Answer:
0.5 moles of O₂
Explanation:
See the stoichiometry of the reaction:
2CO + O₂ → 2CO₂
2 moles of carbon monoxide need 1 mol of oxygen to react in order to produce 2 moles of carbon dioxide.
If I want to produce 1 mol of CO₂, I just need the half of O₂.
You will see in this rule of three. Ratio is 2:1
2 moles of CO₂ are produced by 1 mol of O₂ (Stoichiometry - reaction)
1 mol of CO₂ will be produced by ( 1 . 1) / 2 = 0.5 moles
Answer:
Protons, neutrons, electrons..
Explanation:
Protons and neutrons consist of quarks which are stuck together by tiny things called gluons.
Hope this helps! :)
In CH4, C has no lone pairs, the electron density is zero since it is equally distributed.
in CH3OH, O has 2 lone pairs.
In PH2F, F has 3 lone pairs
In NOH, N has 1 lone pair, in this case, oxygen has more lone pairs than N as such the electron density of oxygen is higher than that of nitrogen.
*Reference pictures to see how they each connect.
Answer:
Dipole-dipole attractions
Explanation:
PBr₃ is a <em>trigonal pyramidal</em> molecule.
The P-Br bonds are polar, with their bond dipoles pointing toward the Br atoms (see below).
The x-components of the dipoles cancel, but the y-components reinforce each other.
The partially negative Br atoms are attracted to the partially positive N atoms in neighboring molecules.
These dipole-dipole forces are the strongest intermolecular forces in PBr₃.
