How does a certain frequency of line occur in the hydrogen spectrum?

Answer:

C3H2O1

Explanation:

The following data were obtained from the question:

Mass of compound = 0.144 g

Mass of CO2 = 0.352 g

Mass of H2O = 0.0480 g

Empirical formula of compound =?

Next, we shall determine the mass of carbon (C), hydrogen (H) and oxygen (O) present in the compound. This can be obtained as follow:

For carbon (C):

Molar mass of CO2 = 12 + (2×16)

Molar mass of CO2 = 44 g/mol

Mass of CO2 = 0.352 g

Mass of C in the compound

= 12/44 × 0.352

= 0.096 g

For Hydrogen (H):

Molar mass of H2O = (2×1) + 16

Molar mass of H2O = 18 g/mol

Mass of H2O = 0.0480 g

Mass of H in the compound

= 2/18 × 0.0480

= 0.0053 g

For oxygen (O):

Mass of O = mass of compound – (mass of C + mass of H)

Mass of compound = 0.144 g

Mass of C = 0.096 g

Mass of H = 0.0053 g

Mass of O = 0.144 – (0.096 + 0.0053)

Mass of O = 0.144 – 0.1013

Mass of O = 0.0427 g

Finally, we shall determine the empirical formula of the compound as follow:

C = 0.096 g

H = 0.0053 g

O = 0.0427 g

Divide both side by their molar mass

C = 0.096 / 12 = 0.008

H = 0.0053 / 1 = 0.0053

O = 0.0427 / 16 = 0.0027

Divide by the smallest

C = 0.008 / 0.0027 = 3

H = 0.0053 / 0.0027 = 2

O = 0.0027 / 0.0027 = 1

Therefore, the empirical formula of the compound is C3H2O1

Answer:

The current location of the North Magnetic Pole is in the Arctic Ocean, near the coast of northern Canada, specifically in the region of northern Quebec and Ellesmere Island in the Canadian Arctic Archipelago.

Explanation:

However, it's important to note that the North Magnetic Pole is not a fixed point on the Earth's surface, but it is instead constantly moving. The North Magnetic Pole is moving away from Canada and towards Siberia at a rate of about 55 km (34 miles) per year. This movement is caused by changes in the Earth's magnetic field and is known as the "wandering" of the magnetic poles. The exact location of the North Magnetic Pole can be determined by regular measurements and it is used as a reference point for navigation.

Answer:

Because it only needs one more electron to get to a full valence shell (8), so it really wants it and is pulling other electrons in. It also has to do with needing one more electron to fill the 2p shell. It is a small element which means its electrons are pulled tightly to the nucleus.

Answer:

You can infert that it has a mass of 40 grams.It also has desnity of 40 grams per millilieter.

Explanation:

The volume of water raised from the glass is equal to the density of the object which displaces water. Hence, 40 g/ml is the density of the rock.

The Greek mathematician and inventor Archimedes discovered the physical law of buoyancy, which states that any body completely or partially submerged in a fluid (gas or liquid) at rest is subject to an upward, or buoyant, force whose magnitude is equal to the weight of the fluid displaced by the body.

The volume of fluid that has been displaced is equal to the volume of an object that is completely submerged in the liquid or to the portion of the volume below the surface for an object that is only partially submerged.

Therefore, the density of the rock is equivalent to the volume of water level raised in the glass. Thus density of rock is 40 g/ml.

Explanation:

Therefore, the process of beta-oxidation for palmitate involves seven cycles, resulting in the production of eight acetyl-CoA molecules.

A 16-carbon saturated fatty acid with the name palmitate is also referred to as palmitic acid. Fatty acids are converted during beta-oxidation into acetyl-CoA molecules, which can subsequently be used to produce energy in the Krebs cycle or citric acid cycle.

Palmitate is subjected to a number of beta-oxidation processes. Two carbon atoms are removed during each beta-oxidation cycle in the form of acetyl-CoA. Due to the 16 carbon atoms in palmitate, eight cycles of beta-oxidation will be necessary to totally degrade it.

Each beta-oxidation cycle includes the following steps:

Two hydrogen atoms carried by the flavin adenine dinucleotide (FAD) are removed from the fatty acid, oxidising it and creating FADH2.

Trans-2-enoyl-CoA is produced when the double bond between the fatty acid's carbons and forms.

In order to create L-3-hydroxyacyl-CoA, water is added to the trans-2-enoyl-CoA molecule.

By removing two hydrogen atoms from the L-3-hydroxyacyl-CoA, NAD+ (nicotinamide adenine dinucleotide) is able to produce NADH and a molecule of -ketoacyl-CoA.

The -ketoacyl-CoA is then broken down by coenzyme A (CoA) into acetyl-CoA and a shorter acyl-CoA molecule with two less carbon atoms in a process known as thiolysis.

Each pair of two-carbon segments undergoes this procedure once more, and so on, until all 16 carbon atoms in palmitate are reduced to eight acetyl-CoA molecules.

It takes 24 years for 16.0 ng of tritium to decay to the point where 2.0 ng remains.

Tritium has a half-life of 12 years, which means that in each 12-year period, half of the tritium atoms will decay. To calculate the time it takes for a specific amount of tritium to decay, we can use the concept of half-life.

Step 1:

In the first 12 years, half of the tritium will decay, leaving 8.0 ng remaining (16.0 ng / 2).

Step 2:

In the next 12 years (the second half-life), half of the remaining tritium will decay again, leaving 4.0 ng (8.0 ng / 2).

Step 3:

Continuing this pattern, after another 12 years (the third half-life), we have 2.0 ng remaining (4.0 ng / 2).

Therefore, it takes 24 years for 16.0 ng of tritium to decay to the point where 2.0 ng remains.

Answer:

Hydrochloric Acid

Explanation:

NaOH + HCl = NaCl +H2O

In a Neutralization reaction a base (NaOH) and an acid (HCl) react together to form neutral products. H2O is always a product and a salt is also produced such as KCl or in this case NaCl.

The Na switches with the H to form NaCl.

and the 2 H and the O create H2O.

The neutralization reaction for this is Sodium Hydroxide + Hydrochloric acid → Sodium Chloride + Water.

Neutralization is a type of chemical reaction in which an acid and a base react with each other. In this reaction, neutralization results in the formation of any type of salt and water.

The proton (\(H^+\)) from the acid combines with the hydroxide (\(OH^-\)) from the base to make water \((H_2O)\). This type of reaction is known as neutralization reaction because it neutralizes the acid and base. If a strong acid and strong base react completely, then the resulting solution will have a pH of 7 (neutral).

For above given example,

Sodium Hydroxide is reacted with Hydrochloric acid to form Sodium Chloride and Water.

Thus, the neutralization reaction for this is Sodium Hydroxide + Hydrochloric acid → Sodium Chloride + Water.

The electron-domain geometry and molecular geometry of the nitrite ion are trigonal planar and bent, respectively. This is due to the arrangement of the three electron domains around the central nitrogen atom.

The electron-domain geometry of the nitrite ion is trigonal planar. This means that the three electron domains (two lone pairs and one bonding pair) are arranged in a flat, triangular shape around the central nitrogen atom. However, the molecular geometry of the nitrite ion is bent, as the lone pairs on the nitrogen atom cause the two oxygen atoms to be pushed down slightly, resulting in a V-shaped molecule.
It is important to note that the T-shaped and trigonal pyramidal geometries are not possible for the nitrite ion due to the arrangement of the electron domains. The trigonal bipyramidal geometry would also not be applicable, as it would require five electron domains, rather than the three present in the nitrite ion.
