1. If a solution of sodium chloride has 22.3 g of

lina2011 [118]

We are given:

Mass of NaCl in the given solution = 22.3 grams

Volume of the given solution = 2 L

Number of Moles of NaCl:

We know that the number of moles = Given mass / Molar mass

Number of moles = 22.3 / 58.44 = 0.382 moles

Molarity of NaCl in the Given solution:

We know that Molarity of a solution = Moles of Solute / Volume of Solution(in L)

Molarity = 0.382 / 2

Molarity = 0.191 M

Write the net ionic equation for this precipitation reaction. Include physical states. ( NH 4 ) 2 CO 3 ( aq ) + Ca ( ClO 4 ) 2 (

Bad White [126]

Answer:

The net ionic equation:

$Ca^{2+}(aq)+CO_{3}^{2-}(aq) \rightarrow CaCO_{3}(s)$

Explanation:

The given chemical reaction is as follows.

$(NH_{4})_{2}CO_{3}(aq)+Ca(ClO_{4})_{2}(aq) \rightarrow CaCO_{3}(s)+2NH_{4}ClO_{4}(aq)$

The total ionic equation is as follows.

$2NH_{4}^{+}(aq)+ CO_{3}^{2-}(aq)+Ca^{2+}(aq)+2ClO_{4}^{-}(aq) \rightarrow CaCO_{3}(s)+2NH_{4}^{+}(aq)+2ClO_{4}^{-}$

Similar ions on the both sides of the reaction will be cancelled.

The remaining reaction is

$Ca^{2+}(aq)+CO_{3}^{2-}(aq) \rightarrow CaCO_{3}(s)$

Therefore, the net ionic reaction is as follows.

$Ca^{2+}(aq)+CO_{3}^{2-}(aq) \rightarrow CaCO_{3}(s)$

1 μL = 10^-6 L by definition

So...
82 μL = 82x10^-6 L = 8.2x10^-5 L
