Объяснение:
1. K °-1e = K⁺¹ катион
S° +2e = S⁻² анион
2. М (Cl₂) = 35,5*2=70 г/моль
N (Cl₂) = M/ a (число авагадро) = 70/ 6,022*10⁻²³ = 11,62 * 10⁻²³ грамм
Далее используем так же эту формулу
M (CO₂)= 12+16*2= 12+32=44 г/моль
N(CO₂) = 44/ 6.022*10⁻²³= 7.31*10⁻²³грамм
M (NaI) = 149 г/моль
N (NaI) = 149 / 6,022*10⁻²³= 24,74 * 10 ⁻²³
1. М (Н₂О) = 16+2 = 18 г/моль
3 М (Н₂О) = 3*18 = 54 г/моль
N (Н₂О) = 54/6,022*10⁻²³ = 8,97*10⁻²³ грамм
2. n (СaO) = m/M= 560/40 = 14 моль
3. n = m/M
n (N₂) = 5.6 / 28= 0.2 моль
V = n*22.4
V(N₂) = 0.2*22.4 = 4.48 л
