Answer:
2Fe + 8HCl =2 HFeCl4 + 3H2
Explanation:
Fe + HCl = HFeCl4 + H2
1Fe 1Fe
1H 3H
1Cl 4CL
2Fe + 8HCl =2 HFeCl4 + 3H2
2Fe 2Fe
8H 8H
8Cl 8CL
Answer:
MgCl2 + H2O
Explanation:
i dont know how to explain but i believe that correct
Answer: A diode laser which emits at a wavelength of 988 nm is in the infra-red portion of electromagnetic spectrum.
Explanation:
Electromagnetic spectrum shows the wavelength or frequency ranges of different electromagnetic radiations. According to this spectrum, the range for infra-red region is from .
Therefor, a diode laser which emits at a wavelength of 988 nm is in the infra-red portion of electromagnetic spectrum.
Answer:
Option B
Explanation:
The image for the question is attached herewith
Solution
The curve B represents gas curve at room temperature while C represents the gas curve for hot temperature and curve A represents gas curve for gas at cold temperature
The number of particles in hot gases are sparsely distributed and the energy of particles is high as compared to the energy of particles at room temperature and cool temperature.
Hence, option B is correct
Thermal energy<span> is the total kinetic </span>energy possessed by the system. Heat<span> is an </span>energy<span> in transit, when there a is temperature difference </span>between<span> two systems.</span>
