The early ideas of the atom states that the indivisible object is hollow or is a solid object with nothing inside. The later discoveries or works of the scientists states that inside the atoms are the subatomic particles which are the electrons, protons, and neutrons.
Answer:
the answer is C
Explanation:
This is because group6 elements are diatomic and when they are chemically combined their subscript 2 cancels out
Answer:
Environment refers to everything that surrounds an individual and interacts between them. The factors that control the environment can be biotic and abiotic.
Humans have greatly affected the environment. Some of the ways in which the environment is affected by humans are as follows-
(1) Humans have constructed industries and factories that have released a huge amount of toxic gases into the atmosphere.
(2) These harmful gases have increased the earth's global temperature. As a result of which the global warming effect has increased.
(3) The waste materials eliminated from these industries mix with the rivers and streams and pollute the water. It degrades water quality.
(4) The fossil fuels are exhausted at a very high rate.
(5) The spilling of the oils in the oceans has affected the marine species drastically.
(6) Due to the extensive mining at different places, soil fertility has decreased considerably.
(7) Cutting down trees for settlement purposes and other infrastructures.
Answer :
The Nernst equation :
![E_{cell}=E^o_{cell}-\frac{2.303RT}{nF}\log \frac{[Anode]}{[Cathode]}](https://tex.z-dn.net/?f=E_%7Bcell%7D%3DE%5Eo_%7Bcell%7D-%5Cfrac%7B2.303RT%7D%7BnF%7D%5Clog%20%5Cfrac%7B%5BAnode%5D%7D%7B%5BCathode%5D%7D)
where,
= standard cell potential
n = number of electrons in oxidation-reduction reaction
F = Faraday constant = 96500 C
R= gas constant = 8.314 J/Kmol
T = temperature
[Anode] = anodic ion concentration
[Cathode] = cathodic ion concentration
