Answer:
259 mg is the mass of silver chloride required to plate 195 mg of pure silver.
Explanation:
Silver chloride contains 75.27 percent silver. It can be concluded that:-
For every 100 mg of silver chloride, 75.27 mg of silver we can get.
So, to produce 195 mg of silver, the amount of silver chloride required can be calculated as:-
<u>259 mg is the mass of silver chloride required to plate 195 mg of pure silver.</u>
Answer:
A. Vegetable oil
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 ,
A. Vegetable oil is a non polar compound ,
B. Polar compound
C. ionic compound , is a polar compound .
Since , wate is polar in nature , hence it will get dissolved in a only polar compound ,
Therefore ,
Water will not get dissolved in vegetable oil , being it a non - polar compound .
Looks to me like C and O are virtually equal and H is double those, so:
CH_20, which is the empirical formula for carbohydrates.
Some examples:
- the sun
- a flashlight turned on
- a light bulb
- stars
- fireflies
...hope i helped :)
In order to find out the ranking of ions basicity, check the
pKa values of each ions. The principle that you need to remember is that the
stronger the acid the weaker the corresponding conjugate base. The pKa dictates
acid value of the compound. The answer would be CH3NH, CH3O-, and CH3CH2-.
