Answer:(1) 6 sodium ions
(2)The movement of iodide ions occurs in the same direction as the sodium ions.
Explanation: Sodium-iodide symporter actively transports 2 sodium ions together with one iodide ions across the basement membrane into the thyroid follicular cells.(therefore for production of a single molecule of T3 3×2=6 sodium ions)This system utilises the concentration of sodium ions so that iodide ions can move against its concentration gradient.
The answer is:
the molarity = 50 moles/liters
The explanation:
when the molarity is = the number of moles / volume per liters.
and when the number of moles =2.5 moles
and the volume per liters = 0.05 L
so by substitution:
the molarity = 2.5moles/0.05L
= 50 moles /L
Answer:
i) Use of wrong Indicator in acid base titration.
ii) Addition of chemicals with improper sequence.
iii) Wrong technique used during chemical reaction.
I think it would be wool fabric, D. Because when you get a piece of wool fabric and rub it against a balloon it creates static electricity. Hope I helped some :)
