Answer:

See attached picture.

Explanation:

Hello,

In this case, Lewis' structures are basic illustrations of the outer valence shell electrons of a particular molecule. It is employed to understand how the electrons are assembled around the atom. Electrons are represented as "dots" and bonds as lines connecting the two atoms through the aforesaid dots.

In such a way, since carbon has four valance electrons it needs four bonds to accomplish the octet and hydrogen one, the Lewis' dot structure for benzene is shown on the attached picture.

Best regards.

A sample of H2 gas (2.0 L) at 3.5 atm was combined with 1.5 L of N2 gas at 2.6 atm pressure at a constant temperature of 25 °C i
Tamiku [17]
For this system, we use Dalton's law of partial pressures where the total pressure of a gas mixture is said to be equal to the sum of the partial pressures of the gases. The partial pressure of each gas would be calculated by the product of the mole fraction and the original pressure of the gas. We do as follows:

Total pressure = x1P1 + x2P2
Total pressure = (2.0 / 7.0 )(3.5) + (1.5/7.0)(2.6)
Total pressure = 1.56 atm

2Pb(s) + O2(aq) + 4H+(aq) → 2H2O(l) + 2Pb2+(aq)
defon

Answer:

The answer to your question is 0.269 g of Pb

Explanation:

Data

Lead solution = 0.000013 M

Volume = 100 L

mass = 0.269 g

atomic mass Pb = 207.2 g

Chemical reaction

                        2Pb(s) + O₂(aq) + 4H⁺(aq) → 2H₂O(l) + 2Pb₂⁺(aq)

Process

1.- Calculate the mass of Pb in solution

Formula

Molarity = \frac{number of moles}{volume}

Solve for number of moles

Number of moles = Volume x Molarity

Substitution

Number of moles = 100 x 0.000013

Number of moles = 0.0013

2.- Calculate the mass of Pb formed.

                       207.2 g of Pb ----------------- 1 mol

                             x g             ----------------- 0.0013 moles

                        x = (0.0013 x 207.2) / 1

                        x = 0.269 g of Pb

What is the number of elements for 2C3H5O2
ch4aika [34]

Answer: Total Number of Atoms is Nine.

We have 3 atoms of (C)carbon, 5 atoms of (H)hydrogen and 2 atoms of (O)oxygen. So total is 3+5+2=10

It means there are 10 atoms in the compound and from the formula we come to know that there are 2 molecules . Therefore 2×10=20 atoms.

C3 means there are 3 atoms of carbon in one molecule

3C means just 3 atoms of carbon

3C3 means there are 3 molecules of carbon with 3 carbon atoms in each molecule. So total atoms is 9.

Hope I helped!

citric acid has an acid dissociation constant of 8.4 x 10^-4 it would be most effective for preparation of a buffer with a pH of
Sloan [31]

Answer:

(B) 3

Explanation:

Citric acid has an acid dissociation constant (Ka) of 8.4 × 10⁻⁴. When it forms a buffer with its conjugate base (citrate), we can calculate the pH using the Henderson-Hasselbalch's equation.

pH=pKa+log\frac{[base]}{[acid]}

The optimum range of pH is pKa ± 1. The pKa is -log Ka = -log (8.4 × 10⁻⁴) = 3.1. The buffer would be more effective for pH between 2.1 and 4.1, especially around 3.1. So the best choice is (B) 3.
