A saturated solution of potassium chlorate is dissolved in 100g of water. If the saturated solution is cooled from 90 degrees Ce
1 answer:
Mass would crystallize out : 24 g
<h3>Further explanation </h3>Solubility is the maximum amount of a substance that can dissolve in some solvents. Factors that affect solubility
- 1. Temperature:
- 2. Surface area:
- 3. Solvent type:
- 4. Stirring process:
We can use solubility graph to solve this.
solubility KClO₃ at 90°C=52 g
solubilty KCl₃ at 60°C= 28 g
Mass would crystallize out = 52 - 28 =24 g

Answer : The moles of left in the products are 0.16 moles.
Explanation :
First we have to calculate the moles of .
Using ideal gas equation:
where,
P = pressure of gas = 1 atm
V = volume of gas = 10 L
T = temperature of gas =
n = number of moles of gas = ?
R = gas constant = 0.0821 L.atm/mol.K
Now put all the given values in the ideal gas equation, we get:
Now we have to calculate the moles of .
The balanced chemical reaction will be:
From the balanced reaction we conclude that,
As, 1 mole of react with 2 moles of
So, 0.406 mole of react with
moles of
Now we have to calculate the excess moles of .
is 20 % excess. That means,
Excess moles of =
× Required moles of
Excess moles of = 1.2 × Required moles of
Excess moles of = 1.2 × 0.812 = 0.97 mole
Now we have to calculate the moles of left in the products.
Moles of left in the products = Excess moles of
- Required moles of
Moles of left in the products = 0.97 - 0.812 = 0.16 mole
Therefore, the moles of left in the products are 0.16 moles.
Answer: A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
Explanation:
A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
Explanation:
The chart below shows monatomic ions formed when an atom loses or gains one or more electrons, and the ionic compounds they form. You can check your periodic table to see that the cations are monatomic ions formed from metals, and the anions are monatomic ions formed from nonmetals.
