Answer:
cohesion
Explanation:
just got it right
Cohesion
"cohesion: the attraction between molecules within a substance; the tendency of the molecules of a substance to "stick together" or group together" (edge)
It is based on testable and replicable evidence.
Answer: 1.8 moles Fe and 2.7 moles are produced.
The balanced chemical reaction is:
According to stoichiometry :
3 moles of require 1 mole of
Thus 2.7 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 3 moles of give = 2 moles of and 3 moles of
Thus 2.7 moles of will give = of and of
Thus 1.8 moles Fe and 2.7 moles are produced.
Al(OH)4-(aq) plus 4H plus (aq) and Al3 plus (aq) plus 4H20(I)

pH=-log(x)
x=0.001M,pH=3
x=0.01M,pH=2
x=0.1M,pH=1
x=1M,pH=0
Highest pH is for option D
