Factor that can be controlled changed or measured in an experiment.
Answer:
Reductio is gain of electrons, while oxdation is loss. The oxidtion states of carbon in the reaction will show either of oxidation or reduction occurrence.
→ 
Explanation:
Electrons displacement is explained for each reaction below:
- +2 to +4 = loss of 2 more lectrons-------oxidation
- +4 throughout reaction----no exchange of electrons
- -4 to +4 = loss of 4 electrons-----oxidation
- 0 to -2 = gain of 2 electrons-----reduction
Well in the technical sense, we normally establish these as solutions, but in a practical world it is common to call them solutions. Although this is all true, I refer to this beautiful item of chemistry as the sir mix a lot of chemicals
Answer:
100 mL is the volume of HCl needed to neutralize the 44.3 of Ba(OH)₂
Explanation:
This is the chemical equation:
2HCl + Ba(OH)₂ → BaCl₂ + 2H₂O
Formula for neutralization is:
Molarity of acid . Volume of acid = Molarity of base . Volume of base
0.121 . Volume of acid = 0.274 . 44.3
Volume of acid = (0.274 . 44.3) / 0.121 → 100
