Combustion means the burning of something. So in the given question, you could say, “In this question, combustion means the burning of methane”.
Answer:
(D) Neither I nor II
Explanation:
The reagent potassium hydrogen phthalate is found in pure form and it is not partially hydrated .
The pallet form of NaOH ( solid form ) absorbs carbon dioxide gas from the atmosphere but NaOH in solution form does not absorb carbon dioxide .
Hence option D ) is right choice .
<span>An ecosystem is a complete community of living organisms and the nonliving materials of their surroundings. Thus, its components include plants, animals, and microorganisms; soil, rocks, and minerals; as well as surrounding water sources and the local atmosphere. The size of ecosystems varies tremendously. An ecosystem could be an entire rain forest, covering a geographical area larger than many nations, or it could be a puddle or a backyard garden. Even the body of an animal could be considered an ecosystem, since it is home to numerous microorganisms. On a much larger scale, the history of various human societies provides an instructive illustration as to the ways that ecosystems have influenced civilizations.

The final temperature of the mass of gold is 737 °C.
<h3>What is the specific heat capacity of gold?</h3>
The specific heat capacity of gold is 0.126 J/g/K
The final temperature, T2 of the gold is calculated as follows:
T2 = T + Q/mc
where;
T is initial temperature, m is mass, and c is specific heat capacity of gold.
T2 = 27 + 2.3 x 1000/(25 x 0.126)
T2 = 737 °C
Therefore, the mass and heat capacity of gold determines its final temperature.
