Answer:
According to avogadro's law, 1 mole of every substance contains avogadro's number of particles and weighs equal to its molecular mass.
To calculate the moles, we use the equation:
a. moles in 14.08 g of =
molecules in 14.08 g of =
b. moles in 17.75 g of NaCl =
molecules in 17.75 g of =
formula units 17.75 g of =
c. moles in 20.06 g of =
formula units in 20.06 g of =
Answer:
Acid: HCl(aq), conjugate base: Cl⁻(aq)
Base: CO₃⁻²(aq), conjugate acid: HCO₃⁻(aq)
The rewrite reaction is shown below.
Explanation:
The acid compound is the one that loses an H⁺, and the compound formed when it happens is its conjugate base. The base compound is the acceptor of H⁺, and its conjugate acid is the compound formed (Brosted-Lowry theory).
So, the acid-base pairs are:
Acid: HCl(aq), conjugate base: Cl⁻(aq)
Base: CO₃⁻²(aq), conjugate acid: HCO₃⁻(aq)
The TUMS® is an antacid, so it intends to reduce the concentration of the strong acid HCl. So, the forward reaction is favored. It can be represented with the forward arrow larger than the reversible arrow, as shown in the image below.
