What are the empirical formulas of a) ethylene glycol, a radiator antifreeze, molecular formula C2H6O2 b) peroxodisulfuric acid,
Temka [501]
<h2>The answers are CH_3O and HSO_4</h2>

Explanation:

Given -

a) The molecular formula of ethylene glycol -

    C_2H_6O_2

∴ The empirical formula of ethylene glycol will be -

    CH_3O

Given -

b) The molecular formula of per-oxo-disulfuric acid (a compound used in bleaching agents) -

    H_2S_2O_8

∴ The empirical formula of per-oxo-disulfuric acid will be -

    HSO_4

Hence, the answers are CH_3O and HSO_4.

The reaction 2X →products is a second-order reaction, and the rate constant is 8.8 × 10−3 1/M·s. If the initial concentration of
tangare [24]
Answer is: A) 124 s.
c₀ = 3 mol/L.
c₁ = 0,700 mol/L.
k = 8,8·10⁻³ 1/M·s.
Integrated second order rate law is: 1/c₁ = 1/c₀ + k·t.
k·t = 1/0,700 - 1/3.
0,0088·t = 1,095.
t = 1,095 ÷ 0,0088.
t = 124 s.
c₀ - <span>initial concentration.
c</span>₁ - <span> concentration at a particular time.
k - </span><span>the rate constant.
t - time.</span>
