Barium chloride + sodium sulphate --> barium sulphate + sodium chloride
BaCl2 + Na2SO4 ---> BaSO4 + 2 NaCl
The barium sulphate appears as a white precipitate
Silver nitrate + Sodium chloride ---> Silver Chloride + sodium nitrate
AgNO3 + NaCl ----> AgCl + NaNO3
The silver chloride appears as a white precipitate.
These are sometimes called double decomposition reactions.
The phrase that describes a characteristic of an Arrhenius base is that Arrhenius base add hydroxide ions to the solution ( answer C)
<u><em>Explanation</em></u>
Arrhenius base is a substance that increases the concentration of OH- in aqueous solution.
The Common Arrhenius base are group 1 and 2 hydroxide such as LiOH, NaOH , Ba(OH)2 among others.
for example NaOH dissociate as follows , NaOH → Na+(aq) + OH- (aq)
The correct equation
for the overall reaction can simply be obtained by adding the two separate
equations together. Now when you add the two equations together, the overall K can
be calculated by multiplying the individual K values. Therefore:<span>
K(overall) = K1 * K2 </span>
K(overall) = (1.6 x
10^-10) * (1.5 x 10^7)
<span>K(overall) = 2.4 x
10^-3</span>
Protons, nuetrons, and electrons
Amino Acids undergo a kind of acid base reaction within a molecule. The
Amino group acts as a base and accepts proton from
Carboxylic functional group resulting in formation of
Ammonium with positive charge and a negative charge on
Carboxylate. Such molecules containing both positive and negative charges are called as
Zwittor Ions.
Phenylalanine both in Un-ionized and Ionized form is shown below,
