Answer:
True.
Explanation:
Iodine is an essential element required for the synthesis of Thyroxine is a correct statement.
Iodine is an essential and controlling medium for thyroid hormone production, as a minor ingredient. It is an important element in the development of thyroid hormones thyroxine (T4) and triiodothyronine (T3) by the thyroid gland.
Answer:
D. Partial pressure
Explanation:
Partial pressure is the individual pressure exerted by each gas present in a gaseous mixture. As he is measuring the pressure of each gas in the atmosphere separately, so PARTIAL PRESSURE is the exact term for his measurement.
Answer:
K = K1×K2 = [CO2] [H2]⁴ / [H₂O]² [CH4]
Explanation:
Based on the reactions:
CH2 (g) + H2O(g) ⇄ CO (g) + 3H2 (g) K1
CO (g) + H2O (g) ⇄ CO2 (g)+H2(g) K2
The sum of both reactions is:
CH4 (g)+2H2O (g) ⇄ CO2(g)+4H2(g) And K of the reaction is: K = K1×K2
K is defined as the ratio between concentrations of products and reactans. Each compound must be elevated to its coefficient in the reaction. That is:
<h3>K = K1×K2 = [CO2] [H2]⁴ / [H₂O]² [CH4]</h3>
