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
C.a displacement reaction involving two metals
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.

A neutron star that spins and emits beams of energy is called a _____.protostar
red dwarf
white dwarf
pulsar
black hole

Answers

Answer:

The correct answer is pulsar.

Explanation:

Protostar : Its a young star with contracting mass which gains mass from its parent molecular cloud. At this stage fusion process does not start.

Red dwarf: A star having lower surface temperature , luminosity, mass and size than of the sun.

White dwarf : its an ultimate stage for an average mass star like sun . its a small dense star with size relatively equal to planet.

Pulsar : A rotating neutron star that emits beam of radio waves and other electromagnetic radiations.

Black hole: It is region of space time with very strong gravitational pull that even smallest particle or electromagnetic wave is incapable to escape it.

I believe its a pulsar

In the following reaction, how many liters of carbon dioxide will be produced if 250 liters of oxygen is used in the combustion of sucrose, given that both gases are at STP

Answers

The balanced reaction would be:

C12H22O11 + 12O2 = 12CO2 + 11H2O

We are given the amount of oxygen used in the combustion. This will be the starting point of our calculation. We use the ideal gas equation to find for the number of moles.

n = PV / RT = 1.00(250 L) / (0.08206 atm L/mol K ) 273 K
n= 11.16 mol O2

11.16 mol O2 (12 mol CO2 / 12 mol O2) = 11.16 mol CO2

V = nRT/P =11.16 mol CO2 x 273 K x 0.08206 atm L/mol K / 1 atm
V=250 L

Continued deforestation will most likely lead to _______.a.
a decrease in the number of endangered species
b.
an increase in the number of endangered species
c.
an increase in the number of oil and chemical spills
d.
a decrease in glacial melting

Answers

In the question "Continued deforestation will most likely lead to _______." the correct answer is "an increase in the number of endangered species" (option b).
Deforestation is the clearing of forest areas for use for non forest activities. Because there are a lot of animals that use forests as their home, clearing of the forest will make them homeless and will subject them to conditions that may lead to their death and possible extinction.

Answer:

Explanation:

Which event must always occur for a chemical reaction to take place?(1) formation of a precipitate(2) formation of a gas(3) effective collisions between reacting particles(4) addition of a catalyst to the reaction system

Answers

3 - Effective collisions between reacting particles

For a chemical reaction to occur, reacting particles must collide - however, not all collisions result in a reaction. They must have enough energy in the collision to react (that is, be above the activation energy). The rate of reaction is determined by the rate of successful collisions, that is to say, the more successful collisions there are in a unit time, the faster the reaction rate.

(3) effective collisions between reacting particles is your answer. Without these collisions, the reacting particles cannot trade particles or react with each other to create a chemical reaction.
