Answer 1
NaCl have stronger ionic bond compared to NaI.
Answer: Option A
Explanation:
Ionic bond is formed between ions having oppositely charged state. So the opposite charging of the ions will lead to mutual attraction of electrons towards the negative charge. While in covalent bonding, the electrons are shared mutually but in ionic bonding, the electrons will be mostly attracted towards the negative charge.
So the ions having highest electronegativity will be forming stronger ionic bond compared to ions having weak electronegativity. Among NaCl and NaI, chlorine will be more electronegative compared to Iodine (I). So the ionic bond will be stronger in NaCl compared to NaI.

Pls answer Mechanical waves can be __.
Group of answer choices
Transverse only
Longitudinal or Transverse
Longitudinal only
Sound waves only
Answers
Answer: Mechanical waves can be Longitudinal or Transverse.
Explanation: So... a mechanical wave is a kind of wave that is a oscillation of matter. Mechanical waves can also transfer energy. However, while it still can transfer over long distances, the wave is limited. it means that the oscillation material is limited. A mechanical wave can be a transverse wave or a longitudinal wave or a surface wave. but since there is only Longitudinal or Transverse that should be your answer.
A transverse wave, its a wave that particles move up and down.
A Longitudinal wave is a wave that moves back and forth.

How many moles of neon are found in 2.22 x 10^28 rp
Answers
Answer:
0.37× 10⁵ moles of neon
Explanation:
Given data:
Number of atoms of neon = 2.22 × 10²⁸
Number of moles = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
For 2.22 × 10²⁸ atoms:
2.22 × 10²⁸ atoms × 1 mol / 6.022 × 10²³ atoms
0.37× 10⁵ moles of neon

Nonrenewable resources are natural resources that are limited in supply and cannot be replaced as quickly as they are used up. True or false
Answers
Answer:
True.
Explanation:
Renewable would mean that they are limited but it would be hard to run out of. Things that would be able to be replaced in a human lifetime or less. And since non would mean the opposite, it would mean that it can be replaced in more than a human lifetime and would be a lot easier to run out of.

How many moles are in 15.5-g SiO2
Answers
Answer:
0.26 moles
Explanation:
Number of moles = mass/molar mass
Mass of SiO2 = 15.5g
Molar mass of SiO2 = 60.08g/mol
Number of moles = 15.5g/60.08g/mol
=0.257
= 0.26 moles
A beaker has 0.2 M of Na2SO4. What will be the concentration of sodium and sulfate ions? [Na+] = 0.4 M, [SO42-] = 0.2 M
[Na+] = 0.2 M, [SO42-] = 0.2 M
[Na+] = 0.4 M, [SO42-] = 0.4 M
[Na+] = 0.2 M, [SO42-] = 0.4 M
Answers
The concentration of sodium and sulphate ions are [] = 0.4 M, [] = 0.2 M
Explanation:
The molar concentration is defined as the number of moles of a molecule or an ion in 1 liter of a solution.
In the given solution, the concentration of the salt sodium sulphate is 0.2M. So, 0.2 moles of sodium sulphate is present in 1 liter of solution.
Assuming 100% dissociation,
1 molecule of sodium sulphate gives 2 ions of sodium and 1 ion of sulphate.
So 0.2 moles of sodium sulphate will give 0.4 moles of sodium ions and 0.2 moles of sulphate ions.
Which of the following is the final concentration of KCl if 500 ml of 0.25 M KCl is diluted to a final volume of 5 L? 0.025 L
0.0025 L
25 L
2.5 L
Answers
Answer:
0.025 M
Explanation:
Given data:
Initial volume = 500 mL (0.5 L)
Initial molarity = 0.25 M
Final volume = 5L
Final molarity = ?
Solution:
M₁V₁ = M₂V₂
M₁ = Initial molarity
V₁ = Initial volume
M₂ = Final molarity
V₂ = Final volume
Now we will put the values in formula.
M₁V₁ = M₂V₂
0.25 M × 0.5 L = M₂ × 5 L
0.125 M. L= M₂ × 5 L
M₂ = 0.125 M. L / 5L
M₂ = 0.025 M

