Asolution of hno, is standardized by reaction with pure sodium carbonate 2h*+na, co,2 nat +h0+co a volume of 24.76 t 0.05 ml of hno, solution was required for complete reaction with 0.9452 + 0.0007 g of na, co, (fm 105.988 0.001 g/mol). find the molarity of the hno, solution and its absolute uncertainty. note: significant figures are graded for this problem. to avoid rounding errors, do not round your answers until the very end of your calculations m t 0.002 m hno,]= 0.7372

Describe the particles of all three phases of matter in the root beer float. (how are the particles arranged and moving? )

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.

Which of the following is a conclusion that resulted from ernest rutherford’s scattering experiment? (will mark brainliest) a. the nucleus is negatively charged b. the atom is a dense solid and is indivisible c. the mass is conserved when atoms react chemically d. the nucleus is very small and the atom is mostly empty space
