Tantalum (Ta), Osmium (Os) and Rhodium (Rh) are metals.
<u>Explanation</u>:
- Metals are good conductors of heat and electricity and they can be hammered into sheets (malleable).Mainly most of them are solids. Ta, Os and Rh are all metals with a same platinum group.
- Tantalum (Ta) with a atomic number 73 is a lustrous transition metal which is highly corrosive resistant. It is mainly used in making electronic equipment.
- Rhodium (Rh) is a chemical element with atomic number 45 is a rare, silvery white,hard and corrosive resistant metal. Osmium (Os) with a atomic number 76 is a hard, brittle bluish-white transition metal.

Answer:
These reagents are also called as reductants. Redox reactions: Reactions which involve change in oxidation number of the interacting species. Problem 8.4 Justify that the reaction: 2Cu2O(s) + Cu2S(s) → 6Cu(s) + SO2(g) is a redox reaction.
It is the second option! the square with more orange dots will have to move over so that there is an equal amount or equilibrium! another way to look at it is, if we just moved the one dot on the left side then that side would be empty and there would not be equilibrium
This isn't a full question!
