¿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 1

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.

Explanation:

Average the numbers

Add the two masses together.

6.01512+ 7.01600= 13.03112

Then divide by 2, we divide by 2 because that is how many #'s we are given.

Answers

Answer:

The word gentle traces back to the Latin word gentlis, meaning “of the same clan,” and at first the world was used to describe people belonging to distinguished families, who were seen as courteous and noble. Nowadays you’re more likely to hear the word used to refer to things that are calm, moderate, and without harshness.

(X + Z -> gas + solution)

Answers

mass of the gas = 10 g

Further explanation

The law of conservation of mass :

In a closed / isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.

Reaction

How are convalent molecules named?

Answers

Covalent compounds are named by using numerical prefixes to identify the number of atoms in the molecule. E.g. Mono, Di, tri, tetra, etc.

In the naming, never use mono- for the first element.

The first element keeps its name.

The second element always end in the suffix -ide.

Drop the double vowel for the prefix and the element of the second element in the compound.

The direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers.

What is food chain?

The sequence of events within an ecosystem known as a "food chain" occurs when one live organism eats a different organism, which is then eaten by a larger organism. A food chain is created by the transfer of energy as well as nutrients from one creature to another at various trophic levels. A food web is comprised of numerous linked food chains.

The feeding habits or connections between living things are also explained by the food chain. Trophic level is the term used to describe the orderly phases in a food chain, from producers from the bottom through primary, secondary, and tertiary consumers. A trophic level is any position along a food chain.  A food web and a food chain are similar, but a food web seems far bigger. The direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers.

Therefore, the direction of energy flow in simple food chain is always sun=> plants( producers)=> primary consumers=> secondary consumers=> tertiary consumers.

whats the balanced chemical equation for the standard formation reaction of solid glucose, where everything can only have 1 mole with physical states.

Answers

Answer:

6C(s) + 6H2(g) + 3O2(g) --------------------> C6H12O6(s).

Explanation:

One of the examples under the type of sugar; monosaccharide(simple sugar) is the glucose. Glucose(with IUPAC name as D-glucose) as a monosaccharide (simple sugar) has the molar mass of 180.156 g/mol and a Melting point of 146 °C.

Thus, the unbalanced chemical reaction for the formation of glucose is given below;

C(s) + H2(g) + O2(g) --------------------------> C6H12O6(s) ΔH°f = -1273.1KJ/mol.

The balanced chemical reaction for the formation of one mole of glucose is given as;

6C(s) + 6H2(g) + 3O2(g) --------------------> C6H12O6(s).

The balanced chemical equation for the standard formation reaction of solid glucose is: [tex]\mathbf{6C_{(s)} + 6H_{2(g)} +3O_2_{(g)} \to C_6H_{12}O_{6} _{(s)} \ \ \ }[/tex]

Glucose is a simple sugar of a class of carbohydrates known as monosaccharides. It is the principal metabolite for energy production in the human body.

The formation of solid glucose [tex]\mathbf{C_6 H_{12} O_6_{(s)}}[/tex] occurs by the reaction of carbon, hydrogen, and oxygen.

The reaction formation of the solid glucose is:

[tex]\mathbf{C_{(s)} + H_{2(g)} +O_2_{(g)} \to C_6H_{12}O_{6} _{(s)} \ \ \ \Delta H_f^0= -1273.1 \ kJ/mol}[/tex]

Now, the balanced chemical equation can be expressed as follows;

[tex]\mathbf{6C_{(s)} + 6H_{2(g)} +3O_2_{(g)} \to C_6H_{12}O_{6} _{(s)} \ \ \ }[/tex]

Orange juice is mixture.

Answer:

[tex]\boxed {\boxed {\sf Mixture}}[/tex]

Explanation:

An element is pure and all the atoms have the same atomic number. An element has a symbol and can be found on Periodic Table of Elements.

A mixture is created when two or more substances are combined physically.

Orange juice can't be found on the Periodic Table of Elements. Orange juice is made up of many different substances/ingredients, like water, sugar, and juice from the orange.

Therefore, orange juice is considered to be a mixture. More specifically, a homogenous mixture because it is uniform. (*applies to pulp-free orange juice). If it has pulp, it would be a heterogenous mixture.

What is atom?

The smallest unit of matter that may be split without producing electrically charged particles is the atom. It is also the smallest piece of substance with chemical element-like characteristics. As a result, the atom serves as the fundamental unit of chemistry.

Space makes up the majority of an atom. The remainder is made up of a cloud of electrons with negative charges around a positive-charged nucleus made up of protons and neutrons. Compared to electrons, that are the lightest positive ions in nature, the nucleus is tiny and dense. A particle has a nucleus that contains 10 protons and around the outside it has 8 electrons, the overall charge of the particle is +2.

NaCl + H2O → NaHCO3 +CO2 + HCl


CO2 +H2O + NaCl → NaHCO3 + HCl


NaHCO3 + HCl → CO2 + H2O + NaCl


HCl + NaCl + H2O → NaHCO3 +CO2

Answers

The balanced chemical equation :

NaHCO₃ + HCl → CO₂ + H₂O + NaCl

Further explanation

A balanced chemical reaction shows that the number of atoms of the reactant and the number of atoms of the product is the same

When baking soda (NaHCO3) reacts with hydrochloric acid (HCl), carbon dioxide bubbles (CO2) are created, along with water (H2O) and sodium chloride (NaCl) .

This statement shows that

Reactants (located to the left of the reaction)

Baking soda (NaHCO₃) and Hydrochloric acid (HCl)

product (located to the right of the reaction)

Carbon dioxide(CO₂),water  (H₂O) and Sodium chloride (NaCl).

So the reaction :
