Answer: Transpiration---A
Explanation: Transpiration is the process in the water cycle whereby plant loose(excess) water by evaporation through the stomata of their leaves since not all water absorbed by the root is actually used for growth in plants.In order to allow the intake of carbon-dioxide, water must exit the leaves through transpiration which then provides the plant with cooling, rigidity and maintaining the overall water balance of the plant.
Answer:
London Dispersion Only
Explanation:
BF3 is non polar and nonpolar molecules only have london disperion forces
Answer:
375 g
Explanation:
Let the total mass of the solution = x g
Given that the mass of NaOH in the solution = 15.0 g
Thus, mass of the solvent = x - 15.0 g
Given that the mass % of the solution = 4 %
So,
So,
<u>Mass of the solution = 375 g</u>
A measure and or tendency, for the ability to attract electrons in a chemical bond is the atom's electronegativity.
Answer:
D. a relatively small fraction of the maximum number of possible hydronium ions.
Explanation:
A weak acid is an acid that is partially dissociated into its ions in an aqueous solution or water. A weak acid is one that does not dissociate completely in solution; this means that a weak acid does not donate all of its hydrogen ions (H+) in a solution
It is produced when an Arrhenius acid dissolves in water. So a weak acid would form a relatively small fraction of the maximum number of possible hydronium ions while in contrast a strong acid would form a relatively large fraction of the maximum number of possible hydronium ions.
