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.

A 20.0g sample of metal with a specific heat of 5 J/(g°C) raised it's initial temperature to 40.0 when 500J heat was added. What
slavikrds [6]

The initial temperature of the metal = 35 °C

<h3>Further explanation</h3>

Heat can be formulated :

Q = m . c . ΔT

Q = heat, J

c = specific heat, J/g C

ΔT = temperature, °C

m = 20 g

c = 5 J/(g°C)

Q = 500 J

T₁ = 40 C

the initial temperature :

\tt \Delta t(T_2-T_1)=\dfrac{Q}{m.c}\\\\40-T_1=\dfrac{500}{20.5}\\\\40-T_1=5\\\\T_1=35^oC
