Answer:
specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity.
Explanation:
Answer: I think the answer is C. NaCl and H2O
Explanation: I’m not sure tho
Chemical nomenclature, replete as it is withcompounds with complex names, is arepository for some very peculiar and sometimes startling names. A browse through the Physical Constants of Organic Compounds in the CRC Handbook of Chemistry and Physics (a fundamental resource) will reveal not just the whimsical work of chemists, but the sometimes peculiar compound names that occur as the consequence of simple juxtaposition. Some names derive legitimately from their chemical makeup, from the geographic region where they may be found, the plant or animal species from which they are isolated or the name of the discoverer.
B= CH2O
empirical formula using the simplest ratio of atoms in the compound
Answer:
Explanation:
Suppose an electron makes transition from n initial (ni) to n final (nf) then formula for wavelength is given by,
Where,
- λ is wavelength of photon
- Rʜ is rydberg constant, the value of Rʜ is
109690 Cm-¹ in <em>Puri Sharma Pathania</em> standard book of physical chemistry &
109737 Cm-¹ according to <em>Wikipedia</em>
- Z is the atomic number of atom, for hydrogen Z =1,
& according to given data, ni = 5, nf = 3
Solution:
Let's solve for wavelength,
Substituting all the given data in above formula,
Now we know that, 1 cm = 10000000 nm,
Converting the wavelength from Cm → Nm
