Answer:

P2 = 1250mmHg

Explanation:

V1 = 5.0L

P1 = 750mmHg

V2 = 3.0L

P2 = ?

According to Boyle's law, the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant.

P = k/V k = P*V

P1*V1 = P2*V2 = P3*V3 =........=Pn*Vn

P1 *V1 = P2 * V2

Solve for P2

P2 = (P1 * V1) / V2

P2 = (750 * 5.0) / 3.0

P2 = 3750 / 3

P2 = 1250mmHg

The final pressure of the gas is 1250mmHg

What is the solution to the problem expressed to the correct number of significant figures? 12.0/7.11=?
xxMikexx [17]

Answer:

1.69.

Explanation:

  • The solution = 12.0 / 7.11 = 1.687 = 1.69.
  • The rule of significant figures for division states that: the results are reported to the fewest significant  figures.
  • 12.0 contains 3 significant figures.
  • 7.11 contains 3 significant figures.

So, the solution should contain 3 significant figures.

  • Now, the issue id of rounding; In a series of calculations, carry the extra digits through to  the final result, then round.
  • If the digit to be removed is equal to or greater than 5, the preceding digit is  increased by 1.
  • The digit that should be removed is 7 that is larger than 5 so increase the preceding digit by 1.

What is the cell potential of an electrochemical cell that has the half-reactions shown below?
Karo-lina-s [1.5K]

Answer:

E°(Ag⁺/Fe°) = 0.836 volt

Explanation:

3Ag⁺ + 3e⁻ => Ag°;            E° = +0.800 volt

Fe° => Fe⁺³ + 3e⁻ ;             E° = -0.036 volt

_________________________________

Fe°(s) + 3Ag⁺(aq) => Fe⁺³(aq) + 3Ag°(s) ...    

E°(Ag⁺/Fe°) = E°(Ag⁺) - E°(Fe°) = 0.800v - ( -0.036v) = 0.836 volt

Dovator [93]

Answer:

Places where primary succession occurs include newly exposed rock areas, sand dunes, and lava flows. Simple species that can tolerate the often- harsh environment become established first. These organisms help enrich the soil, allowing other species to become established.

Image result for think about succession and the places you have seen or visited. choose one place, provide evidence from your experience, to determine whether your example showed primary or secondary succession. you can write and/or include pictures

For example, after a forest fire that kills all the mature trees on a particular landscape, grasses might grow, followed by shrubs and a variety of tree species, until eventually the community that existed before the fire is present again
