The proton-proton chain ____ (A) combines two hydrogen nuclei to produce a single helium nucleus and energy.(B) splits a helium

emmainna [20.7K]

Answer:

(C) is the mechanism that increases the temperature between the photosphere and corona of the sun.

Explanation:

When a stars is converted from hydrogen to helium then this is known as proton -proton chain reaction.Due to this reaction the temperature between corona of the sun and photosphere increases.The main reason for increasing the temperature is exothermic reaction.

So the option C is correct.

(C) is the mechanism that increases the temperature between the photosphere and corona of the sun.

Explain the changes in kinetic energy as a substance is heated to its melting point, and how these changes affect intermolecular

Drupady [299]

The more solid a substance is, the less kinetic energy there is. This is because there is not a lot of space for the atoms in the solid state to move. However, in the gaseous state, the atoms are far apart with plenty of space, this lets them create a lot more kinetic energy. Solids have a lot more intermolecular forces because the atoms are together. The IMF (intermolecular force) is what lets the atoms/molecules stick together. In the solid state, all the atoms are stuck together with little to no room in between. In the liquid state, it has a lot of IMF but is weaker then the IMF in the solid state. This is why you have so much resistance when you try to move through water. In the gaseous state, there is little to no IMF because the atoms are all so far apart. This makes it easier for everyone to move around.

To answer your question more directly: As the substance is heated to its melting point, there is an increase in kinetic energy, but decrease in intermolecular forces.

What can you infer if the fossil of a marine organism is found in an area that is now dry land?

Deffense [45]

Answer:

Fossils also help us to infer why dinosaurs and other organisms became extinct. Fossils tell us that there was a mass extinction at the time of the dinosaurs. They died out about 65 million years ago, along with more than half of all the other animal and plant species. ... Without plants, dinosaurs could not survive.

Explanation:

hope it will help you have a great day bye and Mark brainlist if the answer is correct

Is SO3 ionic or ionic using the stock system or molecular

vampirchik [111]

Answer:

Molecular

Explanation:

Using the rules for the nomenclature for naming binary covalent (molecular) compounds, the compound SO3 is named sulfur trioxide. The prefix tri- indicates that the oxygen has a subscript of 3 and that a molecule of sulfur trioxide has three oxygen atoms.
