Answer:
B
Explanation:
Because it is viewed in a different place
Answer:
The polar nature of water splits the acid molecules into its cations and anions. Cations and anions are charged particles and are free to move inside the aqueous medium. As a result when a potential difference has applied the solution to conduct electricity.

An ideal gas is cooled at constant pressure, option A. A. ΔH is less than (more negative) Δ E of the system.
∆H is the exchange in enthalpy from reactants to products A ΔHº charge represents an addition of electricity from the reaction and from the surroundings, resulting in an endothermic response. A horrible cost for ΔHº represents the removal of power from the reaction and into the surroundings and so the reaction is exothermic.
The enthalpy of a system can not be measured right away because of the fact the inner energy consists of additives that are unknown, now not effects available, or aren't of interest in thermodynamics.
Hence, the answer is option A.

Chloromethane has a boiling point of -11.56°F
Oxygen has a boiling point of -297.3°F
<u>Sodium chloride has a boiling point of 2,669°F</u>
Isopropyl alcohol has a boiling point of 180.5°F
<u><em>So sodium chloride has the highest boiling point.</em></u>
Answer:
Options (A), (B) and (C)
Explanation:
In an ecosystem, the transfer of nutrients takes place from one place o another. This input and output of nutrients continuously takes place in the ecosystem.
- The rainwater is also essential as it carries a certain amount of valuable nutrients such as calcium, fluoride, magnesium, and iron that are mixed with water, and this enriches the fertility of the soil and the water is taken up by the roots of the plants for the growth and expansion of plants.
- The nitrogen-fixing bacteria refers to those micro-organisms that are present in the soil and helps in the conversion of the atmospheric nitrogen into nitrogen compounds, which are helpful for the enhancement of the soil fertility.
- Chemical weathering usually refers to the process by which the rocks disintegrates due to the effect of chemical reactions. The micro-organisms and the plant roots release some acids sometimes that react with the rocks and help in breakdown releasing the nutrients that are stored in the rocks. This eventually mixes up with the soil and increases the quality of the soil.
Thus, the correct answers are options (A), (B) and (C).
