There is 78% of nitrogen in the air so i guess you breathe in 78% of nitrogen in the air
Answer:
dispersion.
Explanation:
The molecule, PF2Cl3 is trigonal bipyramidal. The dipoles in the molecule cancel out since there is a symmetric charge distribution around the molecule hence the resultant dipole moment of the molecule is zero.
If the molecule is nonpolar, then the dominant intermolecular forces present are the weak dispersion forces, hence the answer above.
Polar compounds can dissolve in polar substances and Will not dissolve in non polar substances and same non polar substances will dissolve only in non polarsubstances .
e.g. Sodium chloride is a polar compound that'll dissolve in water ( polar solvent) and the same substance(NaCl) won't dissolve in cyclohexane ( A non polar solvent)
Answer:
the fourth one or the first, but I wouldn't say I'm completely sure.
Explanation:
2KClO₃ = 2KCl + 3O₂
n(KClO₃)=2 mol
n(O₂)=3/2 *n(KClO₃)
n(O₂)=1.5 *2 mol = 3 mol
3 moles of oxygen are produced
