Answer:
Atomic Mass
Explanation:
it is also sometimes below the symbol of the element :)
To determine the expected pH of the resulting solution of the following substances, create a balanced chemical equation of their ionization in water:
HI
HI + H2O ---> H+ + I-
It completely dissociates into H+ and I-. Due to the presence of the Hydronium Ion, the solution is acidic.
KBr
KBr + H2O ----> HBr + KOH
The salt KBr is formed by a strong base and a weak acid, therefore, the solution it forms with water is basic.
LiOH
LiOH + H2O ----> Li+ + OH-
It dissociates completely in water, turns into Li+ and OH-. Due to the presence of Hydroxide Ion, the solution becomes basic.
<span>Diffusion is a net movement of particles through a barrier driven by a concentration gradient. In diffusion, particles move from an area of higher concentration to the area of lower concentration in order to balance concentrations on the both sides of the barrier. For example, when you put a teabag into a hot water, concentration of tea particles in the hot water is much lower than in a teabag and the particles of tea will diffuse into water.</span>
