. Why a chlorine atom with an atomic number of 17 will be negatively charged when its valance shell gains an electron.

Answers

Explanation:

When chlorine bonds and becomes stable, (had a full outer electron shell), because we know that chlorine has 7 electrons in it’s outer shell, it requires 1 to gain noble gas structure. So, when if bonds with an element and then becomes stable, the gaining of an electron means it becomes a negatively charged ion. (an ion being a charged particle.)

In accordance to Brønsted–Lowry acid–base theory, an acid is a substance that loses an hydrogen ion (H+) or proton in an aqueous solution. This theory further indicated that the substance formed after an acid loses its hydrogen ion is called a CONJUGATE BASE.

In the above equation, HCl is the acid because it loses H+ while the substance formed after the loss of H+, which is Cl- is a conjugate base.

What volume of 0.200 M Na2CO3 (Mm = 106 g/mol) solution contains 53.0 g of Na2CO3?

Question 1 options:

0.200 L of solution


0.400 L of solution


0.500 L of solution


1.60 L of solution


2.50 L of solution

Answers

Answer:

volume in Liter = 2.50 L

Explanation:

Given:

Na2CO3 = 0.2 M

Molar mass of Na2CO3 = 106 g/mol

Mass of Na2CO3 solution = 53 gram

Find:

Volume of Na2CO3

Computation:

Number of mol of Na2CO3  = (53 g) / (1.06 x 10² g/mol)

Number of mol of Na2CO3  = 0.5 mol

M = Number of mol / volume in Liter

0.2 = 0.5/ volume in Liter

volume in Liter = 0.5 / 0.2

volume in Liter = 2.50 L

The concentration of hydronium ions is greater than 1 × 10–7 for acidic solutions. True False

Answers

The concentration of hydronium ions (H₃O⁺) is generally greater than 1 × 10⁻⁷ for all acidic solutions: True.

What is an acidic solution?

An acidic solution can be defined as a type of aqeous solution that has a high concentration of hydrogen ions (H⁺), which is typically greater than that of pure water.

As a result of the fact that an acidic solution has a power of hydrogen ions (pH) below 7, the concentration of hydronium ions (H₃O⁺) derived from the protonation of water would be greater than 1 × 10⁻⁷ for all acidic solutions.

In conclusion, we can deduce that a property of all acidic solution is a concentration of hydronium ions (H₃O⁺) that is greater than 1 × 10⁻⁷.

calculate the volume in L od 2.11mol/L CuSo4(aq) solution that contains 0.41 mol copper(2) sulfate

Answers

Answer:

0.194L

Explanation:

Molarity of a solution is its molar concentration, and can be calculated using the formula:

Molarity = no. of moles (n) ÷ volume (V)

According to this question, the molar concentration/molarity of a solution of copper sulfate (CuSO4) is 2.11mol/L and contains 0.41 mol CuSO4. The volume can be calculated as follows;

Volume = no. of moles ÷ molarity

Volume = 0.41mol ÷ 2.11mol/L

V = 0.194 liter

1.37 gram of cupric oxide on reduction with hydrogen gas gives 1.098gram of copper and in next experiment 1.17 gram of copper produce 1.476gram of copper oxide illustrate this satisfy law of definite proportion

Answers

Answer: This satisfies the law of definite proportion or constant proportion and it can be proven below.

Explanation:

The law of constant or definite proportion states that all pure samples of the same compound no matter how they are made; are made up of the same elements combined in the same proportion by mass. The can be verified by finding the ratio of copper to oxygen in the both experiment listed above.

In the first experiment:

1.37 g of cupric oxide contains 1.098 g copper therefore oxygen = 1.37 − 1.098

=0.272 g

The ratio of copper to oxygen is=

1.098 ÷ 0.272

= 4:1

In the SECOND or next experiment:

1.476 g of cupric oxide contains 1.17 g copper Therefore oxygen = 1.476−1.17

=0.306g

The ratio of copper to oxygen is =

=1.176 ÷ 0.306

=3.8:1

Which is approximately≃4:1.

In conclusion, despite the different methods of the experiments, composition of copper of copper in the two different samples are the same and the cupric oxide obtained from different sources contain the same elements ( copper and oxygen) combined in the SAME ratio.

Calculate the mass percent of carbon,oxygen, nitrogen and hydrogen in acetamide, C2H5NO.
Molar Mass:
O=16, N=14,C=12, H =1.

Answers

Answer:

40.68 % C

23.73 % N

8.47% H

27.12% O

Explanation:

The mass percent of an element X in a compound is calculated as the molar mass (MM) of X multiplied by the number of atoms of X in the compound, divided into the molecular weight (MW) of the compound, as follows:

mass percent of X = (MM(X) x number of atoms of X)/MW compound x 100

Thus, we first calculate the MW of acetamide (C₂H₅NO) by using the molar mass of the chemical elements C, H, N and O:

MW(C₂H₅NO) = (12 g/mol C x 2) + (1 g/mol H x 5) + 14 g/mol N + 16 g/mol O = 59 g/mol

Now, we can calculate the mass percent of each element (C, H, N, O) in C₂H₅NO:

Mass percent of C (2 atoms of C in 1 molecule of C₂H₅NO):

          % mass C = (12 g/mol x 2)/(59 g/mol) x 100 = 40.68 %

Mass percent of N (1 atom of N in 1 molecule of C₂H₅NO):

       % mass N = (14 g/mol x 1)/(59 g/mol) x 100 = 23.73 %

Mass percent of H (5 atoms of H in 1 molecule of C₂H₅NO):

       % mass H = (1 g/mol x 5)/(59 g/mol) x 100 = 8.47 %

Mass percent of O (1 atom of O in 1 molecule of C₂H₅NO):

       % mass O = (16 g/mol x 1)/(59 g/mol) x 100 = 27.12 %

The sum of the mass percents has to be equal to 100%:

40.68 % C + 23.73 % N + 8.47% H + 27.12% O = 100%

Answers

Respuesta:

NaF: Enlace iónico

SO₂: Enlace covalente polar

I₂: Enlace covalente apolar

Explicación:

El tipo de enlace entre 2 elementos depende de la diferencia de electronegatividad.

Si ΔEN = 0, el enlace es covalente apolar.Si 0 < ΔEN ≤ 1.7 , el enlace es covalente polar.Si ΔEN > 1.7 , el enlace es covalente iónico.

NaF

ΔEN = |EN(Na)-EN(F)| = |0.9-4.0| = 3.1

El enlace es iónico.

SO₂

ΔEN = |EN(S)-EN(O)| = |2.6-3.5| = 0.9

El enlace es covalente polar.

I₂

ΔEN = |EN(I)-EN(I)| = |2.7-2.7| = 0

El enlace es covalente apolar.
