The correct answer for the question that is being presented above is this one: "They are both balanced chemical equations." The statement that is correct about the chemical reaction is that both chemical reaction are balanced chemical equations.

Elements in a given period of the periodic table contain the same number of

Answers

A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells.

What are electron shells?

An electron shell is the outside part of an atom around the atomic nucleus.

Elements present in horizontal rows are called periods.

Elements belonging to the same period have same no. of the shell as the electrons are added in the same shell of the element.

Electron shells. As the atomic number grows inside a period the electrons are added to a same shell.

Air bags, which act as safety devices in cars, contain solid sodium azide. On impact, the sodium azide releasesnitrogen gas, which expands the air bag. The main benefit of using a gas instead of another type is that —
A. gas molecules are subject to ionic bonding
B. the separation of gas molecules is much greater than the volume they occupy
C. gases won’t explode the bag on very hot days
D. gas molecules don’t transfer excess Kinetic Energy

Answers

The answer is; D

The reason for this is because gases are compressible . Much of the energy of the impact created when your head hits the air bad is absorbed by the gas (through compression and rarefaction) hence reducing the damage to the head in case of an accident.

Which type of reaction occurs in the following? 2HgO(s) 2Hg(l) + O2(g)A.a decomposition reaction in which a metal is reduced
B.an acid-base neutralization reaction to produce oxygen gas

D.a combustion reaction involving burning a metal in oxygen

Answers

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.

what is decomposition ?

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.
