Enter your answer in the provided box.
Lina20 [59]

Answer:

5.06atm

Explanation:

Using the combined gas law equation;

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (Litres)

V2 = final volume (Litres)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information provided in this question;

P1 = 1.34 atm

P2 = ?

V1 = 5.48 L

V2 = 1.32 L

T1 = 61 °C = 61 + 273 = 334K

T2 = 31 °C = 31 + 273 = 304K

Using P1V1/T1 = P2V2/T2

1.34 × 5.48/334 = P2 × 1.32/304

7.34/334 = 1.32P2/304

Cross multiply

334 × 1.32P2 = 304 × 7.34

440.88P2 = 2231.36

P2 = 2231.36/440.88

P2 = 5.06

The final pressure is 5.06atm

Calculate the volume of water which was liberated during the decomposition of hydrogen peroxide.
nikitadnepr [17]

The answer is :

The normal equation for the decomposition of hydrogen peroxide indicates that 2 vol. peroxide vapor should give rise to 2 vol. water vapor and 1 vol. oxygen.

What is hydrogen peroxide ?

  • Hydrogen peroxide is water (H2O) with an extra oxygen molecule (H2O2).
  • The extra oxygen molecule oxidizes, which is how peroxide gets its power says Dr. Beers.
  • This oxidation kills germs and bleaches color from porous surfaces like fabrics.
  • Hydrogen peroxide is found in biological systems including the human body.
  • Enzymes that use or decompose hydrogen peroxide are classified as peroxidases.

True

Explanation:

Harry Hess in 1961 resurrected Wegener's continental drift hypothesis and also he mantle convection idea of Arthur Holmes by postulating the theory of sea floor spreading.

  • After Wegener's postulation of the continental drift hypothesis, not much was done.
  • It was only around 1931 that Arthur Holmes came up with the idea of a convecting mantle.
  • After the second world war passed, new instruments were used to investigate and map the ocean floor.
  • Through this, Arthur Holmes came up with the idea of a spreading sea floor.
  • This gave a full gleam picture to the idea of a moving earth and the more accepted terminology of "Plate tectonics " came to the fore.
