Answer:
conductivity in water/ solid state
Explanation:
becuase, they both dissolve in water the same, therofre it is the least helpful.
Answer: loss of nutrients
Explanation:
the quarry was dug up and vegetation started dyeing. the quarry was probably rich with nutrients.
Answer:
sp2
Explanation:
Orbital hybridization is defined as the changes in the orbitals of atoms when they pair with electrons of other atoms to form chemical bonds.
C atoms in C2Cl4 or tetrachloroethene have a total of three bond pairs, two with each chlorine atom and one with other carbon atom and zero lone pairs. Thus, C atoms in C2Cl4 is sp2 hybridized.
Hence, the correct answer is "sp2".
Answer:
The balance equation is
→ 
Explanation:
first, we have to make sure that the atoms are balanced
→ 
→ 
then we proceed to balance charges of each half-reaction
→
→ 
Now we multiply the half-reactions to match the number of electrons in each one
( → )x2
( → )x3
and now we do the sum of the half-reactions
2
→ 2
→ 3 
→
note: the only atom that needed to be balanced was I
