Answer: 96.34%
Explanation:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = time for decomposition = 300 years
a = let initial amount of the reactant = 100
a - x = amount left after decay process = ?
Thus 96.34 percent of a given amount remains after 300 years.
Answer:
newton's 3 laws state:
- an object in motion stays in motion (unless an external force acts on it)
- every action has an opposite but equal reaction
- force= mass x acceleration
Answer:
Toasting Bread
Explanation:
Toasting bread cannot be transformed
Answer:
The names of the electron shell were given by a spectroscopist named Charles G Barkla. He named the innermost shell has k shell because he noticed that the X-rays emitted two types energies. These energies were named as type A that is higher energy X-ray and type B that is lower energy X-ray. Later these energiers were named with different alphabets. He noticed that K type X-rays emitted the highest energy. Therefore, he named the innermost shell as the K shell.
