What do you notice when you get into a car that has been sitting in the sun for a while?
Alona [7]

Answer:

I notice that it's extremely hot after it has been sitting in thr sun for a while. The sun's rays have been directly shining on the car because the car was in the sun's Ray's directly. If the car's windows were to be left open, it would be less hot but still be hot if the rays of the sun were directly on the car.

Which of these is a pair of coordination isomers (aka ionization isomers)?
vagabundo [1.1K]

Answer:  [Ni(NH_3)_3Br]Cl and [Ni(NH_3)_3Cl]Br are ionization isomers.

[Pt(Cl)_2(SCN)_4]^{4-} and [Pt(Cl)_2(NCS)_4]^{4-} are linkage isomers.

Explanation:

Ionization isomerism occur when a ligand that is bound to the metal center exchanges places with an anion or neutral molecule that was originally outside the coordination complex

Thus [Ni(NH_3)_3Br]Cl and [Ni(NH_3)_3Cl]Br are ionization isomers.

Linkage isomerism is the existence of coordination compounds that have the same composition differing with the connectivity of the metal to a ligand.

Thus [Pt(Cl)_2(SCN)_4]^{4-} and [Pt(Cl)_2(NCS)_4]^{4-} are linkage isomers.

What is the mass of an original 5.60-gram sample of iron-53 that remains unchanged after 25.53 minutes?
olga_2 [115]
Answer is 0.7 g

Reason: Given: mass of Fe = 5.60 gWe know that, half life of Fe-53 = t1/2 (Fe-53) = 8.51 min.
Thus, after 25.53 mins, number of half life passed = 25.53/8.51= 3

Now, Amount left after first half life = 5.60g/2 = 2.80 g
Amount left after second half life = 2.80g/2 = 1.40 g
Amount left after third half-life = 1.40g/2 = 0.7g.
