Answer:
6^3 I believe.
Explanation:
If it's wrong it may be 6^2 because you should square it, but I think it's 6^3
Answer: E. It decreases the value of Eact.
Explanation:
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and more molecules convert to products.
The catalyst itself does not take part in the chemical reaction and is regenerated as such at the end.
Answer:
1-bromo-6-chloro-5-methylheptane
Explanation:
There are 3 substituents, 1 chlorine, 1 bromine, and 1 methyl group.
The longest carbon chain consists of 7 carbons.
There are no double bonds, based on the saturation and substituents.
So you have a 1-bromo-6-chloro-5-methylheptane.
Hope that was the brainliest answer!
Answer:
Explanation:
We must use the Nernst equation
Step 1. Calculate E°
SO₄²⁻(aq) + 4H⁺(aq) + 2e⁻ ⇌ SO₂(g) + 2H₂O(ℓ)
<u>2Br⁻⇌ Br₂(aq) + 2e⁻ </u>
SO₄²⁻(aq) + 4H⁺(aq) + 2Br⁻(aq) ⇌ Br₂(aq) + SO₂(g) + 2H₂O(ℓ)
E° = 0.17 - 1.0873 = -0.92 V
Step 2. Calculate Q
E = 0 V
E° = -0.92 V
R = 8.314 J·K⁻¹mol⁻¹
T = 66 °C
n = 2
F = 96 485 C/mol
Calculations:
T = 66.0 + 273.15 = 339.15 K
Answer:
The waitress thought the man meant H202 which is Hydrogen Peroxide. The man drank the Hydrogen Peroxide and then died.
