(45 pts) In which reaction is carbon reduced?
Sidana [21]

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.

C_{2} H_{2}(g)  +H_{2} (g) → C_{2} H_{4}(g)

Explanation:

Electrons displacement is explained for each reaction below:

  1. +2 to +4 = loss of 2 more lectrons-------oxidation
  2. +4 throughout reaction----no exchange of electrons
  3. -4 to +4 =  loss of 4 electrons-----oxidation
  4. 0 to -2 = gain of 2 electrons-----reduction

How many milliliters of 0.121 M HCl are needed to neutralize 44.3 mL 0.274 M Ba(OH)2? Write the equation and don't forget to bal
Sergeeva-Olga [200]

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
