Answer:
Yes. These chemicals named barium chloride and calcium carbonate have been named properly. But silicon oxide has not been named correctly, an oxide of silicon is named as silicon dioxide not silicon oxide.
Explanation:
In chemistry while naming chemicals there are certain rules and naming the chemicals as per these rules is known as chemical nomenclature. The IUPAC's rule for chemical nomenclature of inorganic compounds can be read in a book named as red book.
<u>By sign convention, a cation is named first followed by an anion.</u> For example, in barium chloride (BaCl₂), barium which is represented by symbol Ba²⁺ is a cation and therefore written before chloride (Cl⁻) which is an anion. Similarly calcium carbonate is represented as CaCO₃.
As per the valency of silicon, it forms a dioxide with oxygen atom and it is represented as SiO₂.
Answer:
a chemical reaction or other process in which the products themselves promote or spread the reaction, which under certain conditions may accelerate dramatically.
Explanation:
the self-sustaining fission reaction spread by neutrons which occurs in nuclear reactors and bombs.
a series of events, each caused by the previous one.

Hello there!
Electronegativity is the atom's tendency to attract electrons in a chemical bond
There are two trends to electronegativity:
- Electronegativity increases from bottom to top in a group (Li has a greater electronegativity than Fr, for example)
- Electronegativity increases from left to right across a period (the further right the group, the greater the electronegativity)
Looking at a period table, Sb, Sn, Te, and I are all in the same period, so we'll need to decide which element has the highest electronegativity based on the group.
- Sn belongs to group 4A (group 14)
- Sb belongs to group 5A (group 15)
- Te belongs to group 6A (group 16)
- I belongs to group 7A (group 17)
As I belongs to group 7A, the group that is the farthest right based off of the options given, I has the highest electronegativity
Hope this helps!
