One cubic meter of an ideal gas at 600 K and 1000 KPa expand to five times its initial volume as follows:(a) By a mechanically reversible, isothermal process [T 2 = 600K; P 2 = 200kPa; W= -1609 kJ]


(b) By a mechanically reversible, adiabatic process [T 2 =208.96K; P 2 = 67.65 kPa; W= -994.4 kJ] For each case calculate the final temperature, pressure and the work done by the gas. C p =21 Jmol- 1K-1.

The diameter of an atom is approximately 1 * 10 ^ - 10 * m . What is the diameter in decimeters?

Answers

Answer:

d=1x10^(-9)dm

Explanation:

Hello,

In this case, considering that 1 m equals 10 dm, the required diameter of the atom in decimetres is:

d=1x10^(-10)m*(10dm)/(1m) \n\nd=1x10^(-9)dm

Best regards.

Final answer:

The diameter of an atom is approximately 1 * 10^-10 * m, which translates to 1 * 10^-11 decimeters by multiplying the meter measurement by 10.

Explanation:

The subject of this question is a unit conversion. We are trying to convert the diameter of an atom from meters to decimeters.

The process is as follows:

  • First, we need to understand that 1 meter equals 10 decimeters because the prefix 'deci-' means one-tenth.
  • So, if the diameter of an atom is approximately 1 * 10^-10 * m, then in decimeters the diameter would be 1 * 10^-11 * dm

In essence, to convert meters to decimeters, we need to multiply the meter measurement by 10. But because the meter measurement of the atom is in the power of -10, the decimeter equivalent would be in the power of -11.

Consider the following mechanism: O3 => O2 + O NO + O => NO2 What is the role of O2? A. intermediate B. catalyst C. reactant D. product

Answers

The role of O_2 should be option D. product

Role of oxygen:

Since

O_3 \rightarrow O_2 + O

And,

NO + O \rightarrow NO_2

Now

Here we have to add all these

So, it should be O_3 + NO\rightarrow O_2 + NO_2

Therefore, The role of O_2 should be option D. product

learn more about oxygen here: brainly.com/question/16717574

Answer:

The correct answer is option D.

Explanation:

Step 1: O_3\rightarrow O_2+O

Step 2: NO+O\rightarrow NO_2

Overall reaction can be determined  by adding all the reactions of mechanism:

O_3+NO\rightarrow O_2+NO_2

Reactants in an overall reaction = O_3\& NO

Products in an overall reaction = O_2\& NO_2

According to question , the role of oxygen gas is product.
