1 take it on an empty stomach: then youâll see an effect in 15â30 minutes but itâs risky especially if you do this regularly around the clock.  double the dosage: this is even more risky. Though blood levels will rise faster, you double, maybe even multiply your chances of stomach injury, thatâs 800mg!
Alkali metals are the six elements that comprise Group I in the Periodic Table: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). Especially when dissolved in water, these elements form strong bases (alkalis) capable of reacting with and neutralizing strong acids.
Alkenes. Alkenes are unsaturated hydrocarbons that have one or more carbon-carbon double bond, with a general structure of (R-C=C-R'), where R and R' are hydrocarbon groups attached to either side of the carbon atoms.ydrocarbons are compounds that only consist of the elements hydrogen and carbon. In this lesson, we will focus on one type of hydrocarbon: unsaturated hydrocarbons, and its three types-alkenes, alkynes and aromatic hydrocarbons.
