Why does the mixture of Fe and S have different reactions than the compound FeS?
mario62 [17]

Answer:

fe+s is a mixture of iron and sulphur and it can be separated by magnetic separation. But FeS is a compound formed by heating iron and sulphur together.it can't be separated by any method.

Here are some of the differences between a mixture of iron and sulfur, and iron sulfide: the mixture can contain more or less iron, but iron sulfide always contains equal amounts of iron and sulfur. the iron and sulfur atoms are not joined together in the mixture, but they are joined together in iron sulfide.

Which of the following statements is TRUE? Which of the following statements is TRUE? Two electrons in the same orbital can have
Monica [59]

An orbital that penetrates into the region occupied by core electrons is less shielded from nuclear charge than an orbital that does not penetrate and therefore has a lower energy.

Explanation:

The only true statement from the given options is that "an orbital that penetrates into the region occupied by core electrons is less shielded from nuclear charge than an orbital that does not penetrate and therefore has a lower energy." Inner orbitals which are also known to contain core electrons feels the bulk of the nuclear pull on them compared to the outermost orbitals containing the valence electrons.

  • The nuclear pull is the effect of the nucleus pulling and attracting the electrons in orbitals.
  • This pull is stronger for inner orbitals and weak on the outer ones.
  • The outer orbitals are said to be well shielded from the pull of the nuclear charge.
  • Also, based on the quantum theory, electrons in the outer orbitals have higher energies because they occupy orbitals at having higher energy value.

Nezavi [6.7K]

Answer:

The first claim is false. Natural resources can most definitely exist without synthetic products.

Explanation:

All synthetic products are derived from natural resources as everything has to come from a source in the beginning. However, most natural resources themselves are the source, make sense? For example, water is a naturally occurring resource, but even water is derived from specific components, however it doesn't need anything synthetic to exist. Now take hairspray, to make hairspray you need water and synthetic resources, see where I'm going with that?
