What environmental effect has cotton harvesting had in asia

1 answer:

7 0

It has used a lot of water to produce the cotton. The cotton also has hurt the environment because of all the chemicals that are applied. If the polluted water gets into the rivers or water ways, you now have a polluted body of water making it not safe.

Determine the number of miles of H in each sample;

Inessa [10]

1) Answer is: there are 9.04 moles of the hydrogen in 4.52 mol of the water.

n(H₂O) = 4.52 mol; amount of the water molecules.

In one molecule of the water, there are two hydrogen atoms.

n(H₂O) : n(H) = 1 : 2.

n(H) = 2 · n(H₂O).

n(H) = 2 · 4.52 mol.

n(H) = 9.04 mol; amount of the hydrogen atoms.

2) Answer is: there are 25.29 moles of the hydrogen in 8.43 mol of the ammonia (NH₃).

n(NH₃) = 8.43 mol; amount of the ammonia molecules.

In one molecule of the ammonia, there are three hydrogen atoms.

n(NH₃) : n(H) = 1 : 3.

n(H) = 3 · n(NH₃).

n(H) = 3 · 8.43 mol.

n(H) = 25.29 mol; amount of the hydrogen atoms.

3) Answer is: there are 0.408 moles of the hydrogen in 0.102 mol of the hydrazine (N₂H₄).

n(N₂H₄) = 0.102 mol; amount of the hydrazine molecules.

In one molecule of the hydrazine, there are four hydrogen atoms.

n(N₂H₄) : n(H) = 1 : 4.

n(H) = 4 · n(N₂H₄).

n(H) = 4 · 0.102 mol.

n(H) = 0.408 mol; amount of the hydrogen atoms.

4) Answer is: there are 770 moles of the hydrogen in 35.0 moles of the decane (C₁₀H₂₂).

n(C₁₀H₂₂) = 35.0 mol; amount of the decane molecules.

In one molecule of the decane, there are twenty two hydrogen atoms.

n(C₁₀H₂₂) : n(H) = 1 : 22.

n(H) = 22 · n(C₁₀H₂₂).

n(H) = 22 · 35.0 mol.

n(H) = 770 mol; amount of the hydrogen atoms.

A stream consisting of 48.9 mole% benzene (B) and 51.1% toluene (T) is fed at a constant rate to a process unit that produces tw

marshall27 [118]

The vapor flowrate will vary with time by ; gradually increasing from zero to one half of the molar feed flow rate and then remain constant ( C )

Although the options related to your question is missing attached below are the missing options

Vapor flow rate is the amount of vapor per unit of time that flows through a specific area at a given time .

Given that the stream consists of 48.9 mole% of benzene and 51.1% toluene fed at a constant rate into a process unit. The vapor flowrate will vary with time because it will gradually increase from zero to 1/2 of the molar feed flow rate before it will remain constant.

Hence we can conclude that The vapor flowrate will vary with time by gradually increasing from zero to one half of the molar feed flow rate and then remain constant.
