6 0

The reaction of potassium iodide with silver nitrate results in the formation of silver iodide as a precipitate.

<h3>What is a precipitate?</h3>

A precipitate is given as the solid deposition in the solution. It is formed as the product in the chemical reaction with the insolubility in the solution.

The reaction of KI with silver nitrate results in the formation of soluble potassium nitrate and insoluble silver iodide, which forms as the precipitate.

Thus, the reaction of potassium iodide with silver nitrate results in the formation of silver iodide as a precipitate.

What is the stoichiometric ratio between BaCl2 and NaCl

bixtya [17]

<span>BaCl2+Na2SO4---->BaSO4+2NaCl There is 1.0g of BaCl2 and 1.0g of Na2SO4, which is the limiting reagent? "First convert grams into moles" 1.0g BaCl2 * (1 mol BaCl2 / 208.2g BaCl2) = 4.8 x 10^-3 mol BaCl2 1.0g Na2SO4 * (1 mol Na2SO4 / 142.04g Na2SO4) = 7.0 x 10^-3 mol Na2SO4 (7.0 x 10^-3 mol Na2SO4 / 4.8 x 10^-3 mol BaCl2 ) = 1.5 mol Na2SO4 / mol BaCl2 "From this ratio compare it to the equation, BaCl2+Na2SO4---->BaSO4+2NaCl" The equation shows that for every mol of BaCl2 requires 1 mol of Na2SO4. But we found that there is 1.5 mol of Na2SO4 per mol of BaCl2. Therefore, BaCl2 is the limiting reagent.</span>

Maggie is solving a chemistry riddle her clue is to take the number of valence electrons in halogens and subtract it by the numb

Novay_Z [31]

The answer to the riddle Maggie is solving is 6

To determine the answer to the riddle Maggie is solving,

We will subtract the number of valence electrons in halogens by the number of valence electrons in alkali metals.

First, let us define what is meant by valence electrons

Valence electrons are those <em>electrons </em>that reside in the outermost shell surrounding an atomic nucleus.

Now, we will the determine the respective number of valence electrons in halogens as well as the number of valence electrons in alkali metals.

<em>For Halogens</em>

Halogens are the group 17 (group 7A) elements in the periodic table. Examples are Fluorine, Chlorine, Bromine etc.

Halogens have 7 electrons in their outermost shell

<em>For Alkali metals</em>

Alkali metals are the group 1 metals. Examples are Lithium, Sodium, Potassium etc.

Alkali metals have 1 electron in their outermost shell

Now, for the answer to the riddle,

Answer to the riddle = Number of valence electrons in halogens - Number of valence electrons in Alkali metals

Answer to the riddle = 7 - 1

∴ Answer to the riddle = 6

Hence, the answer to the riddle Maggie is solving is 6
