Answer:
0.500 moles of CO2 has a volume of 11.2 L at STP (option B)
Explanation:
Step 1: Data given
Volume of a gas at STP = 11.2 L
STP: Pressure = 1 atm and temperature = 273 K
Step 2: Calculate volume
p*V= n*R*T
V = (n*R*T)/p
⇒with V = the volume of the gas = TO BE DETERMINED
⇒with n = the number of moles of the gas
⇒with R = the gas constant = 0.08206 L*atm/mol*K
⇒with T = the temperature = 273 K
⇒with p = the pressure of the gas = 1 atm
A
) 0.250 mole of NH3
V = (0.250 * 0.08206 * 273) / 1
V = 5.6 L
B
) 0.500 mole of CO2
V = (0.500 * 0.08206 * 273) / 1
V = 11.2 L
C
) 0.750 mole of NH3
V = (0.750 * 0.08206 * 273) / 1
V = 16.8 L
D) 1.00 mole of CO2
V = (1.00 * 0.08206* 273) / 1
V = 22.4 L
0.500 moles of CO2 has a volume of 11.2 L at STP (option B)
Answer:
i think the answer is helium (top right in periodic table)
Answer:
Explanation:
Melting: it is a phase change from solid to liquid. It is usually attained when a substance reaches it melting point as heat is supplied to it. The vibrating particles break loose and begins to move like a liquid. Melting of iron is an example.
Boiling; is a phase change from liquid to gases. When substances reaches their boiling points when heat is supplied they begin to boil and form gases. An example is the boiling of water. Boiling usually occurs when the vapor pressure is equal to the atmospheric pressure around.
Condensing: is a phase change from gas to liquid. When gases are cooled they condense back to liquid. Example is rain clouds.
Freezing: is a phase change from liquid to solid.
Answer:
diluted or stronger
Explanation:this is caused by the addition of oxygen and it is normally overbearing of ends up changing the whole molecule
The solute of NH3 is water
