There are many things that are silicate and there are also many things that aren't not silicate. Ice, on the other hand, isn't silicate. Ice is the solid state of water, which the components would be only hydrogen and oxygen. For something to be referred to as silicate, it has to contain at least oxygen and silicon. Water doesn't even have silicon in it so it will never be a silicate. When water is mixed with silicon, it will not be water anymore. Thus, ice is not silicate.
Magnetism is a non contact force. This is brcause magnetism “acts on an object without being in physical contact with it”
Bronsted-Lowry acid is your answer
The phosphate group contribute the following functional features to the structure of phospholipids:
1. Negative charge to interact with water.
2. Place to attach another small molecule.
The phosphate group is made up of four atoms of oxygen which are attached to one atom of phosphorus. This molecule has a net negative charge of -3. In the phospholipid molecule, the phosphate enhanced the polarity of the phospholipid head by mean of its negative charge which react with water. Phosphate group also provide a point where other small molecules such as alcohol, serine, etc can be attached.
