¿Por qué un trozo de sal común es frágil y se puede romper fácilmente cuando se le somete a una fuerza y no ocurre lo mismo con un trozo de metal que se deforma antes de romperse?
Answers
Answer:
Explanation:
La sal común es un compuesto iónico, es decir que sus átomos (Na y Cl) están unidos entre sí por fuerzas electrostáticas, y el metal está unido entre sí por uniones metálicas. La naturaleza de estas uniones es diferente y en base a las fuerzas de atracción que hay entre los átomos en compuestos con este tipo de uniones, la propiedades físicas generales serán diferentes.
En el caso de los metales, los átomos metálicos están colocados unos sobre otros de forma ordenada, pero no fijamente retenida, y los electrones de valencia están delocalizados a través de todo el cristal metálico. Por esta razón, cuando se le aplica una fuerza a un metal, estos átomos pueden deslizarse unos sobre otros. Ésta es la propiedad que le da a los metales su maleabilidad.
En el caso de los compuestos iónicos, los aniones y cationes que lo componen están ordenados en el cristal de una forma más rígida y por eso cuando se les aplica una fuerza éstos compuestos se rompen mucho más fácil, ya que no pueden deformarse.

Why do atoms form bonds with other atoms?
SELECT ALL THAT APPLY
a
To ensure that both atoms in the bond have eight total
electrons.
b To obey the octet rule.
С
To fill the outer electron shells of both atoms.
d
To achieve a more stable electron configuration for both
atoms.
Answers
The smallest unit that combines chemically or physically to form molecules and compounds is called an atom. They are composed of electrons and protons and neutrons in the nucleus.
The correct answer is:
Option d. To achieve a more stable electron configuration for both atoms.
This can be explained as:
Atoms do not always bond to complete eight electrons in their shells.Atoms do not react to follow the octet rule.Electrons don't need to be filled in the shells of atoms of both the shells as some atoms lose electrons too.Therefore to achieve stable configuration atoms bond with other atoms.

Mr. Krabbs wants to make Bikini Bottoms a nicer place to live. He has created a
new sauce that he thinks will reduce the amount of bodily gas that comes out after
eating krabby patties from the Krusty Krab. He brings in 100 customers that
always have gas problems. He has 50 of them (Group A) eat krabby patties with
the new "Gas-free" sauce. The other 50 (Group B) eat krabby patties with sauce
that looks just like the Gas-free sauce but is really the old sauce with food

Answers
Answer:
The hypothesis is that the new sauce used in hamburgers will be able to reduce the incidence of body gases in customers.
Explanation:
A hypothesis is an assumption about a specific topic that is being researched. In the case shown in the question above, Krusty Krab believes that the new sauce he wants to use in hamburgers is capable of reducing the amount of body gases created by the body. Krusty Krab wanted to do scientific research where he analyzed the efficiency of this new sauce, but he assumes that the new sauce is efficient in reducing the creation of these gases.

The chemical equation represents a reaction between ammonia and oxygen to form nitrogen monoxide and water. 4 N H 3 ( g ) + 5 O 2 ( g ) → 4 NO ( g ) + 6 H 2 O ( g ) What is the limiting reagent when a 4.50 g sample of ammonia is mixed with 15.80 g of oxygen?
Answers
The limiting reagent : NH₃
Further explanationA method that can be used to find limiting reactants is to divide the number of moles of known substances by their respective coefficients, and small or exhausted reactants become a limiting reactant
Reaction
4NH₃(g)+5O₂(g)⇒4NO(g)+6H₂O(g)
mol NH₃ :
[tex]\tt \dfrac{4.5}{17}=0.265[/tex]
mol O₂ :
[tex]\tt \dfrac{15.8}{32}=0.494[/tex]
mol ratio
NH₃ :
[tex]\tt \dfrac{0.265}{4}=0.06625[/tex]
O₂ :
[tex]\tt \dfrac{0.494}{5}=0.0988[/tex]
Limiting reactants : NH₃ (smaller ratio)
The limiting reagent when a 4.50 g sample of ammonia is mixed with 15.80 g of oxygen is NH₃
Calculation of limiting reagent:The limiting reactant refers to the reactant that gets consumed first in a chemical reaction and thus it limits how much product can be created or developed. A method that can be used to determine limiting reactants that to divide the number of moles by their respective coefficients.
So,
For mol NH₃ :
[tex]= 4.5\div 17[/tex]
= 0.494
For mol O₂ :
[tex]= 15.8 \div 32[/tex]
= 0.494
For mol ratio
NH₃ :
[tex]= 0.265 \div 4[/tex]
= 0.06625
O₂ :
[tex]= 0.494 \div 5[/tex]
= 0.0988
Based on the above calculations we can say that it is NH₃

