In this reaction, reactant HgO decomposed into more than one products and reaction is called decomposition. Hg in HgO has oxidation number of +2 whereas oxidation number of Hg in product side is zero( zero because Hg is in its elemental form) so Hg is reduced. Hence option A is correct.
Decomposition can be defined as the “to break down” of complex substance or organic matter into a simpler inorganic matter.
It is one of the essential processes of the ecosystem, decomposition is a metabolic process which take up raw materials in the form of complex compounds, processing it and then converting it into simpler compounds.
some of the Bacteria, fungi and a few other microorganisms are involve in the process of decomposition as feed on dead organisms to survive.
in this process decaying and dead animals and plants serve as the raw materials undergo breakdown process and produces nutrients, carbon dioxide, and water; Microbes which involve in this process collectively known as saprophytes.

b. CCl2
c. CCl3
d. CCl4
A) 64.5%
B) 88.6%
C) 81.5%
D) 92.8%
Answer:
B) 88.6%
Explanation:
Percent yield equals actual yield divided by theoretical yield
actual yield is 31.0g
theoretical yield is 35g
percent yield was 88.57 which rounds up to 88.6%
The scientist that provided a foundation for John Dalton’s work on the atomic structure is Sir Joseph John Thompson or J.J. Thompson. It was theorized after the discovery that electrons are present in the atom. In this model, the atom is composed mainly of electrons. It was describe as plum pudding because the electrons are dispersed within the atom.
the most energy to remove an
electron?
Why do these elements have a higher ionization energy?
Answer:
Noble gases
Explanation:
The noble gases are non-metals that requires the highest amount of energy to remove an electron from their shells.
The reason for this difficult is that their electronic configuration confers a stable configuration them.
