Match the following descriptions with the correct polysaccharide, note if you answer any part of this question incorrectly a sig

n read x will appears if one or more of the polysaccharides placed in correctly This polysaccharide is the storage form of glucose in the human body. This polysaccharide is the structural component of plant cell walls and cannot be digested by humans. The glucose units in this polysaccharide are joined only by 1,4glycosidic bonds glycogen The glucose units in this polysaccharide are joined by beat.1,4-glycosidic bonds Those two branched polysaccharides contain both alpha 1.4 and alpha 1,6-glycosidic bonds These two polysaccharides make up starch, the storage form of glucose in plants

Answer:

Glycogen. Cellulose. Amylose. Cellulose. Amylopetin and Glycogen. Amylopetin and Cellulose.

Explanation:

Glycogen is the form that glucose is stored in human body.

Cellulose is the structural part of plant cell walls and human cannot digest it.

Amylose is the polysaccharide linked mainly by the the bonds of \alpha 1,4 glycosidic.

Cellulose is an unbranched polysaccharide linked mainly by the bonds of  \beta 1,4 glycosidic.

Amylopetin and Glycogen are branched polysaccharides linked by the bonds of \alpha 1,4 glycosidic and \alpha 1,6 glycosidic.

Amylopetin and Cellulose are mainly stored in plants.

Study the reaction. NO(g) ⇌ 12N2(g) + 12O2(g) ΔH = −90.3 kJ Which statement about the reaction is correct? A) The reverse reacti
lozanna [386]

Answer:

The forward reaction is an exothermic reaction.

Explanation:

An exothermic reaction is one in which energy is released, usually in the form of heat hence the enthalpy of the reaction is negative. When a reaction exothermic, the energy of the reactants is greater than the energy of the products hence the excess energy is given out as heat. The reactants lie at a higher energy level in the reaction profile compared to the products.

When we look at the reaction given in the question, NO(g) ⇌ 12N2(g) + 12O2(g) ΔH = −90.3 kJ , we can easily see from the thermochemical reaction that the forward reaction is exothermic, energy is released by the reaction system as evidenced by the negative enthalpy of reaction.

Which properties are characteristic of metalloids?
Setler [38]
<h2>Answer:</h2>

<u>The right option is</u><u> (C) intermediate conductivity and a high melting point</u>

<h2>Explanation:</h2>

Metalloids usually look like metals but behave largely like nonmetals. Metalloids are shiny, brittle solids with intermediate good electrical conductivity. Their properties lie between metals and non metals. All metalloids exist as solids at room temperature and they have very high melting points. The physical properties of metalloids are more likely to be metallic, but their chemical properties tend to be non-metallic

4. Cuál es la aplicación de las reacciones de óxido-reducción en la vida diaria y en la industria?
12345 [234]

Answer:

<em>Dentro de las aplicaciones de la óxido-reducción se pueden encontrar:</em>

  1. <u><em>La obtención del aluminio a partir de la alúmina y la electrolisis.</em></u>
  2. <u><em>La obtención de cloro, hidrógeno e hidróxido de sodio a partir del cloruro de sodio y la electrolisis.</em></u>
  3. <u><em>La combustión interna de un motor a gasolina u otro combustible fósil.</em></u>
  4. <u><em>Las termoeléctricas, las cuales para generar energía realizan combustión de carbón.</em></u>
  5. <u><em>La galvanoplastia, donde para evitar la corrosión de un metal se recubre con otro metal más resistente, por ejemplo: el recubrimiento del acero con zinc.</em></u>
  6. <u><em>La pilas o baterías de las cuales se obtiene energía química</em></u><em>.</em>

Explanation:

<em>Como puedes ver en la respuesta, la óxido-reducción tiene diversas aplicaciones en la vida moderna, desde todos los tipos de combustión los cuales sirven para brindar energía o movilizarte, hasta todas las funciones que se le ha dado a la electrolisis y a la obtención de la energía por medios químicos, incluso se puede considerar una aplicación de la óxido-reducción la incorporación de antioxidantes en los alimentos, los cuales disminuyen la velocidad de descomposición de los mismos. </em>
