The volume of water he dissolved the solute is 250 cubic centimeter.
<u>Explanation</u>:
Concentration = mass of solute in g / volume in dm^3
The concentration of a solution is defined as the ratio of mass of solute in grams to the volume of water in dm^3.
If concentration of a solution = 8 g/dm^3.
mass of solute =2 g.
Volume of a water = 2 / 8 = 0.25 dm^3. (or) 250 cubic centimeter.
Answer:
Diffusion and Dispersion.
Explanation:
The two processes that took place in the given experiment are Diffusion and Dispersion.
When a crystal of potassium magnet is added placed in the bottom of a beaker which contains cold water, after 5 minutes the particles of potassium magnet will diffuse with water through diffusion process and the colour of water turns purple.
After few hours, the colour of solution goes light purple because the tiny particles which were diffused earlier will dispersed in the water and the particles will spread and make the solution lighter in colour.
Hence, the two processes are Diffusion and Dispersion.
Answer:
El oxígeno, en concreto, tiene 2,6 electrones. Dichos electrones del oxígeno es la parte del número atómico que hace que la reacciones químicas del oxígeno sean de una manera determinada y, a su vez, distinta a la de otros elementos.
