Answer:
0.212
Explanation:
(5.30g) / (5.30g + 19.7g)
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:
Most likely phosphorus, antimony, arsenic, boron, indium or gallium. The wiring is composed mainly of copper, gold, and silver.
Answer:
Explanation:
At STP, 1 mole of hydrogen can occupy a volume of 22.4 liters. At STP, 3 moles of hydrogen can occupy a volume of 2×22. 4=44. 8 liters
