Dalton gathers evidence for the existence of atoms by measuring the masses of elements after compounds are formed.
<u>Explanation</u>:
- John Dalton accumulated proof for the presence of atoms by estimating the majority of components that responded to frame mixes. All components are made out of molecules. All particles of a similar component have a similar mass, and atoms of various components have various masses. Mixes contain atoms of more than one component.
-
Dalton did numerous investigations that gave proof to the presence of particles. For instance, He researched pressure and different properties of gases, from which he induced that gases must comprise of little, singular particles that are in steady, arbitrary movement.
<u>Given:</u>
Time taken by the electromagnetic radiation, t = 33 fs
<u>To determine:</u>
The distance (d) travelled
<u>Explanation:</u>
Time taken = 33 fs (femtosecond)
1 fs = 10⁻¹⁵ s
Thus t = 33 *10⁻¹⁵ s
Speed of electromagnetic radiation = 3*10⁸ m/s
Distance = Speed * Time = 3*10⁸ ms-1 * 33*10⁻¹⁵ s = 99*10⁻⁷ m
Ans: distance traveled = 9.9*10⁻⁶ m
The different is that the galvanic cell converts chemical energy into the electrical energy and the electrolytic cell coverts electrical energy into chemical energy
Answer:
The rule is especially applicable to carbon, nitrogen, oxygen, and the halogens, but also to metals such as sodium or magnesium. ... All four of these electrons are counted in both the carbon octet and the oxygen octet, so that both atoms are considered to obey the octet rule.
