Tipo de enlace en los compuestos. Compuesto /Electronegatividad Elemento 1/Electronegatividad Elemento 2/ Diferencia de electronegatividad (resta) Tipo de enlace CO2 KCl H2O

Answers

Answer:

Tipo de enlace enlace en CO2 - Covalente

Tipo de enlace enlace en KCl - iónico

Tipo de enlace enlace en H2O: enlaces covalentes y de hidrógeno

Electronegatividad de CO2 - Diferencia en electronegatividad de carbono (EN = 2.5) y oxígeno (EN = 3.5) = 3.5 - 2.5 = 1

Diferencia en electronegatividad de KCl = 3,2 -0,8 = 2,4

Diferencia en electronegatividad de H2O = 3.5 -2.1 = 1.4

When 1 mol of methane is burned at constant pressure, −890 kJ/mol of energy is released as heat. If a 1.67 g sample of methane is burned at constant pressure, what will be the value of ∆H

Answers

Answer:

[tex]\Delta H=-92.7kJ[/tex]

Explanation:

Hello there!

In this case, according to the given information, we can infer that 890 kJ of energy are released when 1 mole of methane is burned; however, to find the total heat when 1.67 grams are burned, we first need to calculate the moles in this mass of methane:

[tex]1.67gCH_4*\frac{1molCH_4}{16.04gCH_4}=0.104molCH_4[/tex]

And thus, for calculating the resulting ∆H, we proceed as follows:

[tex]\Delta H=-890kJ/mol*0.104mol\\\\\Delta H=-92.7kJ[/tex]

Answers

Answer:

Zirconium is a silver-gray transition metal, a type of element that is malleable and ductile and easily forms stable compounds. It is also highly resistant to corrosion. It is commonly used in corrosive environments. Zirconium alloys can be found in pipes, fittings, and heat exchangers, according to Chemicool.

Explanation:

Answer: Today this element is widely used, as zircon, as Zirconium oxide and as the metal itself. Zirconium is to be found in ceramics, foundry equipment, glass, chemicals, and metal alloys. Zircon sand is used for heat-resistant linings for furnaces, for giant ladles for molten metal, and to make foundry moulds.

Which of the following is a correct statement about water? (3 points)

Hydrogen bonding causes water to be strongly cohesive.
Hydrogen bonding causes water to have a low surface tension.
Water is a universal solvent because polar and nonpolar solutes can dissolve in it.
Water is less dense as a liquid than as a solid because of changes in bond structure.

Answers

Answer:

A: Hydrogen bonding causes water to be strongly cohesive.

Explanation:

Water has a high surafce tension. Hence droplets of water

Water cannot dissolve non polar substances like oil; only polar

Water is actually less dense in solid form :)

Hydrogen bonding causes water to be strongly cohesive.

This sticking together of like substances is called cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be more or less cohesive. Hydrogen bonds cause water to be exceptionally attracted to each other. Therefore, water is very cohesive.

Cohesion

Cohesion, also called cohesive attraction or cohesive force, is the action or property of like molecules sticking together, being mutually attractive. It is an intrinsic property of a substance that is caused by the shape and structure of its molecules, which makes the distribution of surrounding electrons irregular when molecules get close to one another, creating an electrical attraction that can maintain a microscopic structure such as a water drop. In other words, cohesion allows for surface tension, creating a "solid-like" state upon which light-weight or low-density materials can be placed.

When calcium metal is placed in water a vigorous single replacement rection occurs, releasing hydrogen gas. What will happen to the pH of the solution that forms as this chemical reaction proceeds

Answers

Answer:

The pH of the solution increases

Explanation:

One of the properties of metals is that they react with water to yield hydrogen gas and the hydroxide of the metal.

Calcium is a metal in group two of the periodic table and also undergoes such reaction.

The equation of the reaction is;

Ca(s) + 2H2O(l) -----> Ca(OH)2(aq) + H2(g)

Since Ca(OH)2 is alkaline, the pH of the solution increases.

When a 0.860 g sample of an organic compound containing C, H, and O was burned completely in oxygen, 1.64 g of CO2 and 1.01 g of H2O were produced. What is the empirical formula of the compound?

Answers

Answer:

C₂H₆O

Explanation:

Empirical formula is the simplest ratio of atoms present in a molecule. To solve this question we must find the moles of C, H and O in order to find the simplest ratio of this atoms.

To solve this question we must find the moles of C from CO2, moles of H from H2O and moles of O from the difference of masses of C and H and the sample:

Moles C:

1.64g CO2 * (1mol / 44g) = 0.03727 moles CO2 * (1mol C / 1mol CO2) = 0.03727 moles C

0.03727 moles C * (12g / mol) = 0.4473g C

Moles H:

1.01g H2O * (1mol / 18g) = 0.05611 moles H2O * (2mol H / 1mol H2O) =

0.1122 moles H

0.1122 moles H * (1g / mol) = 0.1122g H

Moles O:

0.860g - 0.1122g H - 0.4473g C = 0.3005g O * (1mol / 16g) =

0.01878 moles O

The ratio of the moles of atoms regard to the moles of O (Lower number of moles) is:

C = 0.03727 moles C / 0.01878 moles O = 1.98 ≈ 2

H = 0.1122 moles H / 0.01878 moles O = 5.97 ≈ 6

O = 0.01878 moles O / 0.01878 moles O = 1

Empirical formula is:

C₂H₆O

REALIZAR LA MASA MOLECULAR DE LOS SIGUIENTES COMPUESTOS HIDROXIDO DE MAGNESIO = Mg(OH)2 ACIDO CARBONICO = H2CO3 GLUCOSA= C6H12O6

Answers

Answer:

Mg(OH)2 = 58.321g/mol

H2CO3 = 62.026g/mol

C6H12O6 = 180.156g/mol

Explanation:

Para hallar la masa molecular debemos, primero, identificar las moles de cada átomo presentes en una mol de una molécula. Por ejemplo, para el hidróxido de magnesio:

Mg = 1mol

O = 2mol

H = 2mol

Ahora, debemos hacer la suma del peso molecular de todos estos átomos. Esto es:

Mg = 1mol * (24.305g/mol) = 24.305g/mol

O = 2mol * (16g/mol) = 32g/mol

H = 2mol* (1.008g/mol) = 2.016g/mol

El peso molecular del hidróxido de magnesio es:

24.305g/mol + 32g/mol + 2.016g/mol = 58.321g/mol

Ácido Carbónico:

H = 2mol * (1.008g/mol) = 2.016g/mol

C = 1mol * (12.01g/mol) = 12.01g/mol

O = 3mol * (16g/mol) = 48g/mol

Masa molar = 62.026g/mol

Glucosa:

C = 6mol * (12.01g/mol) = 72.06g/mol

H = 12mol * (1.008g/mol) = 12.096g/mol

O = 6mol * (16g/mol) = 96g/mol

Masa molar = 180.156g/mol
