Answer:

Baking soda and vinegar react chemically because one is a base and the other is an acid. Baking soda is a basic compound called sodium bicarbonate. Vinegar is a diluted solution that contains acetic acid. ... The result of this initial reaction is two new chemicals: carbonic acid and sodium acetate.

The insoluble salts below are put into 0.10 M hydrochloric acid solution. Do you expect their solubility to be more, less, or ab
White raven [17]

Answer:

Zinc sulfide- more soluble in 0.10 M hydrochloric acid solution

Silver chloride- less soluble in 0.10 M hydrochloric acid solution

Lead iodide- same solubility in 0.10 M hydrochloric acid solution as in pure water

Silver hydroxide- same solubility in 0.10 M hydrochloric acid solution as in pure water

Explanation:

Solubility refers to the amount of a substance that dissolves in 1 dm^3 of solvent. Several factors influence the dissolution of solutes in a given solvent. Some substances dissolves at a low pH (in acid solutions) while other dissolve at a low pH (in basic solutions).

For Silver chloride, its solubility decreases in 0.10 M hydrochloric acid solution because of common ion effect when compared to its solubility in pure water.

  • Using Dimensional Analysis
  • Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.
<h3>Explanation:</h3>

<u>Step 1: Define</u>

50.0 mol H₂O

<u>Step 2: Identify Conversions</u>

Avogadro's Number

<u>Step 3: Convert</u>

<u />\displaystyle 50.0 \ mol \ H_2O(\frac{6.022 \cdot 10^{23} \ molecules \ H_2O}{1 \ mol \ H_2O} ) = 3.011 × 10²⁵ molecules H₂O

<u>Step 4: Check</u>

<em>We are given 3 sig figs. Follow sig fig rules and round.</em>

3.011 × 10²⁵ molecules H₂O ≈ 3.01 × 10²⁵ molecules H₂O

What is the molarity of a solution of 0.2 moles of Potassium Oxide
egoroff_w [7]

The molarity of a solution : 0.4 M

<h3>Further explanation</h3>

Given

0.2 moles of Potassium Oxide

500 ml of water = 0.5 L

Required

The molarity

Solution

Molarity is a way to express the concentration of the solution

Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution

\large{\boxed {\bold {M ~ = ~ \frac {n} {V}}}

Assume volume of solution = volume of water(addition of solution volume from volume Potassium Oxide is negligible

Input the value :

M = 0.2 : 0.5

M = 0.4
