The electronic configuration of a ground-state Cr-atom :
1s²2s²2p⁶3s²3p⁶4s²3d⁴
<h3><u>What are electronic configurations?</u></h3>
The arrangement of an atom's or molecule's (or other physical structure's) electrons in their atomic or molecular orbitals is known as the electron configuration in atomic physics and quantum chemistry. For instance, the neon atom's electron configuration is 1s² 2s² 2p⁶, which means that 1, 2 and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells.
According to electronic configurations, each electron moves individually within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants or configuration state functions are used to mathematically characterize configurations.

Answer: 1. moles
2. 90 mg
Explanation:
According to stoichiometry:
1 mole of ozone is removed by 2 moles of sodium iodide.
Thus moles of ozone is removed by = moles of sodium iodide.
Thus moles of sodium iodide are needed to remove moles of
2.
According to stoichiometry:
1 mole of ozone is removed by 2 moles of sodium iodide.
Thus 0.0003 moles of ozone is removed by = moles of sodium iodide.
Mass of sodium iodide= (1g=1000mg)
Thus 90 mg of sodium iodide are needed to remove 13.31 mg of .
Answer:
<h3>5.) B. 40g</h3><h3>6.) B. About 20g of the KC1O3 Is dissolved</h3>

300 degrees Kelvin = 300 - 273 = 27 degrees Celsius.
So what you need to do is find out how many degrees Fahrenheit that is.
F = 9/5(27) + 32
F = 48.6 + 32
F = 80.6
You are at 55oF. You need to go from 55 to 80.6 or 25.6 degrees F.
Your closest answer is B. <<<<<< Answer
It behaved as a catalyst (the acid hydrolysis )
