Metals are used in many products because of the characteristic properties that most metals have. The product that requires the high luster of metals is a mirror. Luster is used to describe something that reflect light off a surface. Metals are known to have the quality of reflecting light from its surface therefore it is a good material for the said product.
Let us write succinic acids as H2Suc
The first ionization is
H2Suc ----> HSuc- + H+
The seond ionization is
HSuc- ----> Suc-2 + H+
Calculate the H+ concentration of from the first ionization using pKa1.
Then, calculate the H+ concentration from the second ionization using pKa2.
Next, use the buffer equation to calculate the concentration of the salt in the solution. Then, use the given volume to get the number of moles of the salt. Finally, use the given molecular weight to get the mass.
Answer:
The value of the equilibrium constant (K) remains the same.
Explanation:
A state of dynamic equilibrium is said to have been achieved in a reaction system when the rate of forward reaction equals the rate of reverse reaction.
At equilibrium, doubling the initial concentration of reactants have no effect on the equilibrium constant K. The equilibrium will rather shift to the left or right as required in order to annul the constraint.
Answer:
A
Explanation:
Chemical compound
Lead(II) chloride is an inorganic compound which is a white solid under ambient conditions. It is poorly soluble in water. Lead(II) chloride is one of the most important lead-based reagents. It also occurs naturally in the form of the mineral cotunnite.
Petrified fossils, they are made of wood that becomes petrified from pressure and lack of oxygen.
