The deepest trench in the world is 11,000 m in depth. Assuming sea water to have a constant density of 1050 kg/m, determine the
Vanyuwa [196]

Answer:

113406825 N/m²

Explanation:

The pressure at depth of 11,000 m can be calculated by:

Pressure = Atmospheric pressure + Pressure  due to height

Atmospheric pressure = 101325 N/m²

Also,  

P_{height}=\rho\times g\times h

Where,  

\rho is the density of water (\rho=1050\ kg/m^3)

g is the gravitational acceleration = 9.81 m/s²

h = 11,000 m

P_{height}=1050\ kg/m^3\times 9.81\ m/s^2\times 11000\ m

Pressure  due to height = 113305500 N/m²

<u>Pressure = Atmospheric pressure + Pressure  due to height = 101325 N/m² + 113305500 N/m² = 113406825 N/m²</u>

What is an important component of atp that is needed to transfer and release energy directly?
Debora [2.8K]
Answer is: <span>b.phosphate.
</span>ATP is short for adenosine triphosphate
Adenosine triphosphate converts to either the adenosine diphosphate (ADP) or adenosine monophosphate (AMP), in this process energy is<span> released. 
ATP </span>is made of three components: the triphosphate, the sugar ribose and a nitrogenous base (adenine).

yarga [219]

Answer:

The structure of the major organic product isolated from the reaction of 1-hexyne with hydrogen chloride (2 mol) is attached below.

Explanation:

Hydracids are added to triple bonds by a mechanism similar to that of the addition to double bonds. The regioselectivity of the addition of H-X to the triple bond follows the rule of Markovnikov, where the Z conformation predominates in the addition of halide to the alkyne, because in the formation of the carbocation it prefers to place the positive charge on the more substituted carbon where the nucleophilic attack of the halide ion will occur.

With respect to the halogenation of the alkene, the same procedure occurs at the time of the formation of the carbocation, joining the nucleophilic ion to the most substituted carbon.
