Sublimation is something like for example snow changing to water vapor without melting.
Snow is a solid and water vapor is a gas.
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)?
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

How does this simulation demonstrate the Law of Universal Gravitation?
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.

Explanation:
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.

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.
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.

Muscular System: It comprises of muscles that permit movement of the body, maintains posture and circulates blood throughout the body. So, MUSCLES are attached to bones and help them MOVE.
Circulatory System: Is system that permits blood to circulate and transport nutrients, oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment to the body. So, BONE MARROW inside the bones produce the cells inside your BLOOD.
Nervous System: It is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. So, the BRAIN tells the skeletal system when and where to move. Bones protect the ORGANS.
Digestive System: It consists of the central gastrointestinal (GI) tract and its associated accessory organs that break down food into smaller components so that nutrients can be absorbed and assimilated. So, CALCIUM help to grow and repair bones. SKELETAL SYSTEM protect the organs.
