What is the molarity of a solution prepared by dissolving 8 grams of BaCl2 in enough
olga55 [171]

Answer:

Explanation:

molar mass of BaCl2 = 208.23

mol of BaCl2 = 8/208.22

mol of BaCl2 = 0.03841905

Molarity = 0.03841905/0.450

Molarity = 0.085 M

Write a net ionic equation to show how quinoline, c9h7n, behaves as a base in water.
Natalija [7]

Quinoline, C_{9}H_{7}Nacts a Bronsted-Lowry base as it can accept a proton, H^{+}from water to form the conjugate base, C_{9}H_{7}NH^{+}. This reaction can be represented as,

C_{9}H_{7}N(aq)+H_{2}O(l) C_{9}H_{7}NH^{+}(aq)+OH^{-}(aq)

Here in the reaction, the weak base quinoline accepts a proton H^{+}from water to form the conjugate base of quinoline, C_{9}H_{7}NH^{+} and hydroxide ion, OH^{-}

Therefore the net ionic equation to show the basic nature of quinoline in water is,

C_{9}H_{7}N(aq)+H_{2}O(l) C_{9}H_{7}NH^{+}(aq)+OH^{-}(aq)
