"Decaying swamps are covered with seawater" step ONLY occurs in the formation of coal.
<u>Option:</u> B
<u>Explanation:</u>
Coal production continues in regions of swampy wetlands because groundwater is near to or just above the topsoil. Because of this, organic matter is created quickly by the flora present-faster even than it can be broken down. Layers of organic matter are deposited in these areas, and then buried.
Based on the plants and circumstances present, the mechanism that produces coal varies somewhat in various areas but the ultimate method is similar. Coal production has two primary phases: peatification, and coalification. It is a solid black, readily combustible fossil fuel containing a large quantity of carbon-based material-about 50 percent of its mass.
Hypochlorous acid is a weak acid. The 
value for the dissociation of HOCl is 
Answer: 2.35 (no unit given)
Explanation:
Answer:
The correct answer is c) Electronegativity
Explanation:
The Z corresponds to the atomic number (defines the number of protons in the nucleus and also the electrons present in the atom). The Z increases from left to right in the same period, this is due to less shielding of the electrons in the last layer. Electronegativity (defined as the ability of the atoms to attract, in a covalent chemical bond, the electrons that it shares with other atoms), increases, the greater the Z (there is less distance).
Answer:
(b) manganese-51
Explanation:
Positron emission or β+ decay is emission of positron from nucleus. It is observed for the nuclides in which ratio to the neutron and the proton is low. These type of nuclides lie below band of the stability. Positron decay is conversion of proton into neutron with emission of positron.
Manganese-51 is most likely to decay by the positron emission.
The n:p ratio:
For Cr-53 is:
For Mn-51 is:
For Fe-59 is:
As stated above, positron decay occurs when n:p ratio is low.
<u>Thus, Mn-51 has the lowest n:p ratio and therefore is likely to decay by the positron emission.</u>
