<em>Answer:</em>
- PbS are not soluble in water.
<em>Solubility rule:</em> "<em>Like dissolve like</em>"
<em>Reason of insolubility of PbS.</em>
- When sulphides are attached with group one and group two elements of periodic table, they are soluble but when they are attached with transition metals like Pb, there is highly covalent bond which makes difficult dissociation of bonds in water.
- KClO2 and NH4Br are inoic substances , so they are easily soluble. HNO2 is weak acid which can ionize in water.
Answer:
The mass of solution will be "395.78 g".
Explanation:
Given:
Mass of acetic acid,
= 30 g
Percentage,
= 7.58% w/w
Now,
⇒ % ![=\frac{Mass \ of \ acetic \ acid}{Mass \ of \ solution}\times 100](https://tex.z-dn.net/?f=%3D%5Cfrac%7BMass%20%5C%20of%20%5C%20acetic%20%5C%20acid%7D%7BMass%20%5C%20of%20%5C%20solution%7D%5Ctimes%20100)
By putting the values, we get
⇒ ![7.58=\frac{30}{Mass \ of \ solution}\times 100](https://tex.z-dn.net/?f=7.58%3D%5Cfrac%7B30%7D%7BMass%20%5C%20of%20%5C%20solution%7D%5Ctimes%20100)
⇒ ![Mass \ of \ solution=\frac{30\times 100}{7.58}](https://tex.z-dn.net/?f=Mass%20%5C%20of%20%5C%20solution%3D%5Cfrac%7B30%5Ctimes%20100%7D%7B7.58%7D)
⇒ ![=\frac{3000}{7.58}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B3000%7D%7B7.58%7D)

Answer:
i was thinking it would be best to use dish cloth
Explanation:
if u just use a plastic scrubber to wash dishes than it would be most likely to make it more duty than using a cloth however it is clean only problem for dish cloth is after using it for 2 or 3 months most likely two you would have to wash i know this because I've done it before and i found out that dish cloth is much better and safer to use. i pray i got the right answer if not hey i was just trying to help y'all its alright with me
Answer:
Carbon and phosphorus
Explanation:
The atoms of carbon and phosphorus are most likely to gain electrons from the given choices .
The reason for this is because, both carbon and phosphorus are non-metals. Most non-metals usually accept electrons.
Metals are usually electron donors .
- Metals are known for their electropositivity which is their ability to lose electrons.
- Non-metals are electronegative and will tend to have a strong affinity for electrons.
