149g/mol is the gram-formula mass of (NH)PO. Therefore, the correct option is option C.
The quantity of a compound which has the exact same mass in grammes that its formula mass in an atomic mass unit is said to have the compound's gramme formula mass. Each atom of every component has a distinctive mass, and every molecular unit of a compound possesses a distinctive mass determined by the complex's formula. It is referred to as the Gramme Formula Mass because the formula-determined mass of a substance that is ionic is calculated by adding the atomic masses of each of its constituents. Gram-formula mass of (NH)PO = (14+4)×3+31+16×4= 149g/mol
Therefore, the correct option is option C.

Answer:
Need a control group.
Explanation: Without a control group you would not be able to interpret the results correctly.
Answer: The correct answer is Option a.
Explanation:
Entropy is defined as the measurement of randomness in a system.
Entropy increases as we move from solid state to liquid state to gaseous state and it decreases as we move from gaseous state to liquid state to solid state.
From the options above:
Option a:
Entropy is getting decreased because liquid reactants are changing its state to solid state.
Option b:
In this reaction, entropy is increasing because the state is changing from liquid to gaseous state.
Option c:
In this reaction, entropy is increasing because the state is changing from liquid to gaseous state.
Option d:
In this reaction, entropy is increasing because the state is changing from solid to gaseous state.
Hence, the correct answer is Option a.
Answer: Option (3) is the correct answer.
Explanation:
When a compound dissolved in solution dissociates into ions then the solution is able to conduct electricity is known as an electrolyte.
This means that ionic molecules are able to conduct electricity because they are able to dissociate into ions.
Thus, we can see that out of the given options NaOH is ionic in nature hence, it is an electrolyte.
Whereas , , and are not ionic in nature therefore, they are not electrolyte.
An electrolyte is a substance that produces an electrically conducting solution when dissolved in water. Electrolytes are typically salts that dissociate into ions. Out of the given options, NaOH is an electrolyte as it can dissociate into Na+ and OH- ions. The correct option is 3.
An electrolyte is a substance that produces an electrically conducting solution when dissolved in a polar solvent, such as water. It is typically formed when a salt dissociates into its component ions.
The free ions in the solution interact with the polar solvent (water), allowing the solution to conduct an electric current. In the options given, NaOH(option 3) is considered an electrolyte as it can dissociate into Na+ and OH- ions, thereby allowing the solution to conduct electricity.The correct option is 3.
