It’s water vapor, does this help?
Answer:
B. A rate constant
Explanation:
The mathematical expression of rate law is given below,
Rate = K[A]m[B]n
This rate law show the relationship between the rate of chemical reaction and concentration of reactants.
In given equation [A] and [B] are molar concentration of reactants while K represent rate constant.
The value of K is specific for particular reaction at particular temperature,
m and n are represent exponents and determine experimentally. The value of K is not depend upon the concentrations of reactant but depend upon the surface area and temperature
ANSWER: Eardrum
EXPLANATION:
The vibrations from the eardrum set the ossicles into motion. The ossicles are actually tiny bones — the smallest in the human body. The three bones are named after their shapes: the malleus (hammer), incus (anvil) and stapes (stirrup). The ossicles further amplify the sound.
<u>Answer:</u> The correct answer is Option d.
<u>Explanation:</u>
Nuclear fission reaction is defined as the reaction in which 1 heavier nuclei splits into two or more smaller nuclei.
As, nuclear fission reactors require a large amount of energy to split the nucleus, hence it is bombarded with a particle in order to star the reaction.
In a nuclear reaction, a large fissile atomic nucleus like Uranium-235 or Plutonium-239 when absorbs a neutron, it undergoes nuclear fission reaction.
Hence, in the given options, uranium-235 is absorbing a neutron. Therefore, the correct answer is Option d.
