Answer
B salt this is beacause salt is made of monomers
Answer:
2,4,2
Explanation:
by looking at the subscripts (small number behind the element) you can tell how many of these atoms are presented in the compound.
your compound is C2H4O2
so there are two carbon atoms present, four hydrogen atoms present, and 2 oxygen atoms present.
hope this helps :)
1) The amount of PbS produced will be 16.27 grams
2: The amount of Fe produced will be 118.72 grams.
<h3>Stoichiometric problems</h3>
1) The equation is balanced. The mole ratio of lead (II) acetate to the PbS is 1:1.
Mole of 22.11 lead acetate = 22.11/ 325.29 = 0.06797 moles
Equivalent mole of PbS = 0.06797 moles
Mass of PbS = 0.06797 x 239.3 = 16.27 grams
2) from the equation, the mole ratio of Al to Fe is 1:1.
Mole of 57.2 g Al = 57.2/26.98 = 2.12 moles
Equivalent mole of Fe = 2.12 moles
Mass of Fe = 2.12 x 56 = 118.72 grams.

<span>the molar mass of H2O can be calculated with the following method:M(H2O)=2x M(H) + M(O), that is because we know that M(H)=1g/mol, M(O)=16g/mol, so M(H2O)=2x1+16=18g/mol, that means 1 mole of H2O contains 18g, so finally one mole of H2O correspond to 18 grams.</span>
A covalent bond is on in which electron pairs are shared between one or more electron pairs between atoms. Polar covalent bonds are so called because the electron density is closer to one atom participating in the bond than to another. The tendency of electron density to be closer to one atom and not the other can be due to the geometry of the bond.
