I NEED HELP ASP For the following compounds please determine the correct subscripts: OsaNb RhcCd The subscripts are a b c d

a-1, b-2, c-1, d-1

Explanation:

Let us look at the first compound- OsN2

Since osmium is in +6 oxidation state and nitrogen is in -3 oxidation state. The valency of the species are 6 for osmium and 3 for nitrogen. They can now exchange valencies and we have Os3N6. Reducing to the lowest term we now have OsN2 as the formula of osmium nitride.

Similarly, rhodium is triply bonded to carbon to form the compound RhC in which the rhodium and carbon share six electrons. There is one sigma bond and two pi bonds between the atoms of rhodium and carbon.

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
