Consider the reaction 2Al(OH)3(s)→Al2O3(s)+3H2O(l) with enthalpy of reaction ΔHrxn∘=21.0kJ/mol What is the enthalpy of formation of Al2O3(s)?
Answers
The enthalpy of formation of the solid Al2O3(s) is -1675.6 kJ/mol .
Using the relation;
ΔH°rxn = ∑ΔH°fproducts - ∑ΔH°freactants
We know that;
ΔH°f H2O(l) = -285.8 kJ/mol
ΔH°fAl(OH)3(s) = -1315 kJ/mol
ΔH°fAl2O3(s) = ?
Substituting values;
21.0kJ/mol =[ (ΔH°fAl2O3(s) ) + 3( -285.8 kJ/mol)] - 2 ( −1277kJ/mol)
21.0kJ/mol = (ΔH°fAl2O3(s) ) + 1696.6 kJ/mol
ΔH°fAl2O3(s) = 21.0kJ/mol - 1696.6 kJ/mol
ΔH°fAl2O3(s) = -1675.6 kJ/mol

Rocket engines can be fueled by liquid hydrogen. The liquid hydrogen reacts with liquid oxygen, producing water vapor and releasing an enormous amount of energy.
Consider the following reaction:
2 molecules of hydrogen (H2) react with 1 molecule of oxygen (O2) to produce some amount of water (H2O).
To find the amount of water produced, first determine the number of each type of atom in the products.
Hint: During a chemical reaction, atoms are not created, destroyed, or changed from one chemical element to another.

How does this simulation demonstrate the Law of Universal Gravitation?
Answers
Hope it helps :)
Answer:
The Law of Universal Gravitation states that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them. This simulation uses the sun to attract other planets. The greater the distance between the objects the greater gravitational pull.

Students were investigating how static electricity can cause objects to move. They decided to take pictures of what they observed.Write a scientific explanation about the forces that can affect objects when the objects are not touching. Make a claim and state your evidence.
Answers
Answer:
Answer: Think of a thunderstorm, sometimes it depends on the magnitude of a push or pull to move an object even without touching it. When a object is sitting still, it means the normal force and the gravitational force are balanced, when one force becomes greater, it takes over.

Answers
Answer:
a. Solar
Explanation:
Solar energy causes water to evaporate, which is the driving force of the water cycle. Water from the ocean evaporates and comes back down as rain and it gives life to the Earth and so it continues.
Explanation : The sun provides its solar energy which causes liquid and frozen water to evaporate into water vapor. This water vapor rises into the sky to form clouds, and from there on the clouds move over the globe and drop rain and snow, and from there on the water cycle continues.
