Answer:
Solubility indicates the maximum amount of a substance that can be dissolved in a solvent at a given temperature. Such a solution is called saturated. Divide the mass of the compound by the mass of the solvent and then multiply by 100 g to calculate the solubility in g/100g .
Answer: option D) energy was absorbed and entropy increased.
Explanation:
1) Given balanced equation:
2H₂O (l) + 571.6 kJ → 2 H₂ (g) + O₂(g).
2) Being the energy placed on the side of the reactants means that the energy is used (consumed or absorbed). This is an endothermic reaction.
So, the first part is that energy was absorbed.
3) As for the entropy, it is a measure of the disorder or radomness of the system.
Since, two molecules of liquid water were transformed into three molecules of gas, i.e. more molecules and more kinetic energy, therefore the new state has a greater degree of radomness, is more disordered, and you conclude that the entropy increased.
With that, you have shown that the right option is D) energy was absorbed and increased.

The substance will not sink in water, as it Dencity is (0.5)is less than the density of water (1gcm).
Answer:
Hi,
The assembling of proteins starts with the attachment of m RNA to the ribosomes in the cytoplasm. Each of the ribosome read the code in the m RNA from “start” to “ stop” choosing the specific amino acid building block and removing the unwanted growing protein. The ribosome performs this process in 0.02 seconds and with this rate it is possible for the cell to perform assembling of small protein such as insulin.
Best wishes!
