CloudLabs Aldehyde Synthesis
Read full descriptionHide full description
In this practice it is possible to carry out the synthesis of acetaldehyde (ethanal), used as a precursor in the polymerization of plastics, from ethanol and a sulfochromic mixture (chromic acid and sulfuric acid). The simulator recreates a chemistry laboratory with a three-mouth balloon, a Vigreux column, a condenser, Erlenmeyer, pipettes, a crystallizer, a Tollens test, a Fehling test, and a Schiff test, among other instruments and supplies necessary to perform the synthesis.

Introducing and explaining the mysterious phenomenon derived from the theory of relativity. In particular, we will detail the changes in the way time progresses. The interstellar flight screen shows how time progresses in response to rocket speed. Shows the difference in how time progresses between rockets and the earth in space travel. The GPS screen shows that gravity changes the way time progresses.

Verdict
The clearest difference is price: CloudLabs Aldehyde Synthesis at Free against RelativityTheory's $0.99. CloudLabs Aldehyde Synthesis also leads on iOS requirement (9.0 vs 14.4). RelativityTheory's advantage is update cadence (every 3 weeks vs every 29 months). On ads, in-app purchases and device support there is nothing between them.
