Answer: True
Explanation: As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense.
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
Answer:
Covalent bonding
Explanation:
Covalent bonding is the bond that holds all compound that are formed by carbon.
It is a very strong intermolecular bond that holds the structure of carbon compounds in place.
Principally, covalent compounds are formed by sharing of electrons between contributing atoms.
Covalent bonds are the strongest bond types. A reason for this conclusion can be see in case of diamond. Here, there is a covalent linkage between the atoms present and the strength of these bonds is responsible for how strong the diamond crystal is
Answer:
Alternative C would be the correct choice.
Explanation:
- The dual compounds were evaluated on something like a TLC plate through three separate additives in conducting a TLC study of ferrocene versus acetylferrocene.
- The polar as well as nonpolar ferrocene where nonpolar is about 0.63 with the maximum
value, and indeed the polar is somewhere around 0.19 with
. - TLC plate (30:1 toluene/ethanol) established with.
The other three choices are not related to the given circumstances. So that option C would be the appropriate choice.
