IRINA_888 [86]
C4H10 is a saturated hydrocarbon or alkane with the general formula CnH(2n+2). Since n = 4 for C4H10, the prefix is but-, and this compound is butane. The rest of the substances are common compounds: oxygen, carbon dioxide and water, so the word equation is:

Chemistry!! Please help
m_a_m_a [10]

Answer:

5.3 × 10⁻¹⁷ mol·L⁻¹

Explanation:

Let <em>s</em> = the molar solubility.

                Cu₂S(s) ⇌ 2Cu⁺(aq) + S²⁻(aq); K_{sp} = 6.1 × 10⁻⁴⁹

E/mol·L⁻¹:                        2<em>s</em>             <em>s </em>

K_{sp}  =[Cu⁺]²[S²⁻] = (2<em>s</em>)²×<em>s</em> = 4s^3 = 6.1 × 10⁻⁴⁹

s^{3}= \frac{6.1 \times 10^{-49}}{4} = 1.52 \times 10^{-49}

s = \sqrt[3]{1.52 \times 10^{-49}} \text{ mol/L} = 5.3 \times 10^{-17} \text{ mol/L}
