Question

K2O=KOH=KCL=KNO3=K3PO4=K2SO4​

Answer 1

Ответ:

1) 1. 2K + O2 = K2O2

K2O2 + 2K = 2K2O

2. K2O + 2H2O = 2KOH +H2

3. 2KOH + H2SO4 = K2SO4 + 2H2O

2) 4Al(0) + 3O2(O) = 2Al2O3(+3;-2)

в-ль Al(0) - 3e = Al(+3) o-e

о-ль O2 (0) + 4e = 2O(-2) в-е

С2H6(-3;+1) = 2C(0) + 3H2(0)

в-ль С (-3) - 3е = С (0) о-е

о-ль 2H(+1) + 2е = H2(0)

Ca(0) + H2SO4(+1;+6;-2) = CaSO4(+2;+6;-2) + H2(0)

в-ль Ca(0) - 2е = Сa(+2) о-е

о-ль 2H(+1) + 2е = H2(0)

2Fe(0) + 3CL2(0) = 2FeCL3(+3;-1)

в-ль Fe(0) - 3e = Fe(+3) о-е

о-ль СL2(0) + 2e = CL(-1) в-е

3) SiF4 (+4;-1) P2O3 (+3;-2) CS2(+4;-2) C(0) K2MnO4 (+1;+6;-2) CuCO3 (+2;+4;-2) NaOH (+1;-2;+1) Mg (0)

Answer 2

K2O=KOH=KCl=KNO3=K3PO4=K2SO4

The equation you provided represents the equal molar ratios between potassium oxide (K2O), potassium hydroxide (KOH), potassium chloride (KCl), potassium nitrate (KNO3), potassium phosphate (K3PO4), and potassium sulfate (K2SO4). This means that for every one mole of any of these compounds, there is an equal number of moles of the other compounds in the equation.

It's important to note that this equation does not represent a chemical reaction but rather an equivalence between these compounds. Each compound has its own unique properties and uses.
