Eh I can't comment
That's y
No-one knows that I enter this site
Only a cousin knows
Cz I've got a protective family lol
Answer:
Silver ions 1 Hydrogen ions 2 Iron ions 3 Sodium ions 4
Explanation:
Use the ideal gas law PV = nRT and manipulate it to solve for n. PV/RT = n.
Convert to SI units:
660ml -> 0.660 L
27 degrees -> 300 K
Leave Pressure as is
Use 62.36368 for R becuase you are using mmHg for Pressure.
Now plug into the equation to get about 0.025928 mols. Divide the 3.30 grams by the mols to get about 127 g/mol.
here we have to explain the development of the atomic theory by the atomic emission spectrum.
The most important aid in determining the structure of an atom has been study of radiation emitted and absorbed by the elements. The glowing atoms of an element emit radiations.
These are called the atomic spectra. This study helped to understand the structure of the atoms.
To explain the atomic spectra the Bohr's model was introduced. The postulates of the Bohr's model explain the fine spectrum of the atom up to the particle nature of the electrons.
Later some modification on the Bohr's postulates was made to explain the wave nature of the electrons as well. But the atomic spectra is best be understood by the Bohr's atomic model which developed the atomic theory.
Thus the understanding of emission spectrum of atom to develop the atomic theory is explained.
Answer: Positive charge
Explanation:
An atom consists of electron (negatively charged), Proton (Positively charged) and neutron (no charge).
The proton (+) and the neutron (no charge) are in the nucleus of the atom. this makes the resulting charge of the nucleus positive while electron (-) is outside the nucleus.
