Answer:
C2H4 + 3O2 --> 2CO2 + 2H2O
Explanation:
For an equation to be balanced, it must have an equal number of atoms on each side. C2H4 + 3O2 --> 2CO2 + 2H2O is the only equation out of these four the fulfills this requirement.
Answer:
Both have a pH greater than 7, but NH₃ has a lower pH than KOH.
Explanation:
- Both of NH₃ and KOH are bases (can produce OH⁻), so both have a pH greater than 7.
- NH₃ is considered as a weak base (not completely ionized), while KOH is a strong base (completely ionized).
- If both NH₃ an KOH has the same concentration, KOH produces OH⁻ higher than that of NH₃.
- So, NH₃ has a lower pH than KOH.
- Thus the right choice is:
<em>Both have a pH greater than 7, but NH₃ has a lower pH than KOH.</em>
