produced heat and bubbles‚ both indications of a chemical change. A wood splint was used to determine that the gas produced was hydrogen gas‚ hence the other product is magnesium dichloride. In the third reaction‚ ammonium carbonate was heated to decompose into two gases‚ due to the absence of anything solid or liquid following the reaction. A wood splint was used to determine that carbon dioxide was present‚ since the lit splint was extinguished when put in the test tube. Therefore‚ the other product

Unit 1 Problem Set 1 26. Surgery Versus Splints A study compared surgery and splinting for subjects suffering from carpal tunnel syndrome. It was found that among 73 patients treated with surgery‚ there was a 92% success rate. Among 83 patients treated with splints‚ there was a 72% success rate. Calculations using those results showed that if there really is no difference in success rates between surgery and splints‚ then there is about 1 chance in 1000 of getting success rates like the ones obtained

Wilford Hall Medical Center. At my previous assignment at Sheppard Air Force Base‚ I worked in a clinic. There if we had a new patient that came in with a splint‚ we would remove the splint and send the patient to get an x-ray before seeing the provider.

The thermal decomposition of nitrates – ‘writing with fire’ 31 A message is written on filter paper with a solution of sodium nitrate and is then dried‚ rendering it invisible. Applying a glowing splint to the start of the message makes the treated paper smoulder and the message is revealed as the glow spreads its way through the treated paper.
