If, the hull of the submarine breaks and it descends to a depth where the pressure is 150 atm and the temperature is 3°C, the volume of the gas inside the submarine would be approximately 1.054 x 10⁵ L.

To solve this problem, we can use the combined gas law, which relates the initial and final conditions of pressure, volume, and temperature for a given amount of gas. The combined gas law equation is;

(P₁ × V₁) / (T₁) = (P₂ × V₂) / (T₂)

Where; P₁ = Initial pressure

V₁ = Initial volume

T₁ = Initial temperature

P₂ = Final pressure

V₂ = Final volume

T₂ = Final temperature

Given; P₁ = 1.0 atm

V₁ = 1.2 x 10⁵ L

T₁ = 15°C + 273.15 = 288.15 K (convert to Kelvin)

P₂ = 150 atm

T₂ = 3°C + 273.15 = 276.15 K (convert to Kelvin)

Now, let's plug in the values into the equation and solve for V₂;

(1.0 atm × 1.2 x 10⁵ L) / (288.15 K) = (150 atm × V₂) / (276.15 K)

Simplifying the equation;

V₂ = (1.0 atm × 1.2 x 10⁵ L × 276.15 K) / (150 atm × 288.15 K)

V₂ ≈ 1.054 x 10⁵ L

Therefore, the volume of the gas inside the submarine would be approximately 1.054 x 10⁵ L.

Acid catalyzed hydration is a reaction that involves the addition of water to an alkene in the presence of an acid catalyst. The reaction is typically carried out using a strong acid, such as sulfuric acid, which allows the reaction to proceed more quickly and efficiently.

The general reaction is as follows:

R-CH=CH-R + H₂O → R-CH(OH)-CH-R

In this reaction, the alkene undergoes an addition reaction, in which the double bond is broken and two new bonds are formed. One of the new bonds is formed between the alkene and a hydrogen atom from the water molecule, while the other is formed between the alkene and a hydroxyl group from the water molecule.

The acid catalyst plays an important role in this reaction by increasing the electrophilicity of the alkene, which allows it to react more readily with the water molecule. The acid catalyst also helps to stabilize the intermediate species that are formed during the reaction, which helps to drive the reaction forward.

Overall, acid catalyzed hydration is an important reaction in organic chemistry, and is used to produce a variety of different compounds, including alcohols and other functionalized molecules.

It is one of the reactions that leads to the formation of a carbon-carbon bond, the Grignard reaction is an essential component of organic synthesis.

A Grignard reagent or Grignard compound is a substance compound with the overall equation R−Mg−X, where X is a halogen and R is a natural gathering, typically an alkyl or aryl. Phenylmagnesium bromide (C 6H 5)-MgBr and methylmagnesium chloride (CH 3) are two typical examples.

With acidic hydrogen atoms in molecules like alcohols and water, Grignard reagents quickly react. An alkane is produced when a Grignard reagent reacts with water and a proton takes the place of the halogen. As a result, the Grignard reagent offers a two-step procedure for transforming a haloalkane into an alkane.

Alkyl or aryl magnesium bromides, also known as Grignard reagents, are used in the reaction.

Alkyl bromides are created when an alkene and HBr interact in the presence of factors such as heat, sunshine, or peroxides. A radical intermediate is used in this reaction to progress.

What is Alkene?

Alkenes, and ethene in particular, play a crucial role in the chemical industry. They are created during the cracking of the alkanes but are not present in significant amounts in crude oil. Like all hydrocarbons, alkenes burn in the presence of air to produce carbon dioxide and water. Ethene reacts violently in oxygen, making it ineffective as a fuel. Additionally, the alkenes are too useful for the production of plastics and many other compounds to be used as fuels in the chemical industry.

Compound A reacts with HBr to produce 2-bromohexane as a byproduct. 1-Bromohexane is created when component an interacts with HBr and peroxide.

In the absence of light, the carbocation intermediate is used to add HBr. In the presence of light, the radical intermediate is used to add HBr.

The calculation of quantitative relationships in chemical reactions. 3.45 grams of H2 are needed to produce exactly 1.15 moles of NH3.

To solve this problem, we need to use stoichiometry, which is the calculation of quantitative relationships in chemical reactions. The balanced equation tells us that for every 1 mole of NH3 produced, we need 3 moles of H2. So, to produce 1.15 moles of NH3, we will need:
1.15 moles NH3 x (3 moles H2 / 2 moles NH3) = 1.725 moles H2
Now, we can use the molar mass of H2 to convert from moles to grams:
1.725 moles H2 x (2.02 g H2 / 1 mole H2) = 3.48 g H2
Therefore, we need exactly 3.48 grams of H2 to produce 1.15 moles of NH3.
To calculate the grams of H2 needed to produce 1.15 moles of NH3, we can use the stoichiometry of the balanced chemical equation: N2 + 3H2 → 2NH3.
First, we determine the mole ratio of H2 to NH3. According to the equation, 2 moles of NH3 are produced from 3 moles of H2. Therefore, the mole ratio is 3:2 (3 moles of H2 to 2 moles of NH3).
Next, we can set up a proportion to find the moles of H2 needed to produce 1.15 moles of NH3:
(3 moles H2 / 2 moles NH3) = (x moles H2 / 1.15 moles NH3)
To solve for x, cross-multiply:
2 moles NH3 * x moles H2 = 3 moles H2 * 1.15 moles NH3
2x = 3.45 moles H2
Now divide by 2:
x = 1.725 moles H2
We have found that 1.725 moles of H2 are needed to produce 1.15 moles of NH3. Finally, to convert moles of H2 to grams, we multiply by the molar mass of H2 (2 g/mol):
1.725 moles H2 * 2 g/mol = 3.45 g H2
Thus, 3.45 grams of H2 are needed to produce exactly 1.15 moles of NH3.

Answer: 3.It increases when the temperature increases.

Explanation:

The speed of most chemical reactions increase as if the temperature of those same reactions increase as well. This is because a higher temperature allows for reactants to gain the necessary activation energy needed to react.

Enzymes are another reason. Enzymes are catalysts in reactions which reduce the activation energy needed for a reaction to occur and enzymes work best in certain higher temperatures - not too high - so this also leads to the reaction speed increasing due to temperature increases.

The chief hazard of radiation damage to living cells is DNA (deoxyribonucleic acid) mutation.

Radiation can cause damage to living cells, and one of the most significant consequences is DNA mutation. DNA contains the genetic information that guides the functioning and development of cells. When cells are exposed to radiation, ionizing radiation in particular, it can directly interact with the DNA molecule, causing structural damage such as breaks or cross-links in the DNA strands.

These alterations can lead to errors in DNA replication and repair processes, resulting in mutations. Mutations can disrupt the normal functioning of genes, leading to various harmful effects, including the development of cancerous cells or other genetic disorders. Furthermore, mutations can be passed on to subsequent generations, perpetuating the genetic damage caused by radiation exposure.

Therefore, DNA mutation is the primary hazard associated with radiation damage to living cells, emphasizing the importance of protecting against excessive radiation exposure to maintain cellular integrity and genetic stability.
