How much heat is associated with the burning of 2.14 g of methane in the following unbalanced reaction: CH4(g) + O2(g) →CO2(g) + H2O(g)?
A 1-L flask is filled with 1.10 g of argon at 25 C. A sample of ethane vapor is added to the same flask until the total pressure is 1.20 atm . What is the partial pressure of argon,PAr , in the flask?
The compound [Fe(CO)4(PMe3) could adopt a trigonal bipyramidal geometry with the phosphine in either an axial or an equatorial position. (a) Indicate the point group of the molecule
You prepare a suspension by dispersing 20.0 g solid compound with the aqueous dispersant (outer phase of the suspension) to a final volume of 100.0 ml. The dispersant contains 10% w/v glycerol and 0.5% w/v polysorbate 80. The density of the solid ..
The equilibrium constant, Kp , for the reaction CO(g) + H2O(g)-> CO2(g) + H2(g) at 986°C is 0.63. A rigid cylinder at that temperature contains 1.2 atm of carbon monoxide, 0.20 atm of water vapor
My gas tank in my car has a total volume of 68 L. The manual says the gas gauge light will come on when there are only 5 L remaining in the tank and that the car will not be able to draw on the last 2 L in the tank.
