Answer:
C
Explanation:
okay, you need to look at the structures of the particles of matter in the solid, liquid and gas.
- particles in a solid are in fixed positions, where they can only vibrate in those positions ( take a look at ice, or rather, a brick)
- liquids have very small or rather, no spaces between them, but they can slide or rub against each other, like people in a <em>really tight</em> crowd I guess
- gas particles have very large spaces between them and they move randomly. these exibit what's called brownian motion.
- since water particles (and all other liquid particles) have negligible spacings and limited movement, that allows the dye particles to move from a region of high concentration to that of a low concentration. the aim for this is for the mixture/solution to reach an equilibrium, that is the mixture must get to a point where all regions have the same concentration of the dye.
you can refer to your coursebooks :)
correct where wrong please:)
Answer:
Radicals
Explanation:
A radical refers to a chemical specie that contains unpaired electrons in their dot electron diagrams.
Radicals contain an odd number of electrons. They are commonly called odd electron species.
Radicals participate in a number of important reactions. A typical example is the halogenation of alkanes in the presence of light.
Examples of radicals include; Br. , Cl. , F. etc
<h2>~<u>Solution</u> :-</h2>
- Here, to find the atomic mass of element, we must;
We know that,
- 4.6 x $ \sf{10^{22}}$ atoms of an element weigh 13.8g.
Thus,
The atoms of $ \sf{ 6.02 \times 10^{13}}$ will weigh;
![= \sf{\frac{13.8 \times 6.02 \times {10}^{23} }{4.6 \times {10}^{22} } } \\](https://tex.z-dn.net/?f=%20%3D%20%20%20%5Csf%7B%5Cfrac%7B13.8%20%20%5Ctimes%206.02%20%5Ctimes%20%20%7B10%7D%5E%7B23%7D%20%7D%7B4.6%20%5Ctimes%20%7B10%7D%5E%7B22%7D%20%7D%20%7D%20%5C%5C%20)
![= \sf{180.6 \: g \: \: (molar \: mass)}](https://tex.z-dn.net/?f=%20%3D%20%20%5Csf%7B180.6%20%5C%3A%20g%20%5C%3A%20%20%5C%3A%20%28molar%20%5C%3A%20mass%29%7D)
- Hence, the molar mass (atomic mass) will be <u>180.6 g.</u>
