Acids are flammable true or flase?

False. Acids are not flammable; they do not burn or support combustion.


True or false The particles of a liquid are packed more closely together than the particles of a gas and therefore don't have as much movement?

True. The particles of a liquid are packed more closely together than in a gas, which results in less movement. Liquids have more organized and restricted movement compared to gases, where particles are more spread out and have higher kinetic energy.


True or false a atom is ionized if one of its electrons jumps to a higher energy level in the atom?

Flase ============== Answer #2: Phalse ------------------------------------------------------------------------------------------ Answer number 3 (with no jokes): False. An atom is ionised only when an electron completely leaves the atom.


True or flase particles in liquid move around just freely as particles in a solid?

True. Particles in a liquid have more freedom to move around compared to particles in a solid, which are more tightly packed and have limited movement. In liquids, the particles are able to flow past each other, giving the liquid its characteristic ability to take the shape of its container.


Does the lactase enzyme hydrolyze substrates other than lactose?

Yes it does more than commonly believed. Lactose is just one of the Beta 1to4 "O" glycosides hydrolyzed by the lactase enzyme which is and incorrect nomenclature for the enzyme that is a Beta 1to4 "O" glycosidase. Many who clal them selves experts use the term lactase instead of Beta 1to4 "O" glycosidase due to flase thinking on the matter. Phlorizin, annatto, pectin, tomatine, salicin, various gums and solanine are but a few of those beta 1to4 "O" glycosides that the enzyme Beta 1to4 "O" glycosidase will hydrolyze. E.coli that lives on the proximal and distal sides of the eleocecal valve in humans will ferment, cleave, oxygen and carbon for the reducing end of the glycoside that is part of the aglycones above mentioned.
