THE ORDER IS
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p, 8s. Although this looks confusing, there is an easy way to remember. Go in order of the lines from top to bottom, top
Answer:
A. 2 chlorine (Cl) atoms
Explanation:
2 chlorine atoms means that chlorine is a gas.
Sodium (Na) reacts with 2 chlorine atoms according to the equation below;
Na(s) + Cl2(g) => NaCl2
Answer:
F2(g)/HF(aq)>Co3 (aq)/Co2 (aq)> H2O2(aq)/H2O(l)> PbO2(s)/Pb(s)>Br2(l)/Br-(aq)
Explanation:
The tendency of any specie to function as oxidizing agent is a highly dependent on the reduction potential of the couple. The more positive the value of the reduction potential of the couple, the better it does as an oxidizing agent.
This implies that we could know a good oxidizing agent by looking at their respective reduction potentials. The couple having the greatest (most positive) reduction potential is selected as the best oxidizing agent. If there are a number of couples at having different reduction potentials, the order of oxidizing ability can be obtained by arranging the species in order of decreasing positive reduction potentials just as we have done in the answer above.
The chemical bond is determined by its overall shape of
the molecule, the angles made by the lines joining the nuclei of the atoms in
the molecule. The bond angles together with the bond lengths accurately define
the shape and size of the molecule.
The ratio that show the relationship between moles of each reactant and product in the reaction that is
N2 + 3 H2 = 2NH3
the ratio is as follows
1mole N2 : 3 mol H2 :2mol NH3
This ratio is from equation since there is 1 mole of N2 reacted with 3 moles of H2 to produce 2 moles of NH3
