Can you make the picture clearer please or tell me what I’m supposed to do in comments?
Zinc
Explanation:
Electron configuration:
1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s²
To decipher this atom, we must understand what each of the letters and number represents;
1s²
1 is the principal quantum number
s is the azimuthal number or the subshell
2 superscript is the number of electrons
Using the number of electrons, we can deduced the atom:
2+2+6+2+6+10+2 = 30 electrons
The element with 30 electrons on the periodic table is Zinc

Answer:
3.481 x 10²⁴ atoms
Explanation:
Data Given:
Number of moles of NH₄NO₃ = 5.78 mol
Number of atoms of NH₄NO₃ = ?
Solution:
Formula used
no. of moles = no. of atoms / Avogadro's number
As we have to find no. of atoms
So, we have to rearrange the above equation
no. of atoms = no. of moles x Avogadro's number . . . . . (1)
Where
Avogadro's number = 6.022 x 10²³ atoms
Put values in above Equation 1
no. of atoms = 5.78 mol x 6.022 x 10²³ atoms/mol
no. of atoms = 3.481 x 10²⁴ mol
So,
no. of atoms in 5.78 mole NH₄NO₃ = 3.481 x 10²⁴ atoms
2 resonance structure.
O=S⁺-O⁻ and O⁻-S⁺=O, angles between S and O are 120°, bond order is 1,5.
Answer: During the day, a typical greenhouse will trap Infrared photons from the sun, which allows the plants inside to stay warm at night. ... The much needed sunlight will still come through but the extra layer of protection will keep your plants safe at night
