Consider the reversible reaction.

Chemistry
1 answer:
Dmitry [639]2 years ago
3 0

Answer:

Option D is correct.

The concentrations of both PCl₅ and PCl₃ are changing at equilibrium

Explanation:

Chemical equilibrium during a reversible chemical reaction, is characterised by an equal rate of forward reaction and backward reaction. It is better described as dynamic equilibrium.

This is because, the concentration of the elements and compounds involved in the reversible chemical reaction at equilibrium changes, but the rate of change of the reactants is always equal to the rate of change of products.

Hence, the concentration of reactants and products, such as PCl₅ and PCl₃ are allowed to change at equilibrium, but alas, the rate of forward reaction must always match the rate of backward reaction for the process to remain in a state of Chemical equilibrium.

Hope this Helps!!!

S_A_V [24]

Answer:

Rainfall - precipitation

disappeared puddles - evaporation

cloud formation - condensation

Explanation:

Rainfall that is observed by the Susan is the precipitation of the water cycle in which the water vapor that was condensed become heavy and form droplets of water and fall from sky to the earth surface.

Puddles that formed due to rainfall are the collection of water in the water cycle which is evaporated (process: evaporation) into the atmosphere n the form of water vapor which condensed to form clouds.

How did humans and animals adapt/survive to hurricane Katrina? AND Give examples of organisms that could not adapt/survive? PLS
guajiro [1.7K]
Some organisms that could not survive where cats, dogs, birds, horses, fish, cows, every animal that was in hurricane Katrina was affected by it. Some of these animals were able to survive and others were rescued from near death.
Most of the animals could not adapt to this change because they are not used to this type of change. The water was too strong for the fish and when the water brought the fish into any water/sea animal there was also medal because the water in through peoples houses (pretty much the man-made stuff that's not meant for sea is killing the animals in the water). 
Any animal that was left behind was affected. The animals could not adapt to this change they have never experienced something that tragic before, how they survived? Well, the animals that survived was mainly because of there natural instinct, before an earthquake or anything hits there are many animals that can sense the storm coming before it even hits and in this situation, the animal could, wake up, run to owner, flee, run to higher ground, and if they cant sense it. They see whats going on around them and then they know something is wrong.

When 9.36 g sodium hydroxide is dissolved in enough water to make a total volume of 965 mL, what is the concentration of the res
SSSSS [86.1K]

Answer:

0.2425 M

Explanation:

Given mass = 9.36 g

Molar mass of NaOH = 39.997 g/mol

The formula for the calculation of moles is shown below:

moles = \frac{Mass\ taken}{Molar\ mass}

Thus,

Moles= \frac{9.36\ g}{39.997\ g/mol}

Moles\ of\ NaOH= 0.234\ mol

Given that:- Volume = 965 mL = 0.965 L ( 1 mL = 0.001 L )

So,

Considering:

Molarity=\frac{Moles\ of\ solute}{Volume\ of\ the\ solution}

Molarity=\frac{0.234\ mol}{0.965\ L}=0.2425\ M

Write the balanced chemical equation for the following: The destruction of a marble statuary by acid rain: aqueous nitric acid r
Mashcka [7]

Answer: The coefficient in front of nitric acid is 2

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas. Liquids are represented by (l) and gases are represented by (g).

The balanced chemical reaction is :

CaCO_3(s)+2HNO_3(aq)\rightarrow Ca(NO_3)_2(aq)+CO_2(g)+H_2O(l)
