Answer:

A) Concentration of A left at equilibrium of we started the reaction with [A] = 2.00 M and [B] = 2.00 M is 0.55 M.

B) Final concentration of D at equilibrium if the initial concentrations are [A] = 1.00 M and [B] = 2.00 M is 0.90 M.

[D] = 0.90 M

Explanation:

With the first assumption that the volume of reacting mixture doesn't change throughout the reaction.

This allows us to use concentration in mol/L interchangeably with number of moles in stoichiometric calculations.

- The first attached image contains the correct question.

- The solution to part A is presented in the second attached image.

- The solution to part B is presented in the third attached image.

A car has<br> weight of 10,ooow<br> What is the mass of the car<br> on earth (g=10N/KG)
Gre4nikov [31]

Answer:

1000 kg

Explanation:

We know the formula for finding out weight is W=mg

W= 10,000 N

M=?

g=10 N/KG

W=mg

10,000=10m

m=1000kg

Bingel [31]

Explanation:

A sound wave is often called a pressure wave because there are regions of high and low pressure established in them medium through which the sound wave travels. The regions of high pressure are known as <u>Compressions</u> and the regions of low pressure are known as <u>Rarefactions</u> . Sound waves are composed of compressions and rarefactions. Compressions are the parts where the molecules are congusted and pressed together. However in the rarefactions molecules are relax and have enough space for expansion. Sound waves are the logitudnal waves and always been defined as the motion of the medium particles parallel to the wave motion.

How are a symbol and a model both examples of a representation?
viva [34]

Answer:

A symbol and a model are both examples of a representation because they are presented in place of the real thing.

Explanation:

A symbol is a sign, a letter, mark, token, figure, or image used to stand in place of an object, function, or process.  For example, co2 is used in Chemistry to represent carbon dioxide.  There are many symbols representing other objects or meanings.  Mathematically, we can state that "a" equals 40.  "a" is a symbol representing the numerical value "40." Similarly, a model is a representation of a structure or a person on a smaller scale.  For example, Architects produce models of buildings and other projects that they design.
