Two samples of solids have similar reactivity with acids and similar densities. Their masses
and volumes, however, are not at all similar. Is it possible that these are the same
substance? (1 point)
O. No, it is not possible because they have different extensive properties.
O Yes, it is possible because they have similar intensive properties.
O Yes, it is possible because they have similar extensive properties.
O No, it is not possible because they have different intensive properties.
Answers
They may be the same substance even though they have different volumes and masses.
Intensive properties are the properties are characteristic a substance. Intensive properties are those properties of a substance that can be used to describe the substance.
We can see that the substances have similar reactivity and similar density. This means that they may be the same substance even though they have different volumes and masses.
The correct option is; "Yes, it is possible because they have similar intensive properties."

Is this an example of an endothermic or exothermic reaction? Why?
Answers
Answer:
Explanation:
Exothermic: the surrounds feel warmer. A wood fire stove is a good example of an exothermic reaction. You can feel the heat on your hands. It's exothermic.
Endothermic is exactly the opposite. The reaction takes place, but the heat comes from the surroundings. When you touch something that goes through an endothermic reaction, it feels much cooler.
This reaction, just by definition is endothermic.

A small container of perfume is opened in a classroom. Soon every student in the room smells the perfume. Explain this in terms of molecules.
Answers
When perfume or cologne is sprayed into the air, it turns into a gas and its particles mix with other air particles that quickly move around the room. This is because gas is the least dense of the three states of matter. It moves quickly into any space or volume because it has the least density. This is called diffusion, when molecules or particles move from areas with high concentration to low concentration areas.

How many grams of ammonia are produced from 6 moles of nitrogen?
Answers
Answer: The equation is 3H2 + N2 → 2NH3
If 6 moles of H2 gas react with N2 (assuming all reactants react)
6 * 2/3 moles of ammonia must be produced.
Therefore 4 moles of ammonia can be produced.
Since it is a gaseous equation (all reactants/products are gases), we can just assume that the Mr of the gases do not affect the amounts of the reactants or the products.

what is the three-dimensional coordination number of the face-centered cubic arrangement?
Answers
The three-dimensional coordination number of the face-centered cubic arrangement has a coordination number of 12 and contains 4 atoms per unit cell.
What is coordination number ?The coordination number, also known as ligancy, of a central atom in a molecule or crystal is the sum of all the atoms, molecules, or ions that are linked to it. This value is used in crystallography and materials science. A ligand is the ion, molecule, or atom that surrounds the center ion, molecule, or atom.
The number of atoms, ions, or molecules that a central atom or ion bears in a complex or coordination compound or in a crystal as its near neighbors is known as the coordination number, also known as ligancy.
In contrast to oxidation state, which is a number assigned to an element in chemical combination and represents the number of electrons lost or gained by an atom of that element in the compound, co-ordination number is the number of co-ordination bonds with which the ligands are bound to the central ion.
Thus, the face-centered cubic arrangement has a coordination number of 12 and contains 4 atoms per unit cell.

B) Gases have the greatest kinetic energy. C) Energy is removed in the change from a liquid to a gas. D) Energy is added to change from a solid to a liquid state. E) In a solid, particles are so closely packed that they can only vibrate in place.
Answers
The statements which accurately describe the particles in differing states include:
Gases have the greatest kinetic energy.Energy is added to change from a solid to a liquid state. In a solid, particles are so closely packed that they can only vibrate in place.Gases have the greatest kinetic energy which explains why its particles
move very rapidly and randomly when compared to other states of matter.
Conversion from solid to liquid or liquid to gas requires more energy being
added.
The particles in solids are tightly packed with very restricted movements
which is why they are able to vibrate at a place.

The atomic mall mass is an element depends upon the.
Answers
Answer:
Mass and relative abundance of each isotope of that element
The atomic mass of element has been dependent on mass of each isotopes and their abundance in nature.
The atomic mass has been the mass of neutrons and protons of the element. There has been the presence of the isotopes of the elements, with varying abundance, and varying atomic masses.
The atomic mass of the element has been the relative average atomic mass of the element with respect to the mass of the isotopes and their percent abundance.
The average atomic mass (amu) has been given by:
[tex]amu=M_1A_1\;+\;M_2A_2[/tex]
Where, [tex]M_1A_1[/tex] has been the atomic mass and abundance of isotope 1.
[tex]M_2A_2[/tex] has been the atomic mass and abundance of isotope 2.
Thus, the average atomic mass has been dependent on mass of each isotopes and their abundance in nature.
