Answer:
4.62
so 5
the ratio is 2 na chlorates for 3 O2 so multiply 7 by 2/3
Explanation:
The rule of solubility states that, like dissolves like. Water is a polar compound. Hence compound that is most polar, will dissolve maximum in water.
Among to available options, ethanol has maximum polarity. Hence, its solubility will be maximum in water.
Other solvents like benzene, toluene and carbon tetrachloride are non-polar in nature. Hence, they show poor solubility in water.
Answer :
(1) is act as a base and act as an acid.
(2) We can not classified as a base or an acid.
Explanation :
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydronium ions in water.
(1) The given chemical reaction is:
In this reaction, produces ions and produces ions.
Thus, is act as a base and act as an acid.
(2) The given chemical reaction is:
Arrhenius concept is only applicable on aqueous solution. Thus, we can not classified as a base or an acid.
Answer:
umm well when a reaction happens it's chemical and when you put like salt and pepper or cookies and crackers its physical
