Air molecules are spaced far apart is the answer. Since air is a gas, it’s safe to say its particles are separated in random ranges and fits the statement well.
Answer:
Explanation:
Here, we want to get the new volume of the gas
What we need to know is the law that connects volume and pressure at constant temperature
The law that supports this is the Boyle's law
It states that the volume of a given mass of gas is inversely proportional to its pressure at constant temperature
Mathematically, we can have this as represented as:
We can proceed mathematically to solve as follows;
The required volume of 0.10M NaOH solution that student will add is 20 mL.
<h3>How do we calculate the volume?</h3>
Volume of any solution which is required to prepare buffer will be calculated by using the below equation as:
M₁V₁ = M₂V₂, where
- M₁ & V₁ are the molarity and volume of NaOH solution.
- M₂ & V₂ are the molarity and volume of HF solution.
On putting values, we get
V₁ = (0.1)(20) / (0.1) = 20mL
Hence required volume of NaOH solution is 20mL.

Answer:
2–
Explanation:
Oxygen is in the 6th group originally has a charge of 1–, but when oxygen gets two electrons added to make it a stable gas configuration of s2 p6 it changes it to 2– to form an oxide ion
