Answer:
The answer to your question is Ba(OH)₂ + 2HClO₄ ⇒ Ba(ClO₄)₂ + 2H₂O
Explanation:
Reactants
Barium hydroxide
Perchloric acid
Formula
Barium hydroxide = Ba(OH)₂
Perchloric acid = HClO₄
Equation (it is a double replacement)
Ba(OH)₂ + HClO₄ ⇒ Ba(ClO₄)₂ + H₂O
Reactants Elements Products
1 Ba 1
1 Cl 2
3 H 2
6 O 9
This reaction is unbalanced
2) Balance the chemical reaction
Ba(OH)₂ + 2HClO₄ ⇒ Ba(ClO₄)₂ + 2H₂O
Reactants Elements Products
1 Ba 1
2 Cl 2
4 H 4
10 O 10
Now the reaction is balanced
Products
Ba(ClO₄)₂ Barium perchloride
2H₂O water
A student compares the boiling point of substances having different intermolecular forces. <u>Boiling points of various substances</u> is the dependent variable that student most likely use.
<h3>Does the nature of intermolecular forces present in different substance affect their boiling points?</h3>
The boiling point of a substance is proportional to the strength of its intermolecular forces, the higher the boiling point, the stronger the intermolecular forces. We can compare the strengths of intermolecular forces by comparing the boiling points of different substances.
<h3>What properties are affected by intermolecular forces?</h3>
Intermolecular forces are measured by boiling points.
Intermolecular forces increase as bond polarization increases.
Ionic > hydrogen bonding > dipole dipole > dispersion is the order of the strength of intermolecular forces (and thus their impact on boiling points).
<h3>How can you determine strong and weak intermolecular forces?</h3>
Substances with strong intermolecular forces are very attracted to one another and are held together tightly. These substances require a great deal of energy to separate, whereas substances with weak intermolecular forces are held together very loosely and have weak interactions.

Answer:
Some natural resources like sunlight and wind are found everywhere, but other natural resources are unevenly distributed. Resources like oil, coal, and natural gas are only found where conditions were favorable to grow and preserve large quantities of animal or plant matter.
Explanation:
The atomic number is 8 and the atomic mass is 16
The atomic number of the element is 8. This is because the atomic number is based on the number of protons or electrons. The atomic mass of the element is 16. This is because the atomic mass is equal to number of protons+the number of neutrons. Hope this helps.
