Answer:
The pressure, when the volume is reduced to 7.88L, is 846 torr (option A)
Explanation:
Step 1: Data given
The temperature of a gas = 25.0°C
AT 25 °C the gas occupies a volume of 10.0L and a pressure of 667 torr.
The volume reduces to 7.88 L but the temperature stays constant.
Step 2: Boyle's law
(P1*V1)/T1 = (P2*V2)/T2
⇒ Since the temperature stays constant, we can simplify to:
P1*V1 = P2*V2
⇒ with P1 = the initial pressure 667 torr
⇒ with V1 = the initial volume = 10.0 L
⇒ with P2 = the final pressure = TO BE DETERMINED
⇒ with V2 = the final volume = 7.88L
P2 = (P1*V1)/V2
P2 = (667*10.0)/7.88
P2 = 846 torr
The pressure, when the volume is reduced to 7.88L, is 846 torr (option A)
Answer:
2.956 moles chlorine gas will be produced
Explanation:
Step 1: data given
Number of moles carbon tetrachloride (CCl4) = 0.739 moles
carbon disulfide (s) = CS2(s)
chlorine (g) = Cl2(g)
carbon tetrachloride (l) = CCl4(l)
sulfur dichloride (s) = SCl2 (s)
Step 2: The balanced equation
CS2(s) + 4Cl2(g) → CCl4(l) +2SCl2
Step 3: Calculate moles chlorine gas
For 1 moles Cs2 we need 4 moles Cl2 to produce 1 mol CCl4 and 2 moles SCl2
For 0.739 moles CCl4 we need 4*0.739 = 2.956 moles Cl2
2.956 moles of chlorine gas will be produced
Answer:
This effect is caused by increased levels of carbon dioxide, chlorofluorocarbons and other gases in the air, many of them released by human activity. greenhouse effect The warming of Earth's atmosphere due to the buildup of heat-trapping gases, such as carbon dioxide and methane.
