Answer:

Normality is the number of gram equivalents of solute divided by the volume in liters.

The molarity is the amount of moles in solute divided by the volume in liters.

Moles are the molar mass times grams if you're curious

I hope this helps and good luck!

Answer:

Molarity and normality describe the numbers (moles) of reactants or products dissolved in one liter of solution. Molarity: M = moles of solute contained in one liter of solution. ... Normality is always a multiple of molarity. It describes the “equivalent” moles of reactants involved in chemical reactions.

Explanation:

Normality is a measure of concentration equal to the gram equivalent weight per litre of solution. Gram equivalent weight is the measure of the reactive capacity of a molecule. The solute's role in the reaction determines the solution's normality. Normality is also known as the equivalent concentration of a solution.

Molar concentration is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of amount of substance per unit volume of solution.

Formula for Molar: M = [tex]\frac{n}{v}[/tex]

Answer:

None. Electrons are not in the nucleus.

Explanation:

We know that an atom consist of electrons, protons and neutrons. Neutrons and protons are present inside the nucleus while electrons are present out side the nucleus. Electron has a negative charge and is written as e⁻. The mass of electron is 9.10938356×10⁻³¹ Kg . While mass of proton and neutron is 1.672623×10⁻²⁷Kg and 1.674929×10⁻²⁷ Kg respectively.

Symbol of proton= P⁺  

Symbol of neutron= n⁰  

The number of electron or number of protons are called atomic number while mass number of an atom is sum of protons and neutrons. The umber of protons and electrons are always equal to make the atom electrically neutral .

The atom having atomic number 16 have 16 electrons and these electrons are present out side the nucleus.

Answer:

[H₃O⁺] = 2.5 × 10⁻¹⁰ M

pH = 9.6

Explanation:

Step 1: Given data

Concentration of OH⁻ in the solution ([OH⁻]): 4.0 × 10⁻⁵ M

Step 2: Calculate the concentration of H₃O⁺ in the solution

Let's consider the self-ionization of water.

2 H₂O(l) ⇄ H₃O⁺(aq) + OH⁻(aq)

The ion-product of water (Kw) is:

Kw = 1.0 × 10⁻¹⁴ = [H₃O⁺] × [OH⁻]

[H₃O⁺] = 1.0 × 10⁻¹⁴/[OH⁻]

[H₃O⁺] = 1.0 × 10⁻¹⁴/4.0 × 10⁻⁵

[H₃O⁺] = 2.5 × 10⁻¹⁰ M

Step 3: Calculate the pH of the solution

We will use the following expression.

pH = -log [H₃O⁺]

pH = -log 2.5 × 10⁻¹⁰

pH = 9.6

Taking into account the definition of pH and pOH, the pH and [H₃O⁺] of the solution is 9.602 and 2.5×10⁻¹⁰ M respectively.

First of all, pH is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.

The pH is defined as the negative base 10 logarithm of the activity of hydrogen ions, that is, the concentration of hydrogen ions or H₃O⁺:

pH= - log [H⁺]= - log [H₃O⁺]

Similarly, pOH is a measure of hydroxyl ions in a solution and is expressed as the logarithm of the concentration of OH⁻ ions, with the sign changed:

pOH= - log [OH⁻]

The following relationship can be established between pH and pOH:

pH + pOH= 14

In this case, you know that [OH⁻]= 4×10⁻⁵ M. For this concentration, the pOH is calculated as:

pOH= - log (4×10⁻⁵ M)

pOH= 4.398

Then, pH can be calculated as:

pH + 4.398= 14

pH= 14 - 4.398

pH= 9.602

So, the [H₃O⁺] is calculated as:

9.602= - log [H₃O⁺]

[H₃O⁺]= 10⁻⁹ ⁶⁰²

[H₃O⁺]= 2.5×10⁻¹⁰ M

Finally, the pH and [H₃O⁺] of the solution is 9.602 and 2.5×10⁻¹⁰ M respectively.

K2CO3 (aq) ---> 2K+ (aq) + CO32- (aq)

Explanation:

Dissociation refers to the ability of an ionic compound to breakdown into its respective ions. An ionic compound is formed by the combination of a positive ion (cation) and a negative ion (anion). When these ionic compound dissolves in water, it dissociates i.e. separates into its constituent ions.

In this question involving potassium carbonate being described as a strong electrolyte, which means that it dissociates completely in water as follows:

K2CO3 (aq) ---> 2K+ (aq) + CO32- (aq)

Answer:

Ag 0 is the reducing agent.

Explanation:

Reducing -> gaining electrons

Oxidizing -> losing electrons

Ag lost electrons (became more positive) since it went from a 0 charge to a +1 charge. Therefore it was oxidized. Ag+ is the oxidized product. Reactants that create an oxidized product are called reducing agents. This would make Ag 0 the reducing agent in this reaction.

Answer: B. It increases quickly

Explanation:

As the bromine gas in a container is heated over a flame, the average kinetic energy increases quickly.

The temperature of gas molecules is the measure of average kinetic energy of the gas molecules.

The increase in temperature increases the heat gained by the gas molecules which in turn increases the average kinetic energy of the individual gas molecules.

Thus, as the bromine gas in a container is heated over a flame, the average kinetic energy increases quickly.

H2SO4(aq)+NaOH(s)----->NA2SO4 + H20

When acid and base reaction takes place, it will form salt formation takes place. I.e., neutralization reaction. H₂SO₄+2NaOH→ Na₂SO₄+ 2H₂O.

A neutralization reaction can be defined as a chemical reaction in which an acid and base quantitatively react together to form a salt and water as products.

H₂SO₄ is an acid and NaOH is a base. Acid react with base to form salt and water. Salt will be neutral charge and net ionic charge is zero.

Neutralization takes place when, complete dissociation takes place. If any partial dissociation, it will form acidic salt or neutral salt.

Thus complete dissociation neutral reaction is

H₂SO₄+2NaOH→ Na₂SO₄+ 2H₂O.

Answer:

a: Li₂O

Explanation:

Ionic compounds are good conductors only in liquid state. They do not conduct electricity in their solid state.

The only ionic compound from the given choices is  Li₂O.

Ionic compound do not conduct electricity in their solid state because their ions are locked and are not free to move about their fixed lattice. In liquid states, they go into solution and they are free to move thereby acting as a good conductor.

NaCl + AgNO3 → AgCl + NaNO3

(NH4)2Cr2O7 → Cr2O3 + 4 H2O + N2

Solution

In this equation, two substances combine to make a single substance. This is a composition reaction.

Two different substances react to make two new substances. This does not fit the definition of either a composition reaction or a decomposition reaction, so it is neither. In fact, you may recognize this as a double-replacement reaction.

A single substance reacts to make multiple substances. This is a decomposition reaction.
