Calculate the standard molar enthalpy for the complete combustion of liquid ethanol (C2H5OH) using the standard enthalpies of fo
PSYCHO15rus [73]

Answer:

Explanation:

For the reaction

C2H5OH (l) + 3 O2(g) = 2CO2(g) + 3 H2O

We can calculate the  standard molar enthalpy of combustion using the standard enthalpies of formation of the species involved in the reaction according to Hess law:

ΔHºc =  2ΔHºf CO2 (g) + 3ΔHºfH2O(l)  - ( ΔHºf C2H5OH (l) - 3ΔHºfO2 (g) )

( we were not give the water state but we know we are at standard conditions so it is in its liquid state )

The ΔHºfs can be found in appropiate reference or texts.

ΔHºc =  2ΔHºf CO2 (g)+ 3ΔHºfH2O(l)  - (  ΔHºf C2H5OH (l) -+3ΔHºfO2 (g) )

= [ 2 ( -393.52 ) + 3 ( -285.83 ) ] - [(  -276.2 + 0 ) ] kJ

ΔHºc =  -1368.33 kJ

Increased use of incineration is sometimes advocated as a safe way to dispose of chemical waste. But opponents of incineration p
pochemuha

Answer:

Option A is correct.

At the two incinerators at which leaks were reported, staff had had only cursory training on the proper procedures for incinerating chemical waste.

Explanation:

The main aim of the argument presented is to talk down the use of burning by incinerators method to dispose chemical waste. The argument presents great points in that there were 40 incidents at two existing commissioned incinerators in the last year where unexpected releases of dangerous chemical agents happened.

So, basically, the argument is all about how the high frequency of the unsuspected release of dangerous chemical agents should discourage this method of chemical waste disposal.

The argument then concluded that if more chemical waste are disposed using the burning by incinerator method, there will be more unsuspected release of dangerous chemicals.

We are then required to find the statement that most weakens the conclusion that there will be more toxic releases if more chemical waste are burned.

Analysing the Statements one by one

Statement A

This statement provides a possible reason for this high frequency of dangerous chemical releases. It states that the staff haven't been properly trained. So, this means that properly training the staff should most likely lead to lesser cases of toxic releases into the environment.

This is the statement that most weakens the conclusion.

Statement B

The conclusion wasn't about the incinerator method being the safest method. It was about whether increased incineration would lead to more toxic relaeses. So, this doesn't affect the conclusion.

Statement C

This statement says that incineration can be increased without building new incinerators by tapping into unused capacity at the old incinerators. Also doesn't affect rhe conclusion whether increased use of incineration will lead to more toxic leaks.

Statement D

This statement strengthens the argument; which is the opposite of what we're aiming to achieve.

Statement E

This statement hints that the toxic leaks do not have that much of a harmful effect because the toxic releases do not go beyond the property of the incinerator. This also doesnt tackle the conclusion about the frequency of leaks, it only addresses how not harmful the toxic leaks can be.

Hope this Helps!!!

A sample of air is composed of nitrogen, oxygen, and argon gases. if the partial pressure of nitrogen is 587 mm hg, oxygen is 15
oksian1 [2.3K]
The total  pressure  is calculated as below

Total  pressure = partial pressure of (nitrogen +oxygen + argon gas)

= 587 mm hg + 158 mm hg + 7 mm hg = 752  mmhg  is the  total pressure
