Answer:
Four covalent bonds.
Explanation:
Hello,
In this case, given the attached picture in which you can find the Lewis dot structure for metanal (formaldehyde) we can see two C-H bonds and two C-O bonds via a double bond, thus, we can compute the type of each bond given the electronegativities of hydrogen, carbon and oxygen which are 2.1, 2.5 and 3.5 respectively:
Thus, since both electronegativity difference are less 1.7 we infer that all of them are covalent, therefore, it has four covalent bonds, two C-H bonds and a double C-O bond.
Best regards-
Answer: 2
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of are produced by = 4 moles of
Thus 1.18 moles of will be produced by=
of
Mass of
Thus 85.0 g of will be required and 2 steps are required to get the answer.
