1. at the surface of the Atlantic Ocean
2. blue
D. Pressure vs. temperature
<u>Explanation:</u>
In physical chemistry, this diagram or graph is utilized to predict the conditions like volume, pressure and temperature at which thermodynamic- ally different phases like solid, gases and liquid occur and both states exist at equilibrium.
The simple phase diagrams are the pressure–temperature diagrams of a simple substance like water. In that diagram, x and y axes were correspond to the temperature and pressure. It shows, in the space of pressure and temperature, the equilibrium lines occur between all the 3 phases of water.
"Taconian orogeny" mountain-building event occurred in New York State during the time when Valcouroceras was living in oceans covering parts of New York State.
<u>Option: C</u>
<u>Explanation:</u>
A timeframe of mountain construction, which ended 440 million years earlier is known as the Taconic orogeny. A tremendous network of mountains developed from eastern Canada down to what is today the US East Coast Piedmont.
As the mountain range deteriorated during the Silurian and Devonian periods, sediments from the mountain range dispersed across the Appalachians and midcontinental North America of today. It took place when a terrane or sequence of terranes i.e volcanic arcs and microcontinents collide with east North America in a subduction zone that dips east.
Since neon has 8 valence electrons, a full octet makes neon stable. It is also a noble gas. Then, you do the configuration...
1s2 2s2 2p6
2s holds 2 valence electrons while 2p has 6 that equals a full octet.