FAQs
Is NaCl a strong ionic bond? ›
The ionic bond in NaCl is strong because the ions are held together by a large, electrostatic force of attraction. The sodium cation (Na+) has a positive charge, and the chlorine anion (Cl-) has a negative charge. These opposite charges attract each other, forming a strong ionic bond.
Is NaCl the strongest bond? ›According to Fajan's rule, the ionic character increases with the increase in the size of the cation and decrease in the size of anion. Hence CsF has higher ionic character than NaCl and therefore more stronger.
Which has a stronger ionic bond NaCl or AlCl3? ›NaCl is more ionic than AlCl3 because ionic character depends on the size of cations. As here anions are same, more the size of cation, more the ionic character.
Which compound would have a stronger ionic bond? ›A cation with a 2+ charge will make a stronger ionic bond than a cation with a 1+ charge. A larger ion makes a weaker ionic bond because of the greater distance between its electrons and the nucleus of the oppositely charged ion.
Is NaCl a strong compound? ›This is why its chemical formula is NaCl. This compound has a molar mass of 58.443 g/mol. The ionic bonds of a molecule of salt are so strong that it takes extremely high energy to break them.
Is NaCl strong or weak salt? ›Is NaCl a Strong or Weak Acid/Base? NaCl (sodium chloride) is a neutral salt. In the making of NaCl, the strong acid HCl cuts down the effect of the strong base NaOH. It's also true for the other way around, meaning the strong acidic nature of HCl gets neutralized too.
What type of bond is NaCl? ›Ionic bonding between sodium and chlorine atoms.
Which bond is most stronger? ›So, in conclusion the ionic bonds are strongest among ionic, covalent and hydrogen bonds.
Which bond is stronger NaCl or MgCl2? ›Since the MgCl2 solution has higher viscosity and stronger hydraphilicity than the NaCl solution, it is much easier for the MgCl2 solution to stick and crystallize on the surface of the metals under the dry condition, and then become solution on the metal surface under the wet condition.
Which is most ionic NaCl? ›Therefore, Sodium chloride is more ionic compared with Aluminium chloride.
Which is more ionic NaCl or Agcl? ›
Since the sodium is in period 3, and group 1a it is more electronegative than silver is. That means the bond character of Sodium Chloride will be more ionic.
Which is more ionic NaCl or KCl? ›KCl is more ionic than NaCl, because K+ has a bigger size than Na+, therefore K+ has less polariazing power than Na+.
How do you know which compound is more ionic? ›The degree of ionic character of a compound is determined by comparing the electronegativities of the species involved. The greater the difference in electronegativity, the more ionic the compound.
What is an ionic bond are they strong? ›The strength of ionic bonds in a cell is generally weak (about 3 kcal/mole) due to the presence of water, but deep within the core of a protein, where water is often excluded, such bonds can be influential."
What is the strongest force in NaCl? ›Answer and Explanation: The strongest intermolecular force between a sodium chloride unit and water is ion-dipole force. This is because NaCl is an ionic compound and thus composed of positively charged sodium ions and negatively charged chloride ions.
Is NaCl an ionic compound? ›Sodium chloride , commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions.
Why NaCl is an ionic compound? ›Since sodium chloride is formed by the transfer of electrons between the elements, therefore, it is an ionic compound.
What is the ionic strength of NaCl? ›6.1 Definition of ionic strength
For instance, for 1 M NaCl, μ = 1.0 , whilst for 1 M Na2SO4, μ = ( 2 2 × 1.0 + 2 × 1.0 ) / 2 = 6 / 2 = 3.0 (see also van Oss, 1994, 2006, for further examples).
So, No Ionic bonds are not weak. They are the strongest bonds.
Which bond is stronger NaCl or mgcl? ›'The strength of ionic bond in M g C l 2 is greater than in N a C l .
