The hydrolysis of sucrose (c12h22o11) into glucose and fructose in acidic water has a rate constant 1. 8 x 10–4 s–1 at 25oc. Assuming the reaction is first order in sucrose, determine the mass, in grams, of sucrose that is hydrolyzed when 2. 55 l of 0. 150 m sucrose solution is allowed to react for 195 minutes.

Match the scsi standard to the definition that best describes it. 1. also called ultra scsi; has a transfer rate up to 30 mbps and 8-bit bus 2. transfer rate of 5 mbps and 8-bit bus 3. also called firewire; has a transfer rate up to 100 mbps and can connect up to 63 devices 4. consists of two protocols; fast scsi with speeds up to 10 mbps using an 8-bit bus and wide scsi, which uses 16- or 32-bit buses serial scsi scsi-2 scsi-3 scsi-1
