Answer: It decreases.
Explanation: Solubility of gas in a particular liquid is the volume of gas in ml that can dissolve in unit volume of the liquid to form the saturated solution at the given temperature and under a pressure of 1 atmosphere.
Effect of temperature on solubility of gas:
Solubility of gas decreases with increase in temperature as on heating some gas is expelled out of the solution.
According to Le Chateliers principle , on increasing the temperature, the reaction will shift in a direction where temperature is decreasing i.e. backward direction and thus the solubility would decrease.
It dissolves.
It increases the pH of the solution.
It releases hydroxide ions.
Answer: Option (a) is the correct answer.
Explanation:
An acid-base indicator is an indicator which changes color according to the pH of solution in which it is placed.
For example, phenolphthalein is an acid-base indicator.
Thus, we can conclude that out of the given options, an acid–base indicator react by changing color when placed in an acidic solution, is the correct option.
B. nitrogen (N), bismuth (Bi), antimony (Sb)
C. antimony (Sb), nitrogen (N), bismuth (Bi)
D. bismuth (Bi), antimony (Sb), nitrogen (N)
Answer: Option (A) is the correct answer.
Explanation:
Nitrogen is a non-metal and it is known that non-metals do not conduct electricity. Thus, it will be least conductive out of the given options.
Whereas antimony (Sb) is a metalloid. Metalloid are the substance that show properties of both metals and non-metals. Thus, antimony will conduct electricity.
On the other hand, bismuth (Bi) is a metal hence, it will conduct electricity.
Thus, we can conclude that the order from least conductive to most conductive will be nitrogen (N), antimony (Sb), bismuth (Bi).
Answer: The correct answer is Option A.
Explanation:
Conductivity of an element is defined as the tendency to conduct electricity. This property is shown mostly by metals and then by some metalloids and least by non-metals.
Metals are defined as the elements which loose electrons easily and thus can easily conduct electricity due to the presence of free electrons.
Metalloids are defined as the elements which show the properties of both metals and non-metals. Some metalloids are conductive, some are not.
Non-metals are defined as the elements which gain electrons easily and thus cannot conduct electricity easily and are considered as non-conductive.
From the given options:
All the three elements belong to same group but nitrogen is a non-metal, antimony is a metalloid and Bismuth is a metal.
Thus, the order of conductivity follows:
Hence, the correct answer is Option A.
