Mold fossils (a fossilized impression made in the substrate - a negative image of the organism)cast fossils (formed when a mold is filled in)trace fossils = ichnofossils (fossilized nests, gastroliths, burrows, footprints, etc.)
Hopefully this helps sorry
<u>Answer:</u> The products in the given chemical reaction are 
<u>Explanation:</u>
Reactants are defined as the species which react in the reaction and are written on the left side of the reaction arrow.
Products are defined as the species which are produced in the reaction and are written on the right side of the reaction arrow.
For the given chemical equation:
The reactants of the above reaction are 
and the products are
Hence, the products in the given chemical reaction are
6.<span>Pure </span>ethanol<span> will irritate the skin and eyes and can cause some sort of poisoning to the body</span>
7.Because Methanol<span> has to first be turned into formaldehyde in the body. Humans have an enzyme called alcohol dehydrogenase, which oxidizes alcohol compounds (adds an oxygen, effectively.) If you drink a beer, the </span>ethanol<span> is converted to acetaldehyde which is a slightly </span>toxic<span> intermediate.
8.</span><span>Like </span>methanol<span>, </span>ethanol<span> is metabolized by ADH, but the enzyme's affinity for </span>ethanol<span>is 10-20 times higher than it is for </span>methanol<span>. Fomepizole is also metabolized by ADH; however, its use is limited because of high cost and lack of availability. Hemodialysis can easily remove </span>methanol<span> and formic acid.

The percent by mass of water in Na2So4 10H2O is 55.9%
calculation
% mass = molar mass of water(H2O) in Na2SO4 .10H2O/ molar mass of Na2SO4. 10H2O x100
that is mass of H2O = 10{ ( 1x2) + 16} = 180 g/ mol
mass of Na2SO4.H2O= { (2 x23)+ 32 + ( 16 x4 ) + 180 = 322 g/mol
therefore the % mass composition = 180/322 x100 =55.9 %
