Sulfur trioxide, SO3 (g), decomposes into sulfur dioxide gas and oxygen gas according to the following equation: 2SO3 (g) → 2SO2 (g) + O2 (g) Assuming the reaction fully...

2. The inﬂation of an air bag during a car crash is due to production of nitrogen gas, N2(g), by the following reaction: 2NaN3(s) → 2Na(s) + 3N2(g) a) What volume of N2 is...

if a cube is filled with an ideal gas to a pressure of 18.0 atm at 0°C(273K) and volume of the cube doubles and the temperature is raised to 25°C, what is the new pressure?

A container is filled with an ideal gas to a pressure of 15.0 atm at 0°C: If the volume of the container doubles and the temperature is raised by 25°C, what will the new...

I’m very confused on this question: 1.83cm3 of a liquid of density of 0.803gcm-3 was injected into a syringe maintained at 200 celcius. The liquid vaporised completely and occupied 808.54cm3...

I plotted the data points, and I got this for Charles law: y = 1.1906x + 279.18 R² = 0.9619 I don't understand how I'm supposed to get the absolute zero I know that y=mx+c will be V=mT+c...

A 7.50 g sample of lithium metal is dropped into 25.0 mL of 1.5 M hydrochloric acid. What volume of hydrogen gas would be evolved once the limiting reactant has been consumed? (The reaction is performed...

Can you please help me with this problem? Thanks

A fuel composed of (CH3)2N2H2 is mixed with N2O4. The two components react according to the following reaction (CH3)2N2H2+2N2O4=3N2+4H2O+2CO2(all gases). If...

Equal moles of sulfur dioxide gas and oxygen gas are mixed in a flexible reaction vessel and sparked to initiate the formation of sulfur trioxide. Assuming the reaction goes to completion, what is...

Consider two flasks, the first flask has 2.00L of hydrogen at a pressure of 475 torr, the second has 1.00 L of nitrogen at a pressure of 0.200 atm. If the stopcock between the two flasks is opened...

A 1.00 l sample of oxygen has a pressure of 1.0 atm. a 0.50 liter sample of nitrogen gas has a pressure of 1.0 atm.?if these two samples are mixed and compressed in a 1.0 liter vessel, what is the...

I need some help on this last problem, I have been working on this for awhile.
