A sequence of thermonuclear fusion processes inside massive stars can continue to transform the nuclei of elements such as carbo

nlexa [21]

Answer:

Iron is the element that is produced at the limit of the reaction.

Explanation:

In nuclear fusion 2 lighter nuclei are combined together into a single nucleus releasing a tremendous amount of energy in the process.

Up to fusion of iron the reaction of fusion is exothermic but when iron atom pops out the reaction becomes endothermic and it requires very high amount of energy to fuse iron atoms which is not available thus marking an end to the fusion reaction.

Briefly explain formality in solution.

Zielflug [23.3K]

Answer:

Both molarity and formality express concentration as moles of solute per liter of solution. Formality is a substance's total concentration in solution without regard to its specific chemical form. ... The formality of a solution is defined as the number of formula mass of any solute dissolved in 1 litre of solution.

When water vapor changes to a liquid what is it called

Mademuasel [1]

Answer:

$hello \: your \: answer \: is \: here.$

Explanation:

<h2>Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.</h2>

Which of the following explains the formation of the curved surface of water in the graduated cylinder shown below?

lara [203]

Answer: option D, Attractive forces form between polar water molecules and polar glass molecules in the cylinder.

Explanation:

1) The curved surface of water in the cylinder shown in the figure is named concave meniscus.

2) The situation shown reflects two forces that oppose each other.

These are the adhesive force and the cohesiive force.

3) The adhesive force is the of attraction between molecules of different substances, while the cohesive force is the attraction between molecules of the same substance.

4) Water has a strong cohesive force property in virtue of the hydrogen bonds (the particles of water tends to remain together due to the high intensity of the hydrogen bonds). This is why water form drops.

But also, there is a strong cohesive force between the polar water molecules and the polar glass molecules in the cylinder.

The concave meniscus is the result of the fact that the adhesive force between the surface of the glass cylinder and the molecules of water overcomes the cohesive force of the water molecules.
