Lemur [1.5K]

Explanation:

Common ion effect is defined as the effect which occurs on equilibrium when a common ion (an ion which is already present in the solution) is added to a solution. This effect generally decreases the solubility of a solute.

Equilibrium reaction of strontium sulfate and sodium sulfate follows the equation:

$RbClO(s)\rightarrow Rb^{+}(aq.)+ClO^{-}(aq.)$

$HClO(aq)+H_2O\rightleftharpoons H_3O^+(aq.)+ClO^{-}(aq.)$

According to Le-Chateliers principle: If there is any change in the variables of the reaction, the equilibrium will shift in the direction in order to minimize the effect.

In the equilibrium reactions, hypochlorite ion is getting increased on the product side, so the equilibrium will shift in the direction to minimize this effect, which is in the direction of hydrogen hypochlorite.

Thus, the addition hypochlorite ions will shift the equilibrium in the left direction.

The dissociation of hydrogen hypochlorite is suppressed due to the common ion effect.

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!!!

The oxidation number of all the element in free state is 0

Art [367]

Answer:

Zero-Nine

Explanation:

this is becasue these numbers are rather small and if you plug these numbers into an equation you will most likely get 0.

What is the formula for lead carbonate?

Irina18 [472]

Answer: PbCO

Explanation: its quite simple really, you need to get a periodic table and find the symbol of said elements. Lead is Pb, and carbonate is another word for carbon and oxygen, so it is C and O

Select the fastest way to differentiate between the organic and aqueous layers of an extraction.a. Hold a white piece of paper b

valentinak56 [21]

Answer:

b. Add a few drops of one of the layers to a test tube containing 1 mL of water. Shake the test tube to determine the solubility of the layer in water

Explanation:

Option a is not true, it depends on the compound being extracted.

Option c is not true, although most of the solvents used in extractions have lower boiling point than water there are exceptions, for example toluene.

Option d is not true. Again most of the solvents used in extractions are less dense than water, there are many exceptions, for example chloroform, so for equal volumes the chloroform layer will weigh more.

Option b. is the correct one.

One will test the miscibility of the layer in water. If it inmiscible then one would know is the organic layer. If it is the aqueous layer then it will completely be miscible.
