Answer: the strongest base will be A) HX(aq)
Explanation:
The cationic part of the base is formed from the cation in the weak acidic salt solution, (say Na2CO3= HY, and H= Na) i.e H+, whereas the anionic part of the base comes from the the weak base ( say NH4OH= HX, and X= OH-)
Then the strong base formed will be HX
Answer: Option (C) is the correct answer.
Explanation:
A physical substance that occupies space and has mass is called matter. Every matter possesses some chemical and physical properties.
Chemical property is the property which occurs when there is change in chemical composition of matter. Whereas physical property is the property which occurs when there is change in the appearance of matter.
The chemical properties of matter does not depend on temperature, therefore, option (a) is not correct.
Every matter posses some mass therefore, option (b) is also not correct.
It is possible for matter to have similar chemical properties and different physical properties. For example, a very small piece of sodium and a very large piece of sodium will react chemically in the same manner whereas their physical property, in this case is the size, is different. Therefore, option (c) is correct.
Every matter has some chemical and physical properties. Thus, it is not possible that matter can have only physical property and no chemical property. Hence, option (d) is also not correct.
Thus, we can conclude that the statement it is possible for matter to have similar chemical properties and different physical properties is true about matter.
The atomic number is the total number of protons in an atom.
