Answer:
Cobalt lose 3 electrons and donate 12 electrons.
Explanation:
In the periodic table,cobalt has nine electrons .It has lost 3 electrons,so it is only six left.Once it forms the complex,each ammonia donates a pair of electrons.
Answer:
D
Explanation:
Molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly.
Answer:
The activation energy is 7.11 × 10⁴ J/mol.
Explanation:
Let's consider the Arrhenius equation.
where,
k is the rate constant
A is a collision factor
Ea is the activation energy
R is the ideal gas constant
T is the absolute temperature
The plot of ln k vs 1/T is a straight line with lnA as intercept and -Ea/R as slope. Then,
