Answer:

Nuclear Binding Energy (Bond Energy), Higher (Greater)

Explanation:

The energy required to overcome the attraction between two bonded nuclei and their shared electrons is called Nuclear Binding Energy (Bond Energy). This quantity is a measure of bond strength since the stronger the bond, the Higher (Greater) the amount of energy required to break it.

Answer:

126.7 grams/mole of KCl

Answer:

ΔH = -110.5kJ

Explanation:

It is possible to obtain enthalpy of combustion of a particular reaction by the algebraic sum of similar reactions (Hess's law). Using:

1. C(s) + O₂(g) → CO₂(g) ΔH₁ = -393.5kJ

2. CO(g) + 1/2O₂(g) → CO₂(g) ΔH₂ = -283.0kJ

The sum of 1 -2 gives:

C(s) + O₂(g) + CO₂(g) → CO₂(g) + CO(g) + 1/2O₂(g)

C(s) + 1/2O₂(g) → CO(g) ΔH = -393.5kJ - (-283.0kJ) =

Answer:

The Lewis dot diagram is supposed to have dots on each side. What's incorrect is that there isn't a dot on the bottom, only the left and right side and the top. What's correct about this is that there are 5 outer valence electrons, and they correctly put 5 dots, even though they're in the wrong place.

Explanation:

The given Lewis dot diagram of nitrogen is correct for the number of valence electrons for nitrogen. However, they are not correctly placed because two of them are lone pairs and only these two are shown as paired. Remaining three electrons have to be represented as single electrons.

Lewis dot structure of an element represent its valence electrons shown  as dots around the atom. The lone pair of electrons are shown as paired dots and other electrons as single dots.

For compounds, a Lewis diagram shows the bonded and non bonded electrons between bonded atoms. Nitrogen is 7th element and it contains 7 electrons in which 5 are valence electrons.

Nitrogen contains one lone pair of electrons. They have to be shown as paired dots in the Lewis structure. In the given diagram there are two pairs of electrons which is incorrect. Three electrons have to be shown as single dots.

Answer:

161.69×10²³ molecules

Explanation:

Given data:

Volume of water = 499.8 mL

Density of water = 0.967 g/mL

Number of molecules of water = ?

Solution:

First of all we will calculate the mass of water.

Density = mass/volume

0.967 g/mL = mass/499.8 mL

Mass = 0.967 g/mL × 499.8 mL

Mass = 483.3 g

Number of moles of water:

Number of moles = mass/molar mass

Number of moles =  483.30 g / 18 g/mol

Number of moles = 26.85 mol

1 mole contain 6.022×10²³ molecules

26.85 mol ×6.022×10²³ molecules / 1mol

161.69×10²³ molecules

Answer:

density of water at 4.00c  is 0.967 g/mL. Volume of water=499.8mL

Mass of water=density x volume= 0.967 x 499.8=483.3066g

Number of moles of water molecules in given of water = givenmass/molarmass=483.3066/18=26.85

we know that 1 mole has 6.022 x 1023  molecules of water  

so  the number of water=6.022 x 1023  x 26.85=161.69 x 1023 =1.62 x 1025  molecules of water is its upto 3 significant figure.

Answer:

Ionic bonding is the complete transfer of valence electron(s) between atoms and is a type of chemical bond that generates two oppositely charged ions. By losing those electrons, these metals can achieve noble-gas configuration and satisfy the octet rule. ...

Explanation:

Ionic and covalent bonds can occur in substances that have a repeating lattice structure.

Ionic bonds are formed when an atom donates electron (s) to another atom. Covalent bonds, on the other hand, are formed when two atoms share electrons to complete their octet states.

Ionic compounds are formed from a combination of metal and non-metal atoms. They usually have crystalline lattice structures with high melting points.

Covalent compounds are formed between non-metal atoms. They can also have lattice structures but generally have lower melting points because the forces holding the molecules together are weaker.

Average kinetic energy is the average sum of all kinetic energy of all the molecules of gases. Therefore, the correct option is option B that is  average kinetic energy decreases.

It is a energy which is possess by a moving object. It is very difficult to find the correct value of kinetic energy so we find average kinetic energy. Which is very easy to calculate as compared to calculating kinetic energy. It is not dependent on the type of gases or mass of gases.

Mathematically,

K.E=1/2mv²

Where,

m= mass of particles

v= velocity of particles

Water vapor condenses when it cools. Water undergoes a phase shift, transitioning from the  gas to a liquid. Evaporation is the inverse of condensation. When water vapor begins to cool,  average kinetic energy decreases.

Answer:

V₂ =  1.92 L

Explanation:

Given data:

Initial volume = 0.500 L

Initial pressure =2911 mmHg (2911/760 = 3.83 atm)

Initial temperature = 0 °C (0 +273 = 273 K)

Final temperature = 273 K

Final volume = ?

Final pressure = 1 atm

Solution:

Formula:  

P₁V₁/T₁ = P₂V₂/T₂  

P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

by putting values,

V₂ = P₁V₁ T₂/ T₁ P₂  

V₂ = 3.83 atm × 0.500 L × 273 K / 273 K × 1 atm

V₂ = 522.795 atm .L. K / 273 K.atm

V₂ =  1.92 L

Answer:A complex biological structure with many interacting parts might appear, at first glance, as if it were originally created in its present form with all its interlocking components fully formed and intact. It doesn’t seem possible that they developed step by step via biological evolution. In Darwin’s Black Box, Michael Behe introduces a term that he and other proponents of Intelligent Design use for this concept: irreducible complexity. No part of an irreducibly complex system has any apparent function except in its relation to the other parts.