how to write the ionic formula for the K1+, MnO41- pair of ions
Answers
Answer:
Ionic formula: KMnO4
Explanation:
Pottasium permanganate (KMnO4) is an ionic compound that contains a combination of pottasium cations (K+) and permanganate anion (MnO4-). The pair of ions that make up the ionic compound cancel out each other to make it neutral.
K+ (aq) + MnO4- (aq) → KMnO4 (aq)
MnO4- contains 1 atom of manganese with a (+7) charge and four atoms of oxygen with a (-2) charge each. This forms a +7 for Mn and -8 for O4, hence, a net total of -1.
Here is a model of the sun earth system at a certain point in earths orbit around the sun based on the model which statement best explains my point is is experiencing summer
Answers
Answer:
the earth is tilted towards the sun
Explanation:
In the context, there is a sun and earth system and at a certain point when the earth is moving in its orbit around he sun, some point on the earth experiences the summers season. This is because at this point of the earths revolution, the point on the earth is facing the sun and is also tilted towards the sun. So at this point the sun rays fall directly at the surface. While the place which is tilted away from the sun, experiences winter season.
Answer:
Earth's northern hemisphere is tilted toward the Sun.

which of the following lists show the elements in order, from those having the least protons to those having the most protons in the atoms?
A. K, Mg, N, O
B. C, Al, P, Cl
C. Li, Be, H, He
D. Na, Ne, He, H
Answers
The elements that have least protons to those having the most protons in the atoms are:
B. C, Al, P, Cl
Protons in an atom:There is an equal number of protons and electrons in an atom. So when moving across a period in a periodic table the number of electrons increases which also shows the increases in a number of protons. So as the atomic number increases, the number of protons and electrons also increases.
Thus, the order of elements having least to greatest protons are:
C, Al, P, Cl
C has 6 atomic number, Aluminium has 13 atomic number , Phosphorus has 14 atomic number and atomic number of chlorine is 17.
Thus, option B is correct.

please show the work :(What is the estimated force applied to the box if the acceleration is .40 m/s2?
force (N) acceleration (m/s2)
10 .20
? .40
Answers
Answer:
20N
Explanation:
Given parameters:
Force(N) Acceleration(m/s²)
10 0.2
? 0.4
Unknown:
The force applied when the acceleration is 0.4m/s²
Solution:
From newton's second law of motion;
Force = mass x acceleration
Since we are using the same box, let us find the mass of the box;
Force = mass x acceleration
10 = mass x 0.2
mass = [tex]\frac{10}{0.2}[/tex] = 50kg
Now,
The force in the second instance will be;
Force = 50 x 0.4 = 20N

Ayala is making salad dressing. She mixes oil and
vinegar in a blender until a smooth consistency is
formed. Explain whether this is a heterogeneous or a
homogeneous mixture and why.
Answers
Answer:
A heterogeneous mixture
Explanation:
A heterogeneous mixture is a mixture that is not uniform in composition. This means that we can tell that there is more than one component in the mixture. An example of a heterogeneous mixture would be milk and cereal.
The opposite is a homogeneous mixture, which is uniform in composition. An example of a homogeneous mixture is air. There are many different particles surrounding us, but we can't tell.
A salad dressing that consists of oil and vinegar is another example of a heterogeneous mixture. Its consistency is smooth, but oil and vinegar can't dissolve each other, which means that we will see droplets of oil and vinegar. Since we can tell that it contains these components, this is a heterogeneous mixture.
Answer:
Sample Response: A homogeneous mixture can only form when one of the substances can dissolve the other one. Oil and water cannot dissolve each other, so they must form a heterogeneous mixture with small particles of vinegar dispersed throughout the oil, yet not dissolved.
