What needs to happen for a solute to dissolve in a particular solvent? A. The attractions between the solute and solvent molecul
Masja [62]

The attractions between the solute and solvent molecules must be greater than the attractions keeping the solute together and the attractions keeping the solvent together. This needs to happen for a solute to dissolve in a particular solvent .

Answer: Option A

<u>Explanation:</u>

Solute means the substances which get dissolved by another one, Ex: salt. On the other hand, Solvent refers the substance which dissolves. Ex: Water. To get dissolved in solvent, the particles present in solute move away.

It is possible only when the attractive force between solute and solvent are greater than binding force of solute and solvent.  Separation and mixing up with solvent particles, in general, called as solvatation.

Answer:

POLLUTANT, SOURCE AND IMPACT

Carbon Monoxide

SOURCE:- carbon monoxide main sources are from our homes, eg; wood stoves and fire place, generators, gas stoves, kerosene heaters, leaking chimneys, tobacco smokes etc

IMPACT:- carbon monoxide can cause organ failure as it reduces the amount of oxygen the hemoglobin been carried in the red blood cells to this organs in our body.

Carbon dioxide

SOURCE:- carbon dioxide can be from both human and natural source. Example of the sources includes; natural source ( ocean release, decomposition and respiration), human activities ( burning of coal, oil and natural gas, cement production etc)

IMPACT:- carbon dioxide causes difficulties in breathing as it displaces oxygen in the air.

It also increase the greenhouse effect (global warming) as more heat energy gets trapped by the atmosphere causing the planet to become warmer.

Sulphur dioxide

SOURCE:- sulphur dioxide mainly occur due to human activities such as fossil fuel combustion at industrial facilities, in ships etc.

IMPACT:- Sulphur oxide has been linked to many health effect and diseases such as cardiovascular diseases. It also causes respiratory problems, asphlegm and asthma attacks, irritation of lungs, throat and nose as well.

Nitrogen oxides

SOURCES:- nitrogen oxides also comes from human activities such as; combustion of fossil fuel, making of nitric acid, refining metals as well as petrols, explosive, food manufacturing etc.

IMPACT:- Nitrogen oxides has also been linked to many respiratory health issues such as bronchitis and wheezing. It causes the lining of the lungs to inflame there by reduce the immunity of the lungs to respiratory diseases.

Methane

SOURCE:- methane can be from either natural or human activities. The natural source includes; food digestion by cattles, decay of organic materials. Human activities such as waste management, rice production, oil and gas production etc.

IMPACT:- Methane is considered a green house gas like carbon dioxide, it contributes to the trapping of heat energy in the atmosphere which causes global warming. It is also linked to serious health issues such cardiovascular, respiratory and neurological problems.

Particulates

SOURCE:- particulates are fine tiny particles of matter found in the air, it might be in solid or liquid form. Example; dust, smoke, fumes etc. This particles can suspended in the air for an extended periods of time.

IMPACT:- exposure to particulates can cause variety of respiratory health problems such as difficulties in breathing, coughing, lungs and heart problem etc.

Would mouth to mouth resuscitation between two fish work?
Nady [450]

I don't think it will work.

Fish breathe with gill not lungs. Unlike lungs, gill works one way. You breathe out air out of you mouth but fish dump the water from their gill so they shouldn't be able to push water out of their mouth.

Even if the could fish push the water through their mouth, the gas exchange didn't happen because the water didn't move through the gill. The fish that giving water cannot breathe while giving resuscitation.
