A lithium atom starts from rest at a position x = xo and falls toward zinc atom with an acceleration that depends on their separ

ation as a(x) = 4Eϵ/m { 12 (σ^12/σ^13) -6 (σ^6/σ^7) where ϵ, m, and σ are positive constants, and the zinc atom stays fixed at position x = 0, Assume that xo > 2^(1/6)σ. a. Find an expression for how the velocity of the moving lithium atom depends on x. (It will also depend on ϵ, m, xo and σ) b. What is the distance of closest approach of the the two atoms (in terms of σ and xo)?

The smell of hot food moves faster than the smell of cold food. Which property of gas is responsible for this?
miskamm [114]
When pressure is added to a gas the molecules bounce around really fast and push against the walls of its container. That's why when you squeeze an empty water bottle you can crush it all the way. The smaller the container the more the molecules hit the walls faster and that's what creates pressure. While moving around the molecules get hot as they speed up. Heat = Pressure.

Matter has mass and takes up ______________. The amount of space that matter
svlad2 [7]
Answer:
space

Explanation:
Matter possesses mass and occupies space around it. The space is measured using the property known as volume. Different states of matter occupy spaces in different ways depending on how big, small, rigid, flowing etc. they are. Hence, each state of matter appears a bit differently and they have different volume.

Which solution contains the smallest number of moles of sucrose (c12h22o11, molar mass = 342.30 g/mol)? 2,000 ml of a 5.0 × 10–5
Iteru [2.4K]

> 2,000 mL of a 5.0 × 10–5% (w/v) sucrose solution 

5.0 × 10–3 g/mL * 2000 mL * (1 mol / 342.30 g) = 0.0292 mol

<span>
> 2,000 mL of a 5.0 ppm sucrose solution</span>

5 grams / 1000000 mL * 2000 mL* (1 mol / 342.30 g) = 0.0000292 mol

 <span>
> 20 mL of a 5.0 M sucrose solution </span>

5.0 M * 0.020 L = 0.1 mol

 

 

Answer:

the volume of gas in a container was originally 3.24L, while at standard pressure 1.00 atm. what will the volume be if the press
Simora [160]
Hello!

To solve this problem, we will use the Boyle's Law, which describes how pressure changes when volume changes and vice-versa. The equation for this law is the following one, and we'll clear for V2:

P1*V1=P2*V2 \\ \\ V2= \frac{P1*V1}{P2}= \frac{3,24 L * 1 atm}{1,20 atm}= 2,7 L

So, the final volume after increasing the pressure would be 2,7 L. That means that volume decreases when the pressure increases
