bonds is b. Covalent bonds involve the sharing of electrons between atoms; ionic bonds involve the electrical attraction between atoms.
Final answer:
In covalent bonds, atoms share pairs of electrons to achieve a stable electron configuration. This sharing creates a strong bond between the atoms, and they are typically nonmetals. In ionic bonds, there is a transfer of electrons from one atom to another, resulting in the formation of ions with opposite charges.
One atom becomes positively charged (cation), and the other becomes negatively charged (anion). The electrical attraction between these oppositely charged ions holds them together, forming an ionic bond. Ionic bonds typically form between a metal and a nonmetal.

b. cannot be broken down further.
c. are all composed of carbon.
d. have no mass.
Answer:
B
Explanation:
Atoms are those particles which cannot be broken down further. But, later on the subatomic particles were discovered
John Dalton's Atomic Theory states that atoms are indivisible and cannot be broken down further. They combine to form molecules and are not all composed of carbon. Atoms do have mass.
John Dalton, an English chemist, is famous for his theory of atomic structure, also known as Dalton's Atomic Theory. According to this theory, atoms are the tiniest particles of matter which cannot be divided or broken down further into simpler substances by chemical means. Thus, the correct answer to the question would be (b) - atoms cannot be broken down further.
Atoms can combine in various proportions to form molecules, but they themselves do not contain molecules. Also, not all atoms are composed of carbon, there are many other elements such as hydrogen, oxygen, nitrogen, to name a few. Finally, atoms do possess mass, it is one of their fundamental properties.

The systematic name for the coordination compound [Cr(H2O)4Cl2]ClO3 is tetraaquadichlorochromium(III) chlorate.
The coordination compound you want to name falls under the subject of Chemistry, specifically inorganic Chemistry. The compound is [Cr(H2O)4Cl2]ClO3. The systematic name for this compounds is tetraaquadichlorochromium(III) chlorate. This nomenclature follows rules set out by Alfred Werner where the metal is specified (chromium), the number and type of ligands or ions the metal is bonded to are defined (tetraaqua, which indicates four water molecules, and dichloro for two chlorine ligands), and the oxidation state of the metal is given (III). Finally, the counter ion is named (chlorate).

resources.
Technology is built to give means, tools, and machinery for the preservation of the environment's resources from the damaging effects of climate change and global warming, and the environment in turn provides the materials, which is how technology and the environment are interdependent.
The gradual increase in the planet's surface temperature is known as global warming. Although this warming trend has been around for a while, the burning of fossil fuels has greatly accelerated its pace over the past century. The amount of fossil fuels burned has increased along with the size of the human population.
The two main ways that these technologies have harmed our planet are through pollution and the depletion of natural resources. When dangerous or excessive levels of gases like carbon dioxide, carbon monoxide, sulfur dioxide, nitric oxide, and methane are released into the earth's atmosphere, air pollution results.
Technology and society have a reciprocal interaction. Technological advancement shapes society, while technological advancement drives it.
Thus, the environment's resources from the damaging effects of climate change and global warming, and the environment in turn provides the materials.
