Colligative properties depend on the quantity of solute and solvent and the identity of the solvent.
Explanation:
Colligative properties are defined as a set of intensive physical properties that result from the interactions between solute and solvent that form a solution. In this group of properties, we can find the freezing point depression, boiling point elevation, osmotic pressure, and vapor pressure lowering.
The mentioned properties dependon the amount of solute and solvent (concentration) and the nature of the solvent. this fact can be pictured by the freezing point depression formula:
where is the freezing point of the pure solvent,
is the freezing point of the solution,
is the freezing point depression constant and m is the molality
In the equation, it can be seen that the change of temperature of the solution with respect to the pure solvent depends on the molality, which is the ratio of moles of solute and mass of solvent. Moreover, the change also depends on the freezing point depression constant that is a characteristic of the solvent.
If not, was energy released (exothermic) or absorbed (endothermic) by the molecules during this physical change?
Answers
Answer:
Answer is C because in exothermic reactions, energy releases.
in Cellular respiration,
ATP+H20 (water) = ADP+ Pi + Energy
So celullar respiration is exothermic and releases energy
Answer:
yes it is

(K) potassium is the metal that will react most readily with 1.0 M HCl to produce H2(g).
What is potassium?
Potassium is a silvery-white metal with the symbol K and atomic number 19.
The reaction will be
The potassium will react with HCl to produce potassium chloride and hydrogen gas.
It is a single displacement reaction.
In this type of reaction, more reactive metal is displaced with less reactive metal.
Thus, the correct option is 2) K.

Answer: The correct answer is Option 2.
Explanation:
The reaction between a metal and HCl is a type of single displacement reaction.
Single replacement reactions are defined as the reactions in which more reactive metal replaces less reactive metal from its chemical equation. The reactivity is determined from the series called reactivity series. The metal lying above in the series is more reactive than the metal lying below in the series.
General equation for these types of reactions is:
From the series attached below, the most reactive metal is Potassium (K).
Increasing order of the reactivity of metals are:
Hence, the correct answer is Option 2.
