The answer would be soluble. Think of it like salt. On it's own it is the white substance that you can see, but when you put it in water and stir it disappears. It is still there, but the physical appearance has changed. Also being explosive, flammable, and reactive are all chemical properties. Hope this helped!
Answer:
Force arrows are used to represent both the magnitude and direction of forces. The length of the arrow corresponds to the magnitude of the force, with longer arrows indicating forces with larger magnitudes. :) hope this helps

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.
For 5.43 g/mL and 5.44 g/mL = 0.01 the least diff and most precise.
First of all, precision is determined by the difference in the two obtained values. If the difference between the two values obtained is less, then precision is more. If the difference between the two values obtained is more, then precision is less.
For 5.43 g/mL and 5.44 g/mL , we can see that the difference between these two data is 0.01
For 7.98 g/mL and 7.91 g/mL , we can see that the difference between these two data is 0.07
For 7.65 g/mL and 7.64 g/mL , we can see that the difference between these two data is 0.01
For 7.06 g/mL and 7.03 g/mL , we can see that the difference between these two data is 0.03
As we can see that, the most difference between the data is 0.07 between 7.65 g/mL and 7.64 g/mL and thus, they are least precise.

Answer:
True.
Explanation:
Iodine is an essential element required for the synthesis of Thyroxine is a correct statement.
Iodine is an essential and controlling medium for thyroid hormone production, as a minor ingredient. It is an important element in the development of thyroid hormones thyroxine (T4) and triiodothyronine (T3) by the thyroid gland.
