I think it’s Nanoscale :)) I’m 99% sure it is
Answer:
An atom has a nucleus, made up protons and neutrons, which is surrounded by a cloud of electrons.
Explanation:
An atom is the smallest indivisible part of any element that takes place in a chemical reactions.
These are the fundamental building blocks of every element and even compounds.
- There are three known subatomic particles found within an atom.
- Electrons are the negatively charged particles in an atom
- Protons are the positively charged particles of an atom
- Neutrons do not carry any charges.
Both protons and neutrons are located within the tiny space called nucleus at the center of an atom.
Electrons moves round in orbitals at the spaces outside of the nucleus.
Answer:
a. Rate = k×[A]
b. k = 0.213s⁻¹
Explanation:
a. When you are studying the kinetics of a reaction such as:
A + B → Products.
General rate law must be like:
Rate = k×[A]ᵃ[B]ᵇ
You must make experiments change initial concentrations of A and B trying to find k, a and b parameters.
If you see experiments 1 and 3, concentration of A is doubled and the Rate of the reaction is doubled to. That means a = 1
Rate = k×[A]¹[B]ᵇ
In experiment 1 and to the concentration of B change from 1.50M to 2.50M but rate maintains the same. That is only possible if b = 0. (The kinetics of the reaction is indepent to [B]
Rate = k×[A][B]⁰
<h3>Rate = k×[A]</h3>
b. Replacing with values of experiment 1 (You can do the same with experiment 3 obtaining the same) k is:
Rate = k×[A]
0.320M/s = k×[1.50M]
<h3>k = 0.213s⁻¹</h3>
