Answer:
The answer to your question is below
Explanation:
Data
Volume = 1000 ml
Concentration = 2M
molecule = NaCl
Process
1.- Calculate the number of moles of NaCl
Molarity = moles/Volume
-Solve for volume
moles = Molarity x Volume (liters)
-Substitution
moles = 2 x 1
-Result
moles = 2
2.- Determine the molar mass of NaCl
NaCl = 23 + 35.5 = 58.5 g
3.- Calculate the mass of NaCl to prepare the solution
58.5 g ----------------- 1mol
x ----------------- 2 moles
x = (2 x 58.5) / 1
x = 117g
4.- Weight 117 g of NaCl, place them in a volumetric flask (1 l), and add enough water to prepare the solution.
Answer:
b) Baking soda
Explanation:
Baking soda is sodium hydrogen carbonate, NaHCO₃.
It reacts with water according to the equation
NaHCO₃ + H₂O ⇌ H₂CO₃ + NaOH
Thus, baking soda is a base because it increases the concentration of hydroxide ions in water.
<em>Water</em> is <em>neutral</em>.
<em>Lemon juice</em> is an <em>acid</em> because it contains citric acid.
An <em>insulator </em>is a substance that does not conduct electricity. Insulators are <em>neither acidic nor basic</em>.
