During the nineteenth century, biologists knew that South America and Africa contained similar fossils. These fossils led them t

o believe that a temporary land bridge between South America and Africa allowed
ancient species to move between both continents. In the twentieth century, evidence showed that South America and Africa were once part of the same larger continent and that there were no land bridges
between them. How should biologists respond to the new geological finding?

A) Biologists should reject the geological finding, because it is new.
B) Biologists should ask physicists what to do, because physics is a more exact science.
C) Biologists should reject the belief in ancient species, because there were no land bridges.
D) Biologists should update the history of life, because it should include the new geological finding.

A 4.0 L balloon has a pressure of 406 kPa. When the pressure increases to 2,030 kPa, what is the volume? *
elena-14-01-66 [18.8K]

The new volume when pressure increases to 2,030 kPa is 0.8L

BOYLE'S LAW:

The new volume of a gas can be calculated using Boyle's law equation:

P1V1 = P2V2

Where;

  1. P1 = initial pressure (kPa)
  2. P2 = final pressure (kPa)
  3. V1 = initial volume (L)
  4. V2 = final volume (L)

According to this question, a 4.0 L balloon has a pressure of 406 kPa. When the pressure increases to 2,030 kPa, the volume is calculated as:

406 × 4 = 2030 × V2

1624 = 2030V2

V2 = 1624 ÷ 2030

V2 = 0.8L

Therefore, the new volume when pressure increases to 2,030 kPa is 0.8L.

Để pha 2 lít dung dịch H2SO4 0,1N từ axit đặc 98% (d 1.84g/ml). Cần lấy bao nhiêu ml acid đặc
Ivanshal [37]

Answer:

Cm = Cn/n = 0.1/2 = 0.05 (M)

n = 0.05*2= 0.1 mol

m H2SO4= 0.1*98= 9.8 g

m dd H2SO4= 9.8/ 0.98 =10 g

V= 10/ 1.84 = 5.435 ml
