When a lid is placed on a pot of boiling water, water drops form all over the lid's inner surface. The vapors of water that are formed up on boiling escape in to the surroundings when there is no lid on the pot. When the pot is covered with a lid the gaseous water molecules condense on the cooler inner surface of the lid to form liquid water droplets. So, the best statement that describes the change in water vapor molecules as they change to liquid, a phenomenon called condensation, is that the change here is a physical change.
The name of the disaccharide above is sucrose
<h3>What are disaccharides?</h3>
Disaccharides are substances which are composed of two molecules of simple sugars or monosaccharides linked to each other.
Below are some examples of disaccharides:
- Sucrose
- Maltose
- Lactose
- Cellobiose
So therefore, the name of the disaccharide above is sucrose

Non-metal are the elements that can accept electrons,this creates a larger positive charge in the nucleus than the negative charge.
Due to this attraction, electron cloud shrinks or come closer to nucleus as the result of opposite charge and become ion .
Hence, the atomic radius of a non-metal<span> is generally smaller than the </span>ionic radius<span> of the same element.</span>
