It would be potassium chloride or kcl
The answer to this question would be C
Answer:
when naming ionic compounds — those are only used in naming covalent molecular compounds. Do NOT use prefixes to indicate how many of each element is present; this information is implied in the name of the compound. since iron can form more than one charge. Ionic Compounds Containing a Metal and a Polyatomic Ion.
Answer: This is an oxidation-reduction (redox) reaction:
3 C-II - 12 e- → 3 CII (oxidation)
4 CrVI + 12 e- → 4 CrIII (reduction)
C2H5OH is a reducing agent, K2Cr2O7 is an oxidizing agent.
Answer:
2.00 M
Explanation:
The concentration of a solution is given by

where
m is the mass of solute
V is the volume of the solution
At the beginning, the solution has:
M = 6.00 M is the concentration
V = 100 mL = 0.1 L is the volume
So the mass of solute (HCl) is

Then, the HCL is diluted into a solution with volume of
V = 300 mL = 0.3 L
Therefore, the final concentration is:
