What’s the difference between heterogeneous and homogeneous mixtures?

Chemistry
1 answer:
Ronch [10]3 years ago
5 0

Answer:

Mixtures can be either homogeneous or heterogeneous. A mixture in which its constituents are distributed uniformly is called homogeneous mixture, such as salt in water. A mixture in which its constituents are not distributed uniformly is called heterogeneous mixture, such as sand in water.

Which of the following is consistent with a reaction that proceeds spontaneously in the reverse direction (assume all variables
elena-s [515]

Answer:

B. ΔG > 0, Q > K

Explanation:

For reverse reaction to take place Q should be greater than K

Since reverse reaction should be spontaneous, forward reaction should be non spontaneous.

So, for forward reaction, ΔG > 0

Hence, the correct answer is B

Predict the sign for AS for each of the following systems: Water freezing Water evaporating Crystalline urea dissolving Assembly
djyliett [7]

Answer:  1.  Water freezing : \Delta S is -ve.

2. Water evaporating : \Delta S is +ve.

3. Crystalline urea dissolving : \Delta S is +ve.

4. Assembly of the plasma membrane from individual lipids: \Delta S is -ve.

5.  Assembly of a protein from individual amino acids: \Delta S is -ve.

Explanation:

Entropy is defined as the measurement of degree of randomness in a system.

It is represented by symbol S and we can only measure a change in entropy which is given by \Delta S.

If there is decrease in randomness , the sign for \Delta S is -ve and If there is increase in randomness , the sign for \Delta S is +ve.

1.  Water freezing: Entropy decreases as we move from liquid state to  to solid state and thus \Delta S is -ve.

2. Water evaporating : Entropy increases as we move from liquid state to  gaseous state and thus \Delta S is +ve.

3. Crystalline urea dissolving : The molecules convert from solid and ordered state to aqueous phase and random state. Thus the entropy increases and thus \Delta S is +ve.

4. Assembly of the plasma membrane from individual lipids:  random lipids are associating to form a single large polymer and thus entropy decreases and thus \Delta S is -ve.

5. Assembly of a protein from individual amino acids: random amino acids are associating to form a single large polymer and thus entropy decreases and thus \Delta S is -ve.

What is the purpose of the periodic table?
Charra [1.4K]

Answer:

the periodic table is important because it is organized to provide a alot of information about elements and how they relate to one another in one easy-to-use reference. The table can be used to predict the properties of elements, even those that have not yet been discovered.
