Convert 121 points for K PA into TORR

1 answer:

5 0

121 kPa to Torr?

we need a couple of conversions

1 atm = 760 torr
1 atm= 101 kPa

now we use them

121 kPa $\frac{1 atm}{101 kPa}$ x $\frac{760 torr}{1 atm}$ = 910 torr

Answer:

1. Elements

2. one

3. properties

4. Chemical

5. metal

6. non-metal

7. metalloids

8. Compounds

9. one

10. more

11. components

12. chemical process

Explanation:

In the given paragraph a brief about the difference between element and compound is given.

Elements are made up of the same type of atoms and each element is made up of one atom, that is they cannot be broken down into any other substance. Each element is different from each other due to its properties, though some have the same physical properties but are different in chemical properties. Elements can be classified as metals such as iron and silver, non-metals such as oxygen and hydrogen, and metalloids such as boron and silicon.

Compounds are a combination of one or more elements such as water and salt. Compounds can be easily broken down into components through a chemical process.

Hence, the correct answer is:

1. Elements

2. one

3. properties

4. Chemical

5. metal

6. non-metal

7. metalloids

8. Compounds

9. one

10. more

11. components

12. chemical process

Two perfumes are released at the same time. If one is standing 7.5 m from the point of release. Perfume A (molar mass 275 g/mol)

natta225 [31]

According to Graham's Law of Diffusion," Diffusion of Gas is inversely proportional to square root of its Molecular Mass or Density".

rᵇ/rᵃ =   $\sqrt{da/db}$
Or,
  rᵇ/rᵃ =   $\sqrt{Ma/Mb}$ ----- (1)
As,
Ma = 275 g/mol

Mb = 205 g/mol

Putting Values in eq.1,

rᵇ/rᵃ =   $\sqrt{275/205}$

rᵇ/rᵃ = 1.15

Result:
Perfume B will diffuse 1.15 times faster than Perfume A. Hence, Perfume B will be first smelled by the person.
