Oxygen and hydrogen are most likely to form what type of bond?
tekilochka [14]
Oxygen and Hydrogen would most likely form a covalent bond that is polar, or a polar covalent bond. Due to the electronegativity difference between the 2 elements, unequal sharing of the valence electrons will occur, electrons being in closer proximity to Oxygen and farther away from Hydrogen. Resulting in the characteristic partial positive and negative charges to appear for the respective elements.

The decomposition of ethylene oxide(CH₂)₂O(g) → CH₄(g) + CO(g)is a first order reaction with a half-life of 58.0 min at 652 K. T
olga55 [171]

Answer:

Half-life at 629K = 252.4min

Explanation:

Using Arrhenius equation:

ln\frac{K_1}{K_2}  = \frac{Ea}{R} (\frac{1}{T_2} -\frac{1}{T_1})

And as Half-life in a first order reaction is:

t_{1/2}=\frac{ln2}{K}

We can convert the half-life of 58.0min to know K₁ adn replacing in Arrhenius equation find half-life at 629K:

58.0min=\frac{ln2}{K}

K = 0.01195min⁻¹ = K₁

ln\frac{0.01195min^{-1}}{K_2}  = \frac{218kJ/mol}{8.314x10^{-3}kJ/molK} (\frac{1}{629K} -\frac{1}{652K})

ln\frac{0.01195min^{-1}}{K_2}  =1.47

\frac{0.01195min^{-1}}{K_2}  =4.35

K₂ = 2.75x10⁻³ min⁻¹

And, replacing again in Half-life expression:

t_{1/2}=\frac{ln2}{2.75x10^{-3}min^{-1}}

<h3>Half-life at 629K = 252.4min</h3>
