Answer:
HCl conc.= 6.0mol/L
Explanation:
From the dissociation of HCl= 1 mole H+ and 1mol Cl-, which is equivalent stoichiometrically in concentration to that of 1 mol HCl,
Answer:
• Molecular mass of Iron (III) tetraoxide
[ molar masses: Fe → 56, O → 16 ]
Answer:
Thermal energy
Explanation:
When gasoline, coal, batteries and logs are all burn they transform chemical energy to thermal energy.
The chemical energy is the energy held between chemical chains and bonds within an atom.
- When they combust, they release thermal energy
- Chemical energy is a potential energy.
- The thermal energy is a kinetic energy
- It increase the average motion of the particles in the medium
- The breaking bond when produces heat which is a form of thermal energy.
