What are the 4 factors that affect the dissolving of a gas

1 answer:

7 0

Nature of the solute and solvent - The amount of solute that dissolves depends on what type of solute it is. While only 1 gram of lead (II) chloride can be dissolved in 100 grams of water at room temperature, 200 grams of zinc chloride can be dissolved. This means that a greater amount of zinc chloride can be dissolved in the same amount of water than lead II chloride.
Temperature - Increasing the temperature not only increases the amount of solute that will dissolve but also increases the rate at which the solute will dissolve. For gases, the reverse is true. An increase in temperature decreases both solubility and rate of solution.

Pressure - Changes in pressure have practically no effect on solubility. For gaseous solutes, an increase in pressure increases solubility and a decrease in pressure decreases solubility. Example: When the cap on a bottle of soda pop is removed, pressure is released, and the gaseous solute bubbles out of solution. This escape of a gas from solution is called effervescence.

Stirring - Stirring brings fresh portions of the solvent in contact with the solute. Stirring, therefore, allows the solute to dissolve faster.

Hope this helps!! (If not I'm sorry!)

Can someone PLEASE HELP me? <br><br> How can you tell if a bond is Covalent?

g100num [7]

There is a couple different ways to determine if a bond is ionic orcovalent. By definition, an ionicbond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals.

Why don't satellites in orbit fly into space?

Alex787 [66]

This is a question similar to one wrestled with by Newton himself, who didn't understand why the planets didn't fall into each other. The reason satellites don't fly into space is because they are being pulled towards the planet by the planet's gravity.

Noise Pollution: An Invisible Threat to Humans and animals.

soldi70 [24.7K]

Answer:

Explanation:

Noise pollution occurs when we have a house which is more than 65 decibels. The effects of noise pollution include physical effects which can be respiratory agitation, headaches, high blood pressure, etc.

Another effect is the psychological effect such as depression, anxiety, fatigue etc. Stress can also lead to sleep disorders and lack of concentration.

The ways to reduce noise pollution are:

1. Using awareness campaign: People should be told about the harmful effects of noise. This will be vital in reducing noise.

2. Government control: Government can play their role by telling those who doesn't adhere to laid out rules regarding noise to pay a fine. Anyone found wanting should pay a fine.
