Answer:
the correct answer:
C, B, D, A.
Explanation:
The chemical compounds named are compounds that have strong chemical bonds, forming cubic structures and crystals with very high boiling and melting points to less solid structures.
some are oxides, others salts, others are even used to emit radiation.
In a neutral atom the total positive charge cancels out the total negative charge
For this to happen the number of protons(+) and electrons(-) must be the same.
So a neutral atom of Palladium will also have 46 protons (same as the electron no.)
After sixth half life, there will be 3.13% of the initial N₂O concentration.
<h3>What is half life?</h3>
The amount of time it takes for the N₂O concentration to drop to half its starting value is known as the reaction's half life.
We start out with all of the N₂O (100% N₂O). 50% of N₂O will be present after the first half of life, and 25% will be present after the second half of life and so on.
This suggests that after the sixth half life, we will still have 3.13% of the initial N₂O concentration.
So, it takes 6 half lives to get 3.13% of the concentration.
I understand the question you are looking for is this:
Nitrous oxide (N₂O) is used as an anesthetic (laughing gas) and in aerosol cans to produce whipped cream. It is also a potent greenhouse gas. The decomposition of N₂O is first order. It decomposes slowly to N₂ and O₂:
2N₂O(g) --> 2N₂(g) + O₂(g)
How many half-lives will it take for the concentration of the N₂O to reach 3.13% of its original concentration?

Answer : The ratio of the volume divided by the temperature for the first data pair is, ![2.6\times 10^{-3}](https://tex.z-dn.net/?f=2.6%5Ctimes%2010%5E%7B-3%7D)
Explanation :
As we are given the temperature (276 K) and volume
. Now we have to calculate the ratio of the volume divided by the temperature for the first data pair.
![\frac{V}{T}=\frac{0.72}{276}=2.6\times 10^{-3}](https://tex.z-dn.net/?f=%5Cfrac%7BV%7D%7BT%7D%3D%5Cfrac%7B0.72%7D%7B276%7D%3D2.6%5Ctimes%2010%5E%7B-3%7D)
The significant rule for division is the least number of significant figures used in the operation.
As, there are 2 significant figures in numerator and 3 significant figures in denominator. So, the answer will be in least number of significant figure that is, 2 significant figure.
Hence, the ratio of the volume divided by the temperature for the first data pair is, ![2.6\times 10^{-3}](https://tex.z-dn.net/?f=2.6%5Ctimes%2010%5E%7B-3%7D)
Answer:
The arrangement of particles is least ordered is a > c > b > d
Explanation:
Given that,
The arrangement of particles is least ordered in a sample of NaCl.
We know that,
The least ordered arrangement are.
The form of state of particle in least ordered.
So, The least ordered arrangement will be
aqua > gas > liquid > solid
The arrangement of particles is least ordered in a sample of NaCl
![NaCl(aq) > NaCl(g) > NaCl(l) > NaCl(s)](https://tex.z-dn.net/?f=NaCl%28aq%29%20%3E%20NaCl%28g%29%20%3E%20NaCl%28l%29%20%3E%20NaCl%28s%29)
Hence, The arrangement of particles is least ordered is a > c > b > d
