6. La electronegatividad es una propiedad periódica que incide en un enlace químico verdadero o falso? Si es falso, porque?
Answers
Answer:
Verdadero.
Explanation:
¡Hola!
En este caso, dado que las propiedades periódicas nos hablan de un comportamiento específico sobre los elementos en la tabla periódica, resulta primeramente necesario recordar que la electornegatividad nos dice que tan fuerte es un elemento para atraer electrones de valencia de otros elementos.
De este modo, inferimos que es verdadero, ya que de hecho la electronegatividad nos define el tipo de enlace, basado en la diferencia de electronegatividades de los elementos enlazados, de acuerdo con la imagen adjunta.
Saludos!

Write a report on the implications of entropy to a Christian 500 words
Answers
The Bible provides an answer. A great amount of energy had to be expended to produce such great organization. As one scientist states the problem, energy was not enough. If you are asked to "reduce the entropy" of your room (put it in order), you certainly need to put in some effort (energy). But just adding energy is not enough. You could let loose a bull in your room, and it would expend a great deal of energy; however, that energy would not decrease but would increase the disorder of the room. Therefore, scientists know that to produce order, energy must be intelligently directed. Evolution requires that atoms and molecules assemble themselves into increasing order, but the science of thermodynamics assures us that the entire universe, when left to itself, is converting to disorder. The Apostle Paul referred to this concept when he said through inspiration that the entire earth is "subject to the bondage of decay." The original state required an intelligence to organize the complexities of the universe.
Christians, of course, have an answer to these perplexing questions: God. God is the Creator of the universe, the ultimate source of its energy and order. He created it with no entropy (no disorder). When man sinned, the universe began to increase in entropy (become more and more disordered). For Christians a discussion of energy, thermodynamics, and entropy is inspiring. These subjects invariably point us to the One who created the universe and sustains it by His power. Christians also know that His power will one day totally renew the universe and entropy will have no part in it.
Christians need never be afraid of science. God is in control of the universe and all the laws of the universe operate according to His will and design. Christians should be confident that they have the answers to the perplexing questions of nature.
Part 2
The above attitude allows christians to ignore questions that are difficult and this leads to mental complacency.
"This is gods work. I must not question or touch this". Is their motto.
When christians see difficult questions, such as entropy and creation, that is where they stop thinking and attribute it to god. They become intellectually crippled and refuse to make that one further step. It then halts progress until the shamen can integrate new knowledge into their mantra and dogma.
Science in general, tries to explain and understand and make further progress and additions to human knowledge. Christians will only try to understand what they have been taught and integrate any new knowledge when the older beliefs become untenable.
Which of the following is true of a reaction with a negative enthalpy?
O A. The enthalpy of the reactants is greater than that of the products.
B. The reaction has a negative activation energy.
C. The enthalpies of the products and reactants are both negative.
D. The enthalpy of the reactants is less than that of the products.
Answers
Answer: The statement enthalpy of the reactants is greater than that of the products is true of a reaction with a negative enthalpy.
Explanation:
A chemical reaction where energy is being released is called an exothermic reaction.
In an exothermic reaction, the value of enthalpy of reaction is negative in nature.
Also, heat is being released which means the reactants has more energy than the products due to which the value of enthalpy is negative.
Thus, we can conclude that the statement enthalpy of the reactants is greater than that of the products is true of a reaction with a negative enthalpy.

Are neutralization reactions always exothermic ?
Answers
:]
Explanation:
Neutralisation reactions are not always exothermic. ... When an acid is neutralised by an alkali the reaction is exothermic.SInce strong acids and strong bases are completely dissociated in solution, no formal bonds are being broken. The formation of two very strong covalent bonds between hydrogen and the hydroxide ion is responsible for the neutralization reaction's exothermic character.

sulfur and oxygen can react to form both sulfur dioxide and sulfur trioxide in sulfur dioxide there are 32.06 grams of sulfur and 32 grams of oxygen in sulfur dioxide there are 32.06 grams of sulfur are combined with 48 grams of oxygen
a. what is the ratio of the weights of oxygen that combine with 32.06 g of sulfur ?
b. How do these data illustrate the law of multiple proportions?
Answers
Answer:
Explanation:
In sulfur dioxide there are 32.06 grams of sulfur and 32 grams of oxygen .
In sulfur trioxide there are 32.06 grams of sulfur are combined with 48 grams of oxygen.
The ratio of oxygen which reacts with 32.06 gram of sulfur is 32: 48 .
This ratio is equal to 2 : 3.
This is in accordance with law of multiple proportion because , the ratio of mass of oxygen which reacts with constant mass of sulfur is integral ratio . Hence they are in accordance with law of multiple proportions.
Answer:
sulfur and oxygen can react to form both sulfur dioxide and sulfur trioxide in sulfur dioxide there are 32.06 grams of sulfur and 32 grams of oxygen in sulfur dioxide there are 32.06 grams of sulfur are combined with 48 grams of oxygen
a. what is the ratio of the weights of oxygen that combine with 32.06 g of sulfur?
b. How do these data illustrate the law of multiple proportions?
Explanation:
In sulfur dioxide ([tex]SO_2[/tex])
32.06 g of sulfur reacts with 32.0 g of oxygen.
In sulfur trioxide ([tex](SO_3)[/tex] 32.0 g of sulfur reacts with 48.0 g of oxygen.
So, both th ecom[pounds are made from sulfur and oxygen,
But the amount of oxygen reacts with fixed amount of sulfur that is 32.06 g and it is in proportions that is:
32.0 g : 48.0 g
=2:3.
Hence, the ratio of oxygen combines with sulfur is in the ratio of 2:3.
b.
This data illustrates the law of multiple proportions.
Because the oxygen which is combining with fixed amount of sulfur is in proportions.
In the chemical reaction between aqueous magnesium chloride and sodium metal, what chemical amount (mol) of magnesium metal can be precipitated (produced) with 12.6 mol of sodium metal?
Answers
Answer:
6.3moles
Explanation:
The balanced equation of the reaction described above between aqueous magnesium chloride and sodium metal is as follows:
MgCl2(aq) + 2Na(s) → 2NaCl(aq) + Mg(s)
From the above equation, 2 moles of sodium metal (Na) produces 1 mole of Magnesium metal (Mg)
Hence, 12.6 mol of Na will produce (12.6/2) mol of Mg.
12.6/2 = 6.3moles of Mg metal.

Silicon dioxide reacts with carbon to form silicon carbide and carbon monoxide as shown in the unbalanced reaction below. Determine the percent yield of silicon carbide if 79.1 grams of carbon reacts with an excess of silicon dioxide and 67.4 g of silicon carbide is actually recovered.
SiO2 + C → SiC + CO
Answers
*Based on the balanced equation, for every 3 moles carbon reacted, 1 mole silicon carbide is produced.
*Molar mass carbon: 12.01 g/mol
*Molar mass silicon carbide: 28.09 g + 12.01 g = 40.1 g/mol
79.1 g carbon x (1 mol carbon / 12.01 g carbon) x (1 mol silicon carbide / 3 mol carbon) x (40.1 g silicon carbide / 1 mol silicon carbide) = 88.04 g silicon carbide
