Inner planets are rockier and outer planets are gaseous. Hope this helps! Can I have brainliest please
In all atoms, the number of protons and the number of electrons is always the same. The number of neutrons is very roughly the same as the number of protons, but sometimes it's rather more. The number of protons in an atom is called the atomic number and it tells you what type of atom you have.
Answer:
D
Explanation:
Hello!
Since the rate must have the following units: mol/(L*s), the suitable units for k, considering that the term [D] [X] leads to mol^2/(L^2) (it means a second order kinetic law), are L/(mol*s), nevertheless, that answer isn't in the given options.
Answer:
Q = 1360.248 j
Explanation:
Given data:
Mass of brass = 298.3 g
Initial temperature = 30.0°C
Final temperature = 150°C
Specific heat capacity of brass = 0.038 J/g.°C
Heat absorbed = ?
SOLUTION:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 150°C - 30.0°C
ΔT = 120°C
Q = 298.3 g × 0.038 J/g.°C × 120°C
Q = 1360.248 j
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.
