Choose ALL TRUE statements about calorimetry from the choices below:

Ostrovityanka [42]

Answer:

True statment

2) Styrofoam would make a good calorimeter

3) Insulating material would make a good calorimeter

Explanation:

The calorimeter is one which is insulated that is which will not absorb or let the heat to escape from it. the calorimeter is used to measure the heat change during a process so if it will allow to exchange heat with surrounding it will deviate the readings or observence.

Copper is a good conductor of heat so we cannot use it make a calorimeter.

Hence

1) Copper would make a good calorimeter : False

2) Styrofoam would make a good calorimeter: True

Styrofoam is a bad conductor or insulator so it can be and it is used for calorimeter.

3) Insulating material would make a good calorimeter : True

4) A good calorimeter should easily absorb heat : false

Choose the best answer below. Which of the following reactions will have the largest equilibrium constant at 298 K?

Maurinko [17]

Answer:

Explanation:

Relation between ΔG₀ and K ( equilibrium constant ) is as follows .

lnK = - ΔG₀ / RT

$K = e^{-\frac{\triangle G_0}{RT}$

The value of R and T are same for all reactions .

So higher the value of negative ΔG₀ , higher will be the value of K .

Mg(s) + N₂0(g) → MgO(s) + N₂(g)

has the ΔG₀ value of -673 kJ which is highest negative value . So this reaction will have highest value of equilibrium constant K .

Aneli [31]

Answer:

1. Phosphoric Acid : Catalyst

2. Methyl Anthranilate : Reactive

3. Sodium Nitrite : Reactive

4. Diethyl Ether : Solvent and reactant

5. Nitrogen : Sub-product

Explanation:

The phosphoric acid is used as a catalyst for the reaction, the methyl anthranilate will react with the sodium nitrite to produce methyl salicylate, along with the diethyl ether and the nitrogen is a sub-product of the reaction.
