As the name suggested that defect in mass of any substance given idea about the mass defect and it will be define as the difference between the atomic mass of an atom and sum of the masses of all constitute particles present inside the nucleus.

Mass of daughter nuclei will take in consideration when only nuclear reaction takes place.Missing line of absorption is not related to the mass, else it is related to the concentration.Difference between measured mass and average isotope is not considered in mass defect because it is calculated for the individual atom not for all isotopes of that atom.

If 4.5 moles of nitric acid falls into 8000 L of pure water, what will be the change of the pH of the solution? Show all of your work for full credit. (Note that nitric acid dissociates completely and puts in one hydrogen ion for each molecule of nitric acid).

*due soon*

Answers

Answer:

3.24

Explanation:

It is known that nitric acid is a strong acid, so it will dissociate completely, resulting in [tex]H^+[/tex] and [tex]NO_3^-[/tex] ions being present in solution. We also know that pure water has a neutral pH due to the chemical equilibrium of [tex]H_2O(l)[/tex] ⇄ [tex]H^+(aq) + OH^-(aq)[/tex] signifying equal parts of hydrogen and hydroxide ions.

Now, we must convert from 4.5 moles of nitric acid to moles of hydrogen. This can be accomplished using unit conversions and the chemical dissociation equation [tex]HNO_3(s) - > H^+(aq) + NO_3^-(aq)[/tex]

[tex]4.5molHNO_3 * \frac{1 mol H}{1 mol HNO_3} = 4.5molH+[/tex]

Then, using the pH equation [tex]-log[H+] = pH[/tex] and the formula for molarity [tex]M = \frac{g}{L}[/tex], we can find the value of [tex][H^+][/tex] and in turn the pH of the resulting solution. Keep in mind that both answers for grams of the hydrogen ion and molarity of the hydrogenion should have two significant figures.

[tex]4.5mol H^+ * \frac{1.01gH^+}{1 mol H^+} = 4.6g H^+\\\frac{4.6gH^+}{8000L sol} = 5.8*10^{-4} M H^+[/tex]

Now the pH equation may be used.

[tex]-log(5.8*10^{-4}) = 3.24[/tex]

Note that logarithmic significant figures dictate that the logarithm of a number with x significant figures will result in a value with x digits after the decimal point, meaning that this answer will have two digits after the decimal point and three significant figures.

Answers

During change of phase, the molecules of a substance acquire enough kinetic energy to overcome the forces of attraction between its molecules.

What is change of phase?

Change of phase occurs when a substance acquires enough energy to overcome the forces of attraction between its molecules to transition from one state of matter to another.

During a change of phase, kinetic energy of the molecules of the substance increases due to the application of heat, and the freedom of movement of the molecules increases.

Change of phase can occur as follows;

from solid to liquid and vice versafrom solid to gas and vice versafrom liquid to gas and vice versa

Therefore, during change of phase, the molecules of a substance acquires enough kinetic energy to overcome the forces of attraction between its molecules leading to increased freedom of movement of the molecules.

What is a covalent bond?

A covalent bond is a type of chemical bond in which elements share electrons. It is formed between nonmetals.

Based on the periodic table, which pair of elements would most likely form a covalent bond?

boron (B) and carbon (C). B is a metalloid and C a nonmetal, so they don't form covalent bonds.aluminum (Al) and silicon (Si). Al is a metal and Si a metalloid, so they don't form covalent bonds.carbon (C) and oxygen (O). Both C and O are nonmetals, so they do form covalent bonds.magnesium (Mg) and sulfur (S).

What is the molar mass of NaCl? If you need to add 0.2 moles of NaCl to 500 mL of water, how many grams of NaCl do you need to add?

Answers

Answer:

321 g

Explanation

All you need to know here is that the molarity of a solution tells you the number of moles of solute present in exactly

1 L

of the solution.

In your case, a

2.20-M

sodium chloride solution will contain

2.20

moles of sodium chloride, the solute, for every

1 L

of the solution.

So if every

1 L

of this solution must contain

2.20

moles of sodium chloride in order for the solution to have a molarity of

2.20 M

, it means that

2.50 L

of this solution must contain

2.50

L solution

2.20 moles NaCl

L solution

=

5.50 moles NaCl

To convert the number of moles of sodium chloride to grams, use the molar mass of the compound.
