The answer is: D.oxymoron.
The oxymoron is a combination of contradictory or incongruous words.
In this example, deafening silence.
Deafening is a noise so loud as to make it impossible to hear anything else.
Silence is oposite of deafening, complete absence of sound.
Other examples are: big baby, original copy, living dead, sweet sorrow, soft rock, pretty ugly.
A. AgCrO4(s) + Na2NO3(aq)
B. Ag2CrO4(s) + NaNO3(aq)
C. Ag(CrO4)2(s) + Na2NO3(aq)
D. Ag(CrO4)3(s) + Na(NO3)2(aq)
The products obtained when 2 AgNO₃ + Na₂CrO₄ reacts is Ag₂CrO₄ + 2 NaNO₃.
The reaction in which reduction and oxidation takes place simultaneously
by obtaining or losing an electron, the oxidation number of a molecule, atom, or ion varies.
In the question it is given that
AgNO₃(aq) + Na₂CrO₄(aq) → and we have to predict the products
So Silver Nitrate when reacts with Chromic Acid to from silver Chromate and sodium nitrate.
2 AgNO₃ + Na₂CrO₄ → Ag₂CrO₄ + 2 NaNO₃
Therefore Product B is the correct answer.

B.an acid-base neutralization reaction to produce oxygen gas
C.a displacement reaction involving two metals
D.a combustion reaction involving burning a metal in oxygen
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.

The rates of the forward and reverse reactions are unequal.
The concentrations of the products and reactants do not change.
The forward reaction stops at 500 K.
The correct option is this: THE CONCENTRATION OF THE PRODUCTS AND THE REACTANTS DO NOT CHANGE.
A reversible chemical reaction is said to be in equilibrium if the rate of forward reaction is equal to the rate of backward reaction. At this stage, the concentrations of the products and the reactants remain constant, that is, there is no net change in the concentration even though the reacting species are moving between the forward and the backward reaction.
