parathyroid hormones indirectly activate…
osteoclasts, causing reabsorption of calcium from bones
parathyroid increases Ca by…
inhibiting the kidney’s ability to transfer Ca ions to urine
temperature of a phase change depends on..
intermolecular forces - this is specific heat of capacity (which is also intensive)
compound
any MOLECULE that contains two or more elements. 02 not a compound.
electronegativity is the tendency of an atom…
to attract electrons
double displacement ex.
2 elements just switch places - AB + CD = AD + CB
redox reaction ex (REC the redo)
(redox is just a transfer of electrons) rust formation, combustion, and energy formation in our cells
redox reaction involves a…
transfer of electrons between 2 chemical species - one gains, and one gives up
dissolution means that..(dissolve in water)
the ions that make up a compound are pulled apart and coated with water. It’s literally just dissolving something in water.
delta plus symbol means..(in H20)
that hydrogen atoms are partially cationic, because the shared electron with 0 spends more time near the 0 nucleus. The pull is stronger. This makes it polar.
when an element is reduced, it..
gains an electron
when an element is oxidized, it…(lost ox)
loses an electron
the number of electrons in a redox reaction doesn’t….
change, they just switch places
combustion is a type of____reaction
redox
acid base reaction what type of reaction?___displacement
double displacement
every increase on the pH scale is..
tenfold
used to measure tiny amounts of material
analytical balance
most accurate to use when measuring volume
