Torrey's neighbor told her that a marble rolling down a hill increases in velocity as it rolls down, but does not increase in ki

netic energy because energy can neither be created nor destroyed, so it always has the same amount kinetic energy is Torrey's neighbor correct ? If they are correct, explain how you know . If they are not correct would you explain to them the fault in their thinking ?

Answer:

Torrey's neighbour is incorrect because increase in kinetic energy is proportional to velocity.  If the velocity increases so will the object's kinetic energy.  Because the mass is constant, if the velocity increases, so does the kinetic energy.

Give the coordination number of the central metal ion in the following complex ions.
melomori [17]

Answer:

a). Coordination no. of [Ni(en)_2(NH_3)_2]^2+ = 6

b). Coordination no. of [Fe(en)(ox)Cl_2]^2- = 6

Explanation:

Coordination number is defined as number of donar atoms bonded to the central atom of the complex ion.

a). Coordination no. of [Ni(en)_2(NH_3)_2]^2+ = 6

en or ethylenediamine is a bidentate ligand.

In bidentate ligand, two atoms directly bonded to the central atom.

NH3 is a unidentate ligand.

So, coordination no.= No. of bidentate ligand x 2 + No. of unidentate ligand

                                = 2\times 2 + 2 = 6

b). Coordination no. of [Fe(en)(ox)Cl_2]^2- = 6

Ethylenediamine (en) is a bidentate ligand.

oxalate ion (ox) is also a bidentate ligand.

Cl is a unidentate ligand

So, coordination no.= No. of bidentate ligand x 2 + No. of unidentate ligand

                                = 2\times 2 + 2 = 6

How do you make these equations balanced?
Sedaia [141]

Explanation:

both iron and sulphur in FeS2 undergo a change in oxidation state.

O2° -->2O degree2- Total decrease = 2×2=4

So, 4FeS2+11O2 --> 2Fe2O3+8 SO2

Hence, balanced
