Answer:
Evaporated via combustion.
Explanation:
The loss on ignition (LOI) and Ash content are inorganic analytical techniques used to determine the percentage by mass of hydrocarbon in compounds. This process allows volatile matter and possibly impurities found in a material to evaporate, leaving behind the true chemical constituents of the material.
The 10kg lost could be moisture content of the tree, or other volatile matter which has escaped on combustion of the tree.
Answer:Specific gravity, also called relative density, is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.
Explanation:
<span>P<span>F5
</span></span><span> has a zero dipole moment as it doesn't have a lone pair of electrons. the geometry is trigonal bipyramidal. The axial P-F bonds "cancel" each other. The equatorial P-F bonds are oriented as trigonal planar, so those three (like in BF3) "cancel" as well.

Dipole moment of a compound is different from the dipole moment of a bond. You need to look at ALL bonds for the overall dipole moment of a molecule.
The reason why Br has a greater magnitude of electron affinity than that of I is that there is a greater attraction between an added electron and the nucleus in Br than in I.
In the periodic table, there are trends that increase down the group and across the period. Electron affinity is a trend that increases across the period but decreases down the group.
Recall that the ability of an atom to accept an electron depends on the size of the atom. The smaller the atom, the greater the attraction between an added electron and the nucleus.
Since Br is smaller than I, there is a greater attraction between an added electron and the nucleus in Br than in I which explains why Br has a greater magnitude of electron affinity than I.

Alter means change. So when a wave hits a big rock, the rock sheds a tiny bit, creating sand.
