Atomic number: 26
atomic mass: 56
this is all i know sorry :(
4NH2(g)+5O2(g) ---->()4NO(g)+6H2O(g)
In chemical changes new substances are formed and the process is often difficult to reverse. During chemical changes particles do change with atoms or ions regrouping. Bonds between atoms break and new ones form and energy is either given out or taken in. Some chemical changes are initiated by mixing
Answer:
lets set the ratio -A/HA as R:
pH = pKa + log(R,10) => pKa + log10(R)
pH = 5.5
pKa = 4.76
R => 10^(pH - 4.76)
10^(pH - 4.76) => 5.4954
Given R (-A/HA) a number bigger than 1, then the concentration of -A is bigger than HA
