Question

K-koh-k2so4-kcl-kno3

Answer 1

1) 2K + 2H2O -> 2KOH + H2

2) 2KOH + H2SO4 -> K2SO4 + 2H2O

Ионный вид: OH (-) + H (+) -> H2O

3) K2SO4 + BaCl2 -> 2KCl + BaSO4 (Осадок)

Ионный вид: Ba (2+) + SO4 (2-) -> BaSO4 (в осадок)

4) KCl + AgNO3 -> AgCl (осадок) + KNO3

Cl (-) + Ag(+) -> AgCl (осадок)

Answer 2

The sequence "K-koh-k2so4-kcl-kno3" appears to be a combination of chemical symbols and compounds. Let's break it down:

1. "K" represents the chemical symbol for potassium.
2. "OH" represents the hydroxide group, which typically combines with metal cations to form metal hydroxides.
3. "K2SO4" represents potassium sulfate, which is a compound composed of two potassium ions (K+) and one sulfate ion (SO4^2-).
4. "KCl" represents potassium chloride, which is a compound composed of one potassium ion (K+) and one chloride ion (Cl-).
5. "KNO3" represents potassium nitrate, which is a compound composed of one potassium ion (K+) and one nitrate ion (NO3-).

In summary, the sequence "K-koh-k2so4-kcl-kno3" refers to the elements potassium (K) and compounds such as potassium hydroxide (KOH), potassium sulfate (K2SO4), potassium chloride (KCl), and potassium nitrate (KNO3).
