Scaptia (Plinthina) beyonceae, named after Beyoncé
Answer:
2.5% of $80,000=$2,000
The Smiths pay $2,000 in school taxes per year.
Explanation:
100%=$80,000
10%=$80,000(100%)/10=$8,000(10%)
5%=$8,000(10%)/2=$4,000(5%)
2.5%=$4,000(5%)/2=$2,000(2.5%)
Answer:
the second answer/option is right
The statement that describes the 3d, 4s, and 4p orbitals of arsenic (as) based on its electronic configuration and position in the periodic table is; The 3d and 4s orbitals are completely filled, and the 4p orbital is partially filled.
The electronic configuration of arsenic is given as; 1s² 2s² 2p^(6) 3s² 3p^(6) 4s² 3d^(10) 4p³.
Now we can see that in that electronic configuration the orbitals are, s, p and D.
Now, the maximum electrons for each of the 3 orbitals are;
Maximum electrons for d orbital = 10 electrons
Maximum electrons for s orbital = 2 electrons
Maximum electrons for p orbital = 6 electrons.
Now, when we compare the maximum number of electrons for each orbital to the ones in electron configuration of arsenic, it is clear from the last 3 orbitals that the 3d and 4s orbitals are completely filled while the 4p orbital is half filled or partially filled.
