Answer:
5)HOCH2CH2OH
Explanation:
This is also known as ethylene glycol. An increase in hydrogen bonds of a compound means an increase in the viscosity. Hydrogen bonds occur as a result of bonding with electronegative elements such as Oxygen, Nitrogen etc.
The compounds with the highest amount of Hydrogen bond represents the one with the highest viscosity which is B) HOCH2CH2OH
Answer:
Iodine is a mineral found in some foods. The body must have iodine to make thyroid hormones. The hormones control the body's metabolism and many other important functions. Without iodine, thyroid hormone production can decrease.
Explanation:
Answer is: color.
Chemical reaction of dissociation of sodium chloride in water:
NaCl(aq) → Na⁺(aq) + Cl⁻(aq).
Small quantities of water are colorless, solution of sodium chloride is also colorless.
Adding sodium chloride to water change water melting and boiling points.
The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.
The mass numbers of the different isotopes of that element are averaged according to their respective abundances in nature.
