Answer:
548s = t
Explanation:
A first-order reaction has as general equation:
![ln \frac{[A]_t}{[A]_0} = -kt](https://tex.z-dn.net/?f=ln%20%5Cfrac%7B%5BA%5D_t%7D%7B%5BA%5D_0%7D%20%3D%20-kt)
Where
is the concentration of the reactant in the time t,
is the initial concentration of the reactant, k is rate constant and t is time. Replacing with values of the problem:

-1.65 = -3.00x10⁻³s⁻¹×t
<em>548s = t</em>

Answer:
<h3>The answer is 2.90 L</h3>
Explanation:
In order to find the original pressure , we use the formula for Boyle's law which is

where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the original volume

From the question
P1 = 250020 Pa
P2 = 120870 Pa
V2 = 6 L
We have

We have the final answer as
<h3>2.90 L</h3>

A carbon compound is made up of two parts: R−F, where R is the hydrocarbon part and F is the functional group part.
So, this R (hydrocarbon) part determines the physical properties of a compound and the F (functional group) part determines the chemical properties of the compounds.
