Why do the first three elements float on water?
The first three elements in the periodic table (hydrogen, helium, and lithium) are all relatively light gases or solids with low densities. They have fewer electrons and protons compared to heavier elements, leading to weaker intermolecular forces. This makes them less dense than water, allowing them to float on its surface.
Will an egg float in one third salt water and two thirds water?
Yes, an egg will float in a solution of one-third salt water and two-thirds regular water because the increased density of the saltwater makes the egg less dense in comparison, causing it to float.
What two elements make up molecule of water?
A molecule of water is made up of two elements: hydrogen and oxygen.
Can octanol float on water?
Octanol is less dense than water, so it can float on the surface of water. This is because octanol is an organic compound with a lower density than water, allowing it to remain on top when the two liquids are combined.
What one of these substances is not an element water aluminum hydrogen or iron?
Water is not an element; it is a compound made up of two elements, hydrogen and oxygen. Aluminum, hydrogen, and iron are all elements on the periodic table.
