Answer : Option A) the arrangement of bonded atoms.
Explanation : A structural formula of certain molecule depicts the way the atoms are arranged in that particular molecule in any polyatomic species. It helps in deciding the chemical properties of that polyatomic molecule.
The mass of KCl per volume of solution=.35X(35.5+39)=26.075g/L
Answer:
- <u>b. three half-lives</u>
Explanation:
The number of half-lives elapsed, n, is calculated dividing the time by the half-life time:
- n = time / half-life time
<u>a. A sample of Ce-141 with a half-life of 32.5 days after 32.5 days</u>
- n = 32.5 days / 32.5 days = 1 half-life
<u />
<u>b. A sample of F-18 with a half-life of 110 min after 330 min</u>
- n = 330 min / 110 min = 3 half-lives
<u />
<u>c. A sample of Au-198 with a half-life of 2.7 days after 5.4 days</u>
- n = 5.4 days / 2.7 days = 2 half-lives
Answer:
A supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.

Answer:
<h3>The answer is 223.0 cm³</h3>
Explanation:
To find the volume when the pressure is at 202.6 kPa we use 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 final volume
From the question
P1 = 99.3 kPa = 99300 Pa
V1 = 455 cm³
P2 = 202.6 kPa = 202600
So we have
We have the final answer as
<h3>223.0 cm³</h3>
