- Question #e395e - Socratic
When decaying by alpha emission a nucleus drops by 4 in mass number and 2 in atomic number and emits a helium nucleus (alpha particle) which has mass number 4 and atomic number 2 194 81 T l → 190 79 Au + 4 2α Notice that the total mass number, and total charge (here only indicated by the atomic numbers ) remains unchanged, just moved around If the question meant another isotope, just
- What is the mass of 211mL of a liquid that has a density of . . . - Socratic
Approx 190*g By definition, rho, is given by the quotient rho_"density"="mass" "volume", and thus has units of g*mL^-1-=g*cm^-3 And so we simply rearrange
- Question #a225d - Socratic
WARNING! Very long answer! > The Ester Value is the number of milligrams of potassium hydroxide required to react with the esters in 1 g of a fat or oil Triglycerides (fats and oils) are important raw materials in the preparation of soaps Three measures of quality are the Acid Value, the Saponification Value, and the Ester Value "Ester Value = Saponification Value - Acid Value" Acid Value
