Endothermic you can see this by putting a thermometer in a glass or warm water, adding an ice cube and watching the temperature go down as the ice melts
A biomolecule with a hydroxyl (--oh) functional group is
given the polar chemical property since organic molecules with an OH group are
polar.
A part of a larger molecule is made up by a functional
group. The hydroxyl group (-OH) that characterizes alcohols, an oxygen with a
hydrogen attached, is an example of it. This group can be found on any number
of different molecules.
Functional groups have characteristic chemistries, just
as elements have unique properties., although perhaps not identically,
to an -OH on another molecule. Although perhaps not
identically to an -OH on another molecule, an -OH group on one molecule will tend to react similarly.
The answer is 12 mL.
When dealing with water, the mass in grams is the same as the volume in milliliters. Thus, if the rain has a mass of 12g, the volume is 12mL.
Answer:
Isocyanates
Explanation:
The functional group is cyanate ion of the formula NCO⁻. The atoms in this functional group occur in a straight line giving it a linear structure. It has a singe C-O bond and a triple N ≡ C bond. It forms cyanate salts when it reacts with pure elements like sodium and other reactive metals as it has some acidic properties. It also forms complexes like silver cyanato [Ag(NCO)₂]⁻
D. It is the heat required to change a gram of substance from a liquid to a gas.
Explanation:
The heat of vaporization is the heat required to change a gram of substance from a liquid to a gas.
- It is also known as the enthalpy of vaporization.
- The heat of vaporization is the quantity of heat needed to change one gram of a substance from liquid to gas.
- This heat of vaporization is dependent on the pressure conditions the process is taking place.
- Different liquids have their heat of vaporization.
