Identify the limiting and excess reactants when 1.00 g of zinc reacts with 150 ml of 0.250m pb(no3)2. how many grams of lead are formed in this single replacement reaction

The reaction equation is:
Zn + Pb(NO₃)₂ → Pb + Zn(NO₃)₂

The moles of lead are calculated using:
moles = concentration x volume
moles = 0.25 x 0.15
moles = 0.0375

The moles of zinc are: 1 / 65 = 0.015

We see from the equation that equimolar quantities of zinc and lead should be present. Therefore, lead is in excess and zinc is the limiting reactant.

The pair that consists of a base and its conjugate acid in that order.

Explanation:

According to the Bronsted-Lowry conjugate acid-base theory, an acid is defined as a substance which looses donates protons and thus forming conjugate base and a base is defined as a substance which accepts protons and thus forming conjugate acid.

 is gaining a proton, thus it is considered as a brønsted-lowry base and after gaining a proton, it forms  which is a conjugate acid.
