Which factor has the greatest effect on the melting point of a crystalline solid

Answers

The answer is: the type of bonding among the particles.

For example, calcium oxide (CaO) has ionic bonds between calcium cations (Ca²⁺) and oxygen anions (O²⁻).

Because it has strong ionic bonds, it has high melting point (around 2600°C).

Ionic bond is the electrostatic attraction between oppositely charged ions (cations and anions).

Amount of energy required to change 1 gram of material from the solid to the liquid state at its melting point

Inter-molecular forces. The greater the attraction between particles the more energy required to break the forces or "melt" them.

Reactant X contains 199.3 J of chemical energy. Reactant Y contains 272.3 J of chemical energy. Product W contains 41.9 J of chemical energy. If the reaction loses 111.6 J of chemical energy as it proceeds, how much chemical energy must product Z contain? 318.1 J 429.7 J 541.3 J 625.1 J

Answers

Answer : The correct option is, 318.1 J

Solution :

The given chemical reaction will be,

$X+Y\rightarrow W+Z+Energy$

In this reaction, X and Y are the reactants and W and Z are the products.

As we know that the energy remains conserved during the chemical reaction.

So,

Sum of energy of product = Sum of energy of reactant

$W+Z+Energy=X+Y\n\n41.9J+Z+111.6J=199.3J+272.3J\n\nZ=318.1J$

Therefore, the amount of chemical energy of product Z contain will be, 318.1 J

Answer:

318.1 J

Explanation:

The reaction given is:

X + Y → W + Z

The chemical energy of the reaction (ΔU), is the variation of the chemical energy, so is the chemical energy of the products (UW and UZ) less the chemical energy of the reactants (UX and UY).

If the reaction loses the chemical energy, it must be negative, and the chemical energy that a substance contains, is positive.

ΔU = (UW + UZ) - (UX + UY)

-111.6 = (41.9 + UZ) - (199.3 +272.3)

-111.6 = 41.9 + UZ - 471.6

- UZ = - 429.27 + 111.6

-UZ = - 318.1

UZ = 318.1 J

as a result of the gold foil experiment it was concluded that an atom (1) contains protons, neutrons, and electrons(2)contains a small, dense nucleus(3)has positrons and orbitals (4)is a hard and invisible sphere

Answers

It showed that the atom contains a small dense nucleus. The reason why this can be concluded is that the experiment showed that alpha particles can for the most part pass right through the foil. This showed that the nucleus of the atom is very small and takes up a very small portion of the size of an atom since the nucleus is what would reflect the alpha particle. If atoms were not mostly empty space, the alpha particles would have been bounced back and the opposite of what was observed would have happened (all or at least the majority would be bounced back instead the majority getting through with only a small portion being reflected back).

I hope this helps. Let me know in the comments if anything is unclear.

Final answer:

The gold foil experiment, conducted by Ernest Rutherford, discovered the existence of a small, dense nucleus within an atom, making answer (2) the correct one.

Explanation:

The gold foil experiment was conducted by Ernest Rutherford and led to the discovery of a small, dense nucleus within the atom. This means that the correct answer to your question is (2) contains a small, dense nucleus. Prior to this experiment, the widely accepted model was the 'plum pudding' model, which had negatively charged electrons embedded within a positively charged sphere. The gold foil experiment upended this model as it was discovered that most alpha particles passed through the gold foil undeterred, but a small fraction was deflected at large angles, suggesting that a tiny but dense packet of positive charge — identified as the nucleus — existed in the center of the atom. This discovery led to the formation of the Rutherford atomic model.

What types of epithelial cells would you expect to find in an area of the body where diffusion of nutrients needs to occur?1) Cuboidal
2) Columnar
3) Squamous

Answers

The type of epithelial cells that would be found in an area of the body where diffusion of nutrients needs to occur is squamous.

Epithelial cells refer to the cells that are vital in the lining of the surface of the body. Epithelial cells can be found on the blood vessels, skin, and urinary tract.

It should be noted that epithelial cells are important as they act as a protective barrier and help in stopping viruses from getting inside the human body.

It should be noted that squamous can be found in an area of the body where diffusion of nutrients needs to occur. They're flat cells and they are usually thin and resembles the scale of fishes.

In conclusion, squamous can be found on the surface of the skin.
