Calculate the wavelength of the first line in the lymen series of hydrogen spectrum

Natali [406]

Since the electron is de-exited from 1(st) exited state (i.e n=2) to ground state (i.e n=1) for first line of Lyman series. Since the atomic number of Hydrogen is 1. λ = 4/3⋅912 A. 1/R = 912 A

For the following reaction, 8.70 grams of benzene (C6H6) are allowed to react with 13.7 grams of oxygen gas. benzene (C6H6) (l)

artcher [175]

Answer:

Maximum amount of carbon dioxide that can be formed → 7.52 g

Limiting reactant → O₂

Amount of the excess reagent, after the reaction occurs → 12.9 g

Explanation:

We determine the reaction. This is a combustion:

2C₆H₆ (l) + 15O₂ (g) → 6CO₂(g) + 6H₂O (g)

We need to determine the limting reactant so we convert the mass to moles:

8.70 g. 1mol / 78g = 0.111 moles of benzene

13.7 g . 1mol / 32g = 0.428 moles of oxygen

Ratio is 2:15. 2 moles of benzene react with 15 moles of O₂

Then, 0.111 moles of benzene may react with (0.111 .15) /2 = 0.832 moles of O₂

We have 0.428 moles but we need 0.832 moles for the complete reaction, so there are (0.832 - 0.428) = 0.404 moles remaining. Oxygen is the limiting reactant. We work now, with the reaction:

15 moles of O₂ can produce 6 moles of CO₂

So, 0.428 moles of O₂ may produce (0.428 . 6)/ 15 = 0.171 moles of CO₂

We convert the moles to mass → 0.171 mol . 44g / 1mol = 7.52 g

This is the maximum amount of carbon dioxide that can be formed

We convert the mass of the limiting reactant that remains after the reaction is complete → 0.404 mol . 32g / 1mol = 12.9 g of O₂

Which of these molecules is an important source of ENERGY for most organisms?

Nitella [24]

Answer:

Glucose

Explanation:

Glucose molecule is the primary source of energy for most organisms where processes such as glycolysis starts and cellular respiration follows. Bodies of organisms can get energy from carbohydrates, proteins and fats with carbohydrates being the main component for energy where they are converted to glucose which is a form of sugar that reacts to affect blood sugar levels within an hour or two hours after eating.

The second answer option, table salt (NaCl) is incorrect because sodium added in food is vital for functioning of nerves and muscles. Additionally, it helps in fluid regulation and control of blood pressure/volume in the body.

The third answer , hydrochloric acid is not correct because presence of hydrochloric acid in the body helps in breaking down, digestion and absorption of nutrients.

The correct answer choices are : A and D.

What atomic or hybrid orbitals make up the sigma bond between c2 and c3 in propyne, chcch3 ? (c2 is the second carbon in the str

Anvisha [2.4K]

Answer:

$\boxed{\text{$\sigma$(sp-sp$^{3}$); 180$^{\circ}$}}$

Explanation:

(a) Hybridization of orbitals

See the Lewis structure of propyne in the first diagram below.

C1 is directly bonded to two other atoms (H and C2) so it is sp hybridized.

C2 is directly bonded to two other atoms (C1 and C3) so it is sp hybridized.

C3 is directly bonded to four other atoms (C2 and 3 H) so it is sp³ hybridized.

(b) C2-C3 Sigma Bond

See the atomic and molecular orbitals in the second picture below.

C3 is using its hybrid atomic orbitals to form sigma molecular bonds. The C2-C3 sigma bond is formed by the overlap of the C2 sp atomic orbital with the C3 sp³ atomic orbital to make a σ(sp-sp³) molecular orbital.

C1 and C2 are sp hybridized. Since the angle between sp orbitals is 180°, all atoms directly attached the C1 and C2 must be in a straight line. The C-C-C bond angle is 180°.
