-273.15 o c, 0 o c is equal to 273.15 kelvins. the kelvin scale is used for very low or very high temperatures when water is not involved. the kelvin scale of heat measurement differs from the centigrade and fahrenheit scales in that it starts from absolute zero, the lowest possible ...
Question: Ammonia acts as a base in aqueous solution; Kb is equal to {eq}1.8 \times 10^{-5} {/eq}. What is the Ka for the ammonium ion {eq}NH_4^+ {/eq} in aqueous solution? Acid-Base Equilibrium When the solution ...
Science Chemistry Acid dissociation constant Given that Ka for HCN is 6.2 x 10^-10 at 25 C, what is the value of Kb for CN- at 25 C?Question: Given that Ka for HCN is 6.2x10−10 at 25 degrees Celsius, what is the value of Kb for CN− at...
an atom’s valence is equal to the number of electrons in the outer shell when that number is four or fewer. then the valence in the outer shell is equal to eight minus the number of electrons. once you are aware of the number of electrons you can calculate the valence easily. test ...
(geometry) Equal in measure but not admitting of superposition; applied to magnitudes. A square may be equivalent to a triangle. Equivalent Anything that is virtually equal to something else, or has the same value, force, etc. Equivalent (chemistry) An equivalent weight. Equivalent (transitive)...

Note: Atomic mass is a dimensionless quantity. Since the atomic number of sodium is 11, it has got 1 electron in the valence shell. Therefore, the valency of sodium is 1. The number of protons is equal to the number of electrons in sodium. But when s...
Ceteris paribus is a Latin phrase that generally means "all other things being equal." In economics, it acts as a shorthand indication of the effect one economic variable has on another, provided all other variables remain the same. Many economists rely on ceteris paribus to describe relative ...
