The equilibrium reaction, causes the water dissociation constant, Kw, is 1.01 × 10-14<span> at 25 °C. That is because every H</span>+<span> (H</span>3O+) ion these forms accompanied by the formation of an OH-<span> ion, are the concentrations of these ions and in pure water the same thing can be calculated from </span>Kw<span>.

Answer:
Los huesos se mantienen unidos a otros huesos a través de unas largas tiras fibrosas llamadas ligamentos. El cartílago, una sustancia flexible y elástica que contienen las articulaciones, sujeta los huesos y los protege en los puntos donde varios huesos friccionan entre sí.
Answer:
See Explanation
Explanation:
Let us find the number of moles of each element
For iron = 2.24g/56 = 0.04 moles
For oxygen = 0.96 g/16 = 0.06 moles
Then we divide by the lowest ratio;
0.04/0.04 and 0.06/0.04
1 and 2
We Thus obtain 1 : 1.5
Multiplying through by 2 we have; 2 : 3
The formula of the oxide formed is Fe2O3
The balanced equation is;
4Fe + 3O2 ------> 2Fe2O3
Diffusion is the physical process whereby atoms or molecules tend to move from an area of higher concentration or pressure to an area of lower concentration or pressure.
In the field of science, diffusion can be described as a process in which molecules move along the concentration gradient i,e from a region of higher concentration to a region of lower concentration.
The process of diffusion is extremely useful in many everyday living conditions. For example, it is due to diffusion that carbon dioxide and oxygen are exchanged between the lungs and the blood. Diffusion of water, salts, and water is an important process that occurs in the kidneys.
We can divide diffusion into two main types which are simple diffusion and facilitated diffusion. Simple diffusion occurs without any carrier molecule. On the other hand, facilitated diffusion occurs with aid of a carrier molecule.

D because evaporation travels the water through the air and condensation turns it into clouds
