Answer:
Explanation:
oxygen is a 15 and nitrogen science chemistry i'm guessing
Moles of Hg
- Given mass/Molar mass
- 1.252/200.59
- 0.006mol
2 moles produce 1 mol O2
1 mol produces 1/2mol O_2
0.006 mol produces
Answer:
B. CCl₄
Explanation:
Solubility is determined by the principle , "like dissolves like" .
i.e. , if a compound is polar then it will dissolve in a polar compound only , and
if a compound is non - polar then it will dissolve in a non - polar compound only .
Hence , from the question ,
Benzene is a non - polar compound , i.e. does not separate out into poles , and hence , it will get dissolved into the CCl₄ , as it is too non - polar in nature , according to the above theory of solubility.
Hence, from the question,
Benzene will dissolve in CCl₄ .
Answer:
I believe it is a physical change
Explanation:
The telltale sign of a chemical change is the formation of a new substance. They also usually involve the production of energy (heat, light, sound etc.)
