The properties of the original elements are completely changed.
For example, in the compound called "iron(II) sulphide", it is composed of iron and sulphur, that are chemically combined together. The element iron is attracted to magnets. Meanwhile, iron(II) sulphide is not attracted to magnets.
Another example is where sulphur has a yellow colour, but iron(II) sulphide has a brownish colour. As we can see, even the physical properties (colours) are completely different.
Therefore, the properties of the original elements are completely changed when they're combined into compounds.
A nucleic acid that carries the genetic information in cells and some viruses,
consisting of two long chains of nucleotides twisted into a double helix and
joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine.
Answer:
Water is important in chemical weathering because most substances dissolve in water.
The process of dissolving breaks up the minerals in the rock into small pieces. The small pieces mix with water to form.
Acids are also agents of chemical weathering and cause more chemical weathering than pure water does.
C- argon
This is because, an electrolyte is a solution that conducts electricity due to the presence of ions, and since argon is an atom and not an ion, it cannot conduct. Thus, it is a non-electrolyte
