<h3>Sodium chloride  and Sodium bicarbonate are ionic substances</h3><h3>Further explanation </h3>

Atoms have different stability. Unstable atomic atoms will try to form stable electron configurations like those of noble gases. Where noble gases have the number of outer electrons 2 or 8

The formation of electron configurations such as noble gases can be done by sharing electrons with covalent bonds or hand over electrons with ionic bonds

Generally, ionic bonds occur in metals and nonmetallic elements.

While covalent bonds occur because of the use of shared electrons. In general, this bond occurs between nonmetallic elements, which has the same electron attraction

Characteristics of ionic compounds include: solid / crystalline form, soluble in water, conduct electricity

Let see the answer choices

  • Oil

It is a covalent compound because part of the hydrocarbon,  a liquid that forms a bond between elements C, H and O, and does not dissolve in water (floats on water)

  • Cornstarch

Obtained from corn which contains glucose which is a carbohydrate. It does not dissolve in water. Contains a bond between C, H and O. Includes covalent compounds

  • Sodium chloride
  • Sodium bicarbonate

Both are ionic compounds, soluble in water, in solid form

NaCl ⇒ Na⁺ + Cl⁻

NaHCO₃⇒ Na⁺ + HCO₃⁻

Answer:

In this case the answers are

sodium bicarbonate

Sodium chloride

Explanation:

Hello!

Let's solve this!

Ionic substances are substances that are soluble in water. In solution they are separated into positive inodes (cations) and negative inoes (anions).

In this case the answers are

sodium bicarbonate

NaHCO3 ---> Na + + HCO3-

sodium chloride

NaCl ---> Na + + Cl-

Which of the following is a single replacement reaction?
IrinaK [193]

Answer:

Fe + 3NaBr    →   FeBr₃ + 3Na

Explanation:

Single replacement:

It is the reaction in which one elements replace the other element in compound.

AB + C → AC + B

Chemical equation:

Fe + 3NaBr    →   FeBr₃ + 3Na

This chemical equation shows the single replacement reaction. Iron replace the sodium and react with bromine.

All other options are incorrect because,

Ca(OH)₂ + H₂SO₄      →     CaSO₄  + 2H₂O

It is double replacement reaction.

CH₄ + 2O₂     →     CO₂  + 2H₂O

This reaction equation shows combustion.

H₂O + CO₂  →    H₂CO₃

This is synthesis reaction.

t physiological pH, the carboxylic acid group of an amino acid will be ________, while the amino group will be ________, yieldin
astraxan [27]

Answer:

At physiological pH,the carboxylic acid group of an amino acid will be deprotonated while the amino group will be protonated,yielding the zwitter ion form.

Explanation:

Deprotonated means removal of protons in an acid base reaction and protonated means addition of protons in an acid base reaction.

Both protonated and de protonated reaction takes place in catalytic acid bade reaction by changing either it's mass or it's charge.

During formation of zwitter ion, the carboxylic acid will be deprotonated by donating the H+ ion while the amino acid is protonated by taking the H+ ion.

What is the difference between energy levels, sub levels, and orbitals?
Lorico [155]

Explanation:

Orbitals are spaces that have a high probability of containing an electron. ... The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max.
