In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture.
Explanation:
if non science related concentration is also about focusing(non-science related definition) : )
Answer:
1. because what if you do a incorrect ion? it would be all wrong! 2. you dont get it quickly because! you might get the wrong equipment. 4. yep! no food or drinks!
Explanation:
hope this helps ☻︎
Answer:
C. it would form a anion with a -1 charge.
Explanation:
The elements of group 17 are called halogens.
These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their boiling points also increases down the group which changes their physical states. i.e fluorine is gas while iodine is solid.
They require only one electron to complete the octet and get stable. Thus they form anion with charge -1 when they gain electron.
l + e⁻ → I⁻
They form ionic compound with alkali and alkaline earth metal such as sodium chloride (NaCl), Barium iodide (BaI₂) etc.
Properties of Iodine:
1. it is present in solid form.
2. it is crystalline in nature.
3. it is very corrosive and has pungent odor.
4. it can not react with oxygen and nitrogen.
<span>C)Solid particles become evenly dispersed among liquid particles.
When you dissolve a solid in water, it breaks into its constitutive particles/ions, which becomes solvated by the water molcules, thus enabling a quasi-uniform distribution of the solid particles.</span>
