the answer is 0.000097 KM
Answer:
D
Explanation:
The formula for calculating kinetic energy is 1/2mv^2, where m is the mass and v is the velocity or speed of the object. Since all of the balls have the same mass, the one with the highest speed or velocity will have the highest kinetic energy. Hope this helps!
Sublimation takes place when an element or compound changes directly from a solid into a gas without passing through the liquid state....

Answer:
6.5 liters.
Explanation:
- We can use the general law of ideal gas: PV = nRT.
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If P and T are constant, and have different values of n and V:
<em>(V₁n₂) = (V₂n₁)</em>
<em></em>
V₁ = 4.5 L, n₁ = 0.80 mol,
V₂ = ??? L, n₂ = 0.35 + 0.80 = 1.15 mol.
- Applying in the above equation
<em>(V₁n₂) = (V₂n₁)</em>
<em></em>
<em>∴ V₂ = (V₁n₂)/n₁ </em>= (4.5 L)(1.15 mol)/(0.8 mol) = <em>6.469 L ≅ 6.5 L.</em>
<em></em>
<em>So, the right choice is: 6.5 liters.</em>
