Answer:
2.52 x
J
Explanation:
The energy given off by the microwave can be determined by the application of Planck's energy formula:
E = hf
where: E is the required energy, h is Planck's constant (6.626 x 
Kg/s), and f is the frequency (3.8 x
Hz).
So that;
E = 6.626 x
x 3.8 x 
= 2.51788 x 
Therefore, the energy released by the wave is 2.52 x
J.
Answer: concentration of solutions are expressed in various ways mol/L, mol/dm3, g/L etc
Explanation:
Answer : The lewis dot structure includes the lone pair of electrons in any element and is helpful for defining the bond formation using the electrons.
