Answer: There is a single covalent bond in a chlorine molecule.
Explanation: The chlorine molecule is represented as Cl−Cl, i.e. C
l2. Between the chlorine atoms, 2 electrons overlap to form a region of high electron density to which the positively charged chlorine nuclei are attracted, such that internuclear repulsion is negated and a net attractive force results. Because the bonding electrons are shared between the nuclei, we conceive that each atom has 8 valence electrons.
Of course, on reaction with sodium, the sodium reduces the chlorine molecule to give 2×Cl−. The resultant bond between Na+ and Cl−is ionic and a non-molecular substance results.

Answer:
The plasmodial slime molds are the kind of protist that can live in groups in which different individuals perform different jobs. Some kinds of bacterial cell walls also have other functions.
Answer:
In thioformaldehyde molecule,
Central atom - C
lone pairs on central atom - zero
Ideal bond angle between the carbon -hydrogen bonds - 
Compared to the ideal angle, you would expect the actual angle between the carbon-hydrogen bonds to be
.
Explanation:
The structure of thioformaldehyde is as follows. (in attachment).
From the structure,
Central atom - C
There is no lone pairs are present on the carbon atom, Hence,lone pairs on central atom - zero
The geometry of thioformaldehyde is Trigonal planar.
Hence, the ideal bond angle is
.
Ideal bond angle between the carbon -hydrogen bonds - 
All bonds in the thioformaldehyde is similar. Therefore,actual angle between the carbon-hydrogen to be
.
Answer:
Al ==> Al^3+ + 3e
Pb^2+ + 2e ==> Pb
Oxidation is the loss of electrons. Reduction is the gain of electrons. Which half rxn above lost and which gained?
For the potential of the cell, look up the reductions potentials, change the sign of the Al half cell, add in the potential for the Pb and add them.
