Answer:
The answer is D.8 sulfer atoms and 16 oxygen atoms
Explanation:
Answer:
59.077 kJ/mol.
Explanation:
- From Arrhenius law: <em>K = Ae(-Ea/RT)</em>
where, K is the rate constant of the reaction.
A is the Arrhenius factor.
Ea is the activation energy.
R is the general gas constant.
T is the temperature.
- At different temperatures:
<em>ln(k₂/k₁) = Ea/R [(T₂-T₁)/(T₁T₂)]</em>
k₂ = 3k₁ , Ea = ??? J/mol, R = 8.314 J/mol.K, T₁ = 294.0 K, T₂ = 308.0 K.
ln(3k₁/k₁) = (Ea / 8.314 J/mol.K) [(308.0 K - 294.0 K) / (294.0 K x 308.0 K)]
∴ ln(3) = 1.859 x 10⁻⁵ Ea
∴ Ea = ln(3) / (1.859 x 10⁻⁵) = 59.077 kJ/mol.
Answer: The correct is 0.5 moles.
Explanation:
Answer:
The waxy substance is warm.
The waxy substance is less dense than the surrounding liquid.
Convection is occurring.
Explanation:
Convection involves heat transfer by the actual movement of the particles of a substance.
When the wax is heated, the waxy substance becomes warm and rises in the lamp. The warm waxy substance is less dense than the surrounding liquid, this process of rising and falling is as a result of convection occurring in the lava lamp.
Butane and isobutane are structural isomers. Isobutane is produced by the isomerization reaction of butane.
CH3CH2CH2CH3--(t°,AlCl3)-›CH3CH(CH3)-CH3.
They have the same chemical formula C4H10.But structural formulas are different
Butane CH3CH2CH2CH3
Isobutane CH3CH(CH3)CH3
Isobutane has methyl radical.
