60 elements! I don't exactly know every element known, so if you are asking that, please tell us, but what I do know is that there were 60 elements in the periodic table by 1860.
Predict the effect of each of the following on the indicated equilibrium system in terms of which reaction will be favored
H2(g)+Cl2(g)<=>2HCl(g) +184 kJ addition of Cl2 removal of HCl increased pressure decreased temperature removal of H2 decreased pressure addition of a catalyst increased temperature decreased system volume
im sorry i am not sure if this is the answer you are looking for
Answer:
pH = 2
A 0.010 M solution of hydrochloric acid, HCl, has a molarity of 0.010 M. This means that [H+] = 1 x 10-2 M. The pH of this aqueous solution of H+ ions is pH = 2
hope this helps :3
Answer:
.00352mol/L
Explanation:
molarity (concentration) = number of moles / volume of solvent (in L)
M = .99g / 56.108g/mol / .5L
M = .0176mol / .5L
M = .00352mol/L
Answer:
The position of an equilibrium always shifts in such a direction as to relieve a stress applied to the system. - <u>Le Chatelier's principle</u>
A molecule that donates a proton when it encounters a proton acceptor. - <u>Bronsted-Lowry acid</u>
Occurs when a reaction involving an acid and its conjugate base is combined with a second reaction involving a base and its conjugate acid. - <u>Neutralization</u>
It ionizes completely when dissolved in water. - <u>Strong acid</u>
The shift in the position of equilibrium caused by the addition of a participating ion. - <u>Common ion effect</u>
It only partially ionizes when dissolved in water. - <u>Weak electrolyte</u>
It is capable of acting as either an acid or a base depending upon the solute. - <u>Amphoteric solvent</u>
The act of self-ionization of a solvent to produce both a conjugate acid and a conjugate base. - <u>autoprotolysis </u>
A chemical species that bears both positive and negative charges. - <u>zwitter ion</u>
