The Tyndall effect is used to identify a mixture as a colloid.
Answer:
Two unlike charged ions.
Explanation:
The positive charge on one and the negative on the other helps form the ionic bond.
Ionic bonding is the complete transfer of valence electron(s) between atoms. In these types of bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion..
Ionic bonding is observed because metals have few electrons in their outer-most orbitals. By losing those electrons, these metals can achieve noble gas configuration and satisfy the octet rule.
Hello,
Well,You have to understand pretty much everything,So look,If you know the number of protons or electron then you will know its atomic number,and if you know the number of protons and neutrons then you will know the mass of the element.So yeah,this is basically all you need to know to understand the unified structure of atom to help you better understand an element that was unfamiliar to you!
I truly hope this helps
Here we need to see the differences between a liquid and a gas, and how that affects the volume and effects of pressure on them.
The correct option is:
Gases are more readily compressed than liquids are because there is more space between the particles in a gas than in a liquid.
So we have two syringes, one with air and the other with water.
The student applies the same amount of pressure to both of them, but as water is denser than air, in a given change dV of volume in the syringe, the mass of water is larger than the mass of air.
This means that for the same pressure, we should expect the change in volume to be smaller in the syringe with water.
Why this happens?
Gases are more readily compressed than liquids are because there is more space between the particles in a gas than in a liquid.
This means that for the air is easier to be compressed<em> (the distance between particles is larger, so the same pressure compresses more a gas than a liquid)</em> and exit the syringe than for the water, and this translates to the change in volume per unit of pressure applied, <u>which is larger for gases than liquids.</u>
