A 21.5-liter gas cylinder contains 7.7 moles of nitrogen gas and 3.4 moles of oxygen gas. If the temperature of inside the cylinder is 0 °C, what is the total pressure inside the cylinder? Potal == atm

Oxalic acid,  H2C2O4,  a poisonous colorless solid, is found in some vegetables such as spinach and rhubarb. It is present in concentrations well below the toxic limit, so you can't use this as a reason to refuse a helping of spinach. The order of atoms in a molecule of oxalic acid is  HO2CCO2H.  (a) How many unshared pairs of electrons are on each of the carbon atoms?   (b) How many unshared pairs of electrons are on each of the oxygen atoms?

A gas cannister, in which the pressure is initially 1.50 atm at 31°C, is heated until the internal pressure is 3.60 atm. What will be the new temperature, in °C, inside the cannister? (Note: First, convert the temperature to Kelvin.) Do not include temperature units in this answer. °C

what is the temperature in (in Celcius ) did an ideal gas shift to if it was initially at -14.0 c at 4.62 atm and 35.0L and the pressure was changed to 8.71 atm and the volume changes to 15.0L?
