one mole of He gan changes its state from (10 atm, 100 k) to ( 1 atm, 1000 k). then change in entropy (delta s) will be 2.303 x cal. what is x. (take R = 2cal/mol)

Drag the tiles to the correct locations. each tile can be used more than once, but not all tiles will be used. one or more locations will remain empty. nitrosyl fluoride has the chemical formula nof nitrogen has five valence electrons, oxygen has six, and fluorine has seven. complete the lewis structure for this covalent compound. f n = = = . : : 0 : reset next um. all rights reserved us 2

Butane gas reacts with oxygen gas to give carbon dioxide gas and water vapor (gas). if you mix butane and oxygen in the correct stoichiometric ratio, and if the total pressure of the mixture is 390 mmhg, what is the pressure (in mmhg) of water vapor after the reaction is completed (temperature and volume do not change).
