Answer:
0.725 moles
Explanation:
Use the mole = mass/mr equation to find the moles.
Mole = 14.5/20 (Neon's Mr) = 0.725 Moles
Answer:
The correct answer is marsh.
Explanation:
A kind of wetland that generally gets formed in the transition regions between the aquatic and the terrestrial ecosystems is termed as the marsh. Different kinds of birds and animals are found within a marshland, and various herbaceous species like reeds and grasses are found in the marshy regions.
The formation of marshes generally takes place close to the streams or lakes, and as all the mentioned characteristics resemble the wetland pictured by Samantha in the given question, thus, the kind of wetland in which Samantha was most likely in is marsh.
Answer:
[Ne] 3s² 3p²
Explanation:
Silicon atoms have 14 electrons. The ground state electron configuration of ground state gaseous neutral silicon is 1s²2s²2p⁶3s²3p².
Using noble gas shorthand, the electronic configuration is reduced to;
[Ne] 3s² 3p². Ne s the nearest noble gas to silicon, Ne contains 8 electrons, this means there's still 4 more electrons to fill. The s orrbital can only hold 2, hence the reaing two is transferred to the p orbital.
