Answer: Explanation:
You can change an object's state of matter by adding or removing thermal energy. When you add thermal energy to an object, these things can happen: Particles move faster (increased kinetic energy). Particles get farther apart (increased potential energy).

Answer:
9302 moles of CO contain 5.60×10²⁷ molecules
Explanation:
We solve this with Avogadro's number.
NA = 6.02×10²³
This number states the how many particles are in 1 mol of anything.
1 mol of atoms contains 6.02×10²³ atoms
1 mol of molecules contains 6.02×10²³ molecules.
We apply a rule of three:
6.02×10²³ molecules are contained in 1 mol of CO
Then, 5.60×10²⁷ molecules may be contained in (5.60×10²⁷ . 1) / 6.02×10²³
= 9302 moles
Answer:
3.762 atm.
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 n and T are constant, and have different values of P and V:
<em>(P₁V₁) = (P₂V₂)</em>
<em></em>
P₁ = 894.0 torr, V₁ = 534.0 mL,
P₂ = ??? torr, V₂ = 167.0 mL.
- Applying in the above equation
(P₁V₁) = (P₂V₂)
<em>∴ P₂ = (P₁V₁)/V₂</em> = (894.0 torr)(534.0 mL)/(167.0 mL) = <em>2859 torr.</em>
- To convert from torr to atm:
1.0 atm = 760.0 torr.
<em>∴ P₂ </em>= (2859 torr)(1.0 atm/760 torr) = <em>3.762 atm.</em>
