Molecule, a group of two or more atoms that form the smallest identifiable unit into which a pure substance can be divided and still retain the composition and chemical properties of that substance.
While Atoms are single neutral particles,
Molecules are neutral particles made of two or more atoms bonded together.
Exaplmes for molecules
H2O (water)
N2 (nitrogen)
O3 (ozone)
CaO (calcium oxide)
C6H12O6 (glucose, a type of sugar)
NaCl (table salt
And examples for atoms
Neon (Ne)
Hydrogen (H)
Argon (Ar)
Iron (Fe)
Calcium (Ca)
Deuterium, an isotope of hydrogen that has one proton and one neutron.
Plutonium (Pu)
F-, a fluorine anion.
Answer:
Carbon, Hydrogen, Oxygen, Nitrogen, and Sulfur.
(Those are all the ones I know)
Answer:
True
Explanation:
Since the waves have low frequency that means the wavelength is going to be longer. Hope this helps
a, c, and d are all chemical properties because they give information about how a substance will behave in the given reaction, and can’t be found without the substance undergoing some sort of chemical reaction. b, on the other hand, is a physical property—it can be determined without changing the substance’s chemical composition.
Answer:
Part A
![rate= 4.82*10^{-3}s^{-1} * [N2O5]](https://tex.z-dn.net/?f=rate%3D%204.82%2A10%5E%7B-3%7Ds%5E%7B-1%7D%20%2A%20%5BN2O5%5D)
Part B
Explanation:
Part A
<em>The rate law is the equation that relates the rate of the reaction, the kinetic constant and the concentration of the reactant or reactants.</em>
For the given chemical reaction we can write a general expression for the rate law as follows:
![rate= k * [N2O5]^{x}](https://tex.z-dn.net/?f=rate%3D%20k%20%2A%20%5BN2O5%5D%5E%7Bx%7D)
where k is the rate constant and x is the order of the reaction with respect of N2O5 concentration. Particularly, <em>a first order reaction kinetics indicate that the rate of the reaction is directly proportional to the concentration of only one reactant</em>. Then x must be 1.
Replacing the value of the rate constant given in the text we can arrive to the following expression for the rate law:
Part B
Replacing the value of the concentration of N2O5 given, we can get the rate of reaction:
