Option B.
C (activation energy) would decrease meaning that the catalyst provides an alternative path where lower activation energy is needed for a reaction to take place.

Answer: The current model of the atom shows an atom that is mostly empty space. In the center is a small nucleus made of protons and neutrons. The nucleus contains nearly all the mass of an atom. This model continues to be refined as new technology is developed that allows us to better observe atoms and their behavior.
<h3><u>Answer;</u></h3>
HCl dissociates more.
<h3><u>Explanation</u>;</h3>
- HCl is a strong acid while HC2H3O2 is a weak acid. A strong acid such as HCl ionizes or dissociates completely in an aqueous solution by losing one proton.
- A weak acid is one that does not dissociate completely in solution; this means that a weak acid does not donate all of its hydrogen ions (H+) in a solution. For example; HC2H3O2.
Answer:
7.8 × 10∧-4 nm³
Explanation:
Given data:
volume = 7.8x10^-31 m^3
volume in nm³= ?
Solution:
I m³ = 1 × 10∧27
7.8 x 10^-31 × 1 × 10∧27 = 7.8 × 10∧-4 nm³
