Z is the lowest frequency wave
Answer:
- Option d. i<u><em>t is higher than the energy of both reactants and products</em></u>
Explanation:
<em>Activated complex</em>, also known as transition state, is the intermediate structure formed in the course of a chemical reaction.
The activated complex is very unstable and of short life: it is at the peak of the potential chemical diagram, and can transform either into the reactants (backward) or the products (forward).
The activation energy of the reaction is the energy needed to reach the activated complex, then both reactants and products are lower in potential chemical energy than the activated complex, which is what explains why the activated complex can transform into one or another, reactants or products.
Answer:
Explanation:
Carbon Dioxide-CO2
To get molecules, we must convert grams to moles and moles to atoms using Avogadro's number.
Molar mass of CO2=
C:12.0g+O:16.0gx2=44.0g CO2
25.0g CO2 | 1 mol CO2 | 6.02x10 23 molecules CO2
= 3.42x10 23 molecules CO2
1 | 44.0g CO2 | 1 mol CO2
Now to get the number of oxygen atoms.
Since there are 3 atoms in CO2 and 2 of them are oxygen, we will divide by 3 (1.14x10 23) and multiply by 2 (2.28 x10 23)
So the number of oxygen atoms in 25.0 grams of CO2 is 2.28x10 23 or 228 000 000 000 000 000 000 000
