Answer:
Option C. Electrons are shared between two atoms
Explanation:
Covalent bonding is a type of bonding which exist between two non metals.
In this bonding, electrons are shared between the two atoms involved in order to attain a stable octet configuration.
This can be seen when hydrogen atom combine with chlorine atom to form hydrogen chloride as shown below:
H + Cl —> HCl
Hydrogen has 1 electron in it's outmost shell and it requires 1 electron to attain a stable configuration.
Chlorine has 7 electrons in it's outmost shell and requires 1 electron to attain a stable configuration.
During bonding, both hydrogen and chlorine will contribute 1 electron each to form bond, thereby attaining a stable configuration. The bond formed in this case is called covalent bond as both atoms involved shared electron to attain a stable configuration.
The convection current in the atmosphere is best explained as the process by which hot air expands and rises, becoming cooler and denser, then falling again in a continuous process.
Heat transfer by convection involves the transfer of heat by the actual movement of the heated molecules from the hot parts to the cooler parts of a fluid.
The continuous movement of hot air or liquid from bottom to the top and cold liquid or air from the top to the bottom is known as convection current.
Thus, we can conclude that convection current in the atmosphere is best explained as the process by which hot air expands and rises, becoming cooler and denser, then falling again in a continuous process.

Answer:
Eªcell > 0; n = 2
Explanation:
The reaction:
I2 (s) + Pb (s) → 2 I- (aq) + Pb2+ (aq)
Is product favored.
A reaction that is product favored has ΔG < 0 (Spontaneous)
K > 1 (Because concentration of products is >>>> concentration reactants).
Eªcell > 0 Because reaction is spontaneous.
And n = 2 electrons because Pb(s) is oxidizing to Pb2+ and I₂ is reducing to I⁻ (2 electrons). Statements that are true are:
<h3>Eªcell > 0; n = 2</h3>

the ingredients of the average adult,right down to the last specks of protein in your eyelashes. And even though science has given us the entire physical breakdown, there's never been a successful attempt at bringing a human to life. There's still something missing. Something scientists haven't been able to find in centuries of research. ...and in case you're wondering, all those ingredients can be bought on a child's allowance. humans can be made rather cheap. There's no magic to it.
