In order to determine, Order of reaction, we have to add all the exponents written in the Chemical form, on the Reactant species.
Hope this helps!
No. Of protons = mass no. - no. Of neutrons
No. Of protons = 67 - 37
= 30
No. Of electrons = 28
Zinc will have 30 protons and 28 electrons. So, it will have +2 charge
Symbol - Zn^+2
In a chemical formula, subscripts indicate the elements' ratio. Changing the subscripts would change the identity of the chemical. For example CO2 = carbon DIoxide, but CO = carbon MONoxide.
Hey i think the right answer is -
C. By frequency on the electromagnetic spectrum
i hope it helps !
The statement above is TRUE.
Lord Kelvin contributed to science during his life time by describing the concept of absolute zero and providing explanation for thermal energy change process. Lord Kelvin was a physical chemist who investigated how matter behave on a molecular and atomic level and how chemical reactions occur.<span />
