Hydropower is one of the oldest renewable resources and has been used for thousands of years.
Answer:
From the solubility curve, which salt shows the least change in solubility as the temperature increases? NaCl
Explanation:
Amino acids are the basic parts of proteins
Answer:
He developed the concept of concentric electron energy levels
Explanation:
Before Bohr's model, Rutherford's model was proposed. This model explains most of the properties of the atom but failed to explain the stability of the atom.
As per Rutherford's model, electrons revolve around the nucleus in the orbit.
But revolving electron in their orbit around nucleus would give up energy and so gradually move towards the nucleus and therefore, eventually collapse.
Bohr's proposed that the electrons around the nucleus move orbit of fixed energy called "stationary states". Electrons in these stationary states do not radiate energy.
Therefore, proposal of concentric electron energy levels refine the atomic models.
Bronze metal is harder and more malleable than copper. It is also conducts property of ductility, so it can be easily shaped as a statue.
