A solution of HCl has mc012-1. Jpg = 0. 01 M. What is the pH of this solution? Use mc012-2. Jpg. â€""2 â€""1 1 2.

Answers

Answer 1

Answer:

The pH of a solution depicts the alkalinity or the acidity of the components of the solution and is given as a negative log function of hydrogen ions.

The pH of the solution is:

The pH can be estimated as:

$\rm pH= - log \;H^(+)$

Ionic equation of reaction is written as:

$\rm HCl = H^(+)+ Cl^(-)$

The mole ratio between HCl and $\rm H^(+)$ = 1 : 1

Concentration of $\rm H^(+)$ = 0.01 M

$\begin{aligned}\rm pH & = - \rm log \; 0.01\n\n&= 2 \end{aligned}$

Therefore, 2 is the pH of the solution.

Write the net ionic equation for the following reaction:

AgC2H3O2(aq) + CaCl2(aq) →

Answers

Answer:

2Ag^+(aq) + 2Cl^-(aq) --------> 2AgCl(s)

Explanation:

The net ionic equation reflects the main reaction that occurred in the system. It tells you the most important reaction that took place.

If we first put down the balanced molecular equation for the reaction, we have;

CaCl2(aq) + 2 AgC2H3O2(aq) ---------> 2 AgCl(s) + Ca(C2H3O2)2 (aq)

The net ionic equation is;

2Ag^+(aq) + 2Cl^-(aq) --------> 2AgCl(s)

In what way did alchemists contribute to the development of modern chemistry?a. explained changes to matter in mystical, philosophical, or religious terms
b. created models of the internal structure of atoms
c. used experiments to analyze the relationship between gas pressure and volume
d. developed practical equipment, new procedures, and methods of identifying unknown substances

Answers

The correct answer is d. developed practical equipment, new procedures, and methods of identifying unknown substances

Although they were interested in mysticism, there was no place for it in science and they did not explain it in such manners. They also did not create models and didn't deal with gas pressure and volume. They mostly tried to change chemical properties of one chemical into another.

Which pair below describes isotopes of the same element? A) an atom with 6 protons and 8 neutrons - an atom with 8 protons and 6 neutrons
B) an atom with 6 protons and 6 neutrons - an atom with 6 protons and 7 neutrons
C) an atom with 8 protons and 8 neutrons - an atom with 7 protons and 8 neutrons
D) an atom with 7 protons and 6 neutrons - an atom with 6 protons and 6 neutrons

Answers

Answer: The correct answer is Option B.

Explanation:

Isotope is defined as the chemical specie which belong to the same element but differ in their molecular mass.

The isotopes have same atomic mass but differ in their mass numbers

Atomic number is defined as the number of protons or electrons that are present in a neutral atom.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons

Thus, isotopes of an element has same number of protons but they differ in the number of neutrons.

For Example: Chlorine has 2 isotopes, $_(17)^(35)\textrm{Cl}\text{ and }_(17)^(37)\textrm{Cl}$

In $_(17)^(35)\textrm{Cl}$ isotope:

Number of protons = 17

Number of neutrons = 35 - 17 = 18

In $_(17)^(37)\textrm{Cl}$ isotope:

Number of protons = 17

Number of neutrons = 37 - 17 = 20

Hence, the correct answer is Option B.

B because isotopes have the same number of protons but a different number of neutrons
