<span>Moles of KIO3 = 0.2164/214.1 = 0.00101 (3 s.f.)
Moles of Na2S203 = 0.00101 x 6 = 0.00606 (3 s.f.)
Concentration of Na2S203 = 0.00606/6.20 = 0.000977 (3 s.f.) (I use mol/dm-3 instead of mol/L so i don't think it's converted to mol/L from mL) hope this helps</span>
One of the ways to minimize a collision is to slow down: When you can't find an escape and you're definitely going to collide with something, you should slow your vehicle down as much as possible.
Hope this helps ^^
Answer:
B. bromelain
Explanation:
Pineapple also contains a digestive enzyme called bromelain, which is a mixture of proteolytic enzymes and has been chemically known since 1876 (Taussig and Batkin, 1988).
Helloooooooooooooooooooooo
Answer:
Ni^2+ is most likely
Ti^3+ is very unlikely
Explanation:
The Crystal Field Stabilization Energy almost always favors octahedral over tetrahedral in very many cases, but the degree of this favorability varies with the electronic configuration. In other words, for d1 there is only a small gap between the octahedral and tetrahedral lines, whereas at d3 and d8 is a very big gap. However, for d0, d5 high spin and d10, there is no crystal field stabilization energy difference between octahedral and tetrahedral. The ordering of favorability of octahedral over tetrahedral is:
d3, d8 > d4, d9> d2, d7 > d1, d6 > d0, d5, d10. This explains the answer choices above.
Ti^3+ being a d1 specie is least likely to exist in octahedral shape while Ni2+ a d8 specie is more likely to exist in octahedral shape.
