Answer is: one electron in the first three orbitals, none in the fourth or fifth orbitals. All three electrons will have parallel spins (unpaired electrons).
This is Hund's rule - orbitals of the same energy are each filled with one electron before filling any with a second, these first electrons have the same spin.
Answer: The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds.
Hope this helps............ Stay safe and have a Merry Christmas!!!!!!! :D
Answer:
1. 1.100x10⁴mg
2. 2444mg
Explanation:
1. The 18.00g milk chocolate bar contain 11.00g of sugar. In miligrams:
11.00g * (1000mg / 1g) = 1.100x10⁴mg
2. If a bar of 18.00g contain 11.00g of sugar, a bar of 4.000g will contain:}
4.000g bar * (11.00g / 18.00g) = 2.444g of sugar.
In miligrams:
2.444g * (1000mg / 1g) = 2444mg
Answer is: the oxidation number of oxygen must decrease.
Oxidizing agent is element (substance) that gain electrons in chemical reaction.
For example, balanced chemical reaction: C + O₂ → CO₂.
Oxygen change oxidation number from 0 to oxidation number -2 (reduction) and carbon change from 0 to +4 (oxidation)
Answer:
c . a proton
Protons and neutrons have approximately the same mass, about 1.67 × 10−24 grams
