Answer:
The radioactive isotopes within these brains typically record the ages of the grains-not the time when the sedimentary rock was formed, making it difficult to date using radiometric dating. The half-life of U-235 is 704 million years.
Explanation:
hope this helps but if i'm wrong then i'm sorry..
Answer:
CuCl2-Ion-dipole forces
CuSO4-Ion-dipole forces
NH3-Dipole-dipole forces
CH3OH-Dipole-dipole forces
Explanation:
Water consists of a dipole. The water molecule contains a positive end and a negative end. The positive ion attracts the negative dipole of water while the positive dipole in water interacts with the negative ion of an ionic substance. This explains the dissolution of ionic substances in water.
Copper II chloride and copper sulphate are ionic substances hence they dissolve by the mechanism described above.
Molecules consisting of dipoles dissolves by interaction of the molecule's dipoles with the dipoles in water. For example, methanol interacts with water through hydrogen bonding which is involves molecular dipoles
Answer:
an uncharged molecule (typically highly reactive and short-lived) having an unpaired valency electron.
To reduce a haloalkane, it has to be eliminated first. This is because 2 bromopropanes are a saturated compound that can not be reduced by a saturated compound. Dehydrohalogenation of the haloalkanes into the form of propene and hydrogen bromide can lead to the elimination. The propene is then reduced to propane.
Answer:
(a)57.48 percent (b) 29.45 percent
Explanation:
copper(II) bromide is 29.45 percent copper and 71.54 percent bromine. so the first element percentage composition is always the percentage composition of the compound.
that goes same with sodium hydroxide. it is 57.48 percent sodium, 40 percent oxygen, and 2.52 percent hydrogen.
