Answer:
The wave produced by a fireworks "explosion" is a light wave.
Explanation:
Answer : The value of activation energy for this reaction is 108.318 kJ/mol
Explanation :
The Arrhenius equation is written as:
Taking logarithm on both the sides, we get:
............(1)
where,
k = rate constant =
Ea = activation energy = ?
T = temperature = 435 K
R = gas constant = 8.314 J/K.mole
A = pre-exponential factor =
Now we have to calculate the value of rate constant by putting the given values in equation 1, we get:
Therefore, the value of activation energy for this reaction is 108.318 kJ/mol
No one is 100% sure when particles of matter originated however scientist believe it had to be some time before the Big Bang
Answer:
Avogadro's number is 6.022×1023 molecules. With Avogadro's number, scientists can discuss and compare very large numbers, which is useful because substances in everyday quantities contain very large numbers of atoms and molecules.
