When you accidentally overfill a water glass, the water takes on a dome-like or convex shape, but a half-filled water glass takes on a concave shape, in which the water is higher at the sides of the glass. This is because:Within the glass, adhesive forces dominate, and on top of the glass, cohesive forces dominate. Within the glass, water tries to maximize its surface area, and on top of the glass, water tries to minimize its surface area. Water's surface tension is greater inside the glass than on top of the glass. Adhesive forces between water and the glass get weaker with height.

Suppose that geneticists developed a strain of bacteria that breaks down polyethylene, an otherwise non biodegradable plastic. How would such bacteria be useful? Do you foresee any dangers from these new bacteria?

Answers

Polyethylene is a widely used substance for manufacturing plastic. A bacteria like that could "eat" plastic garbage made from polyethelene which would be really helpful. The danger is that a bacteria can't differentiate between junk and useful things made out of PE, so they would eat everything made from it.

What is double replacement reaction?

A double-displacement reaction has the general formula AB + CD = AD + BC. Double-displacement reactions include the following examples: Ammonium Chloride, a salt, and sodium hydroxide, a base, combine to produce sodium chloride, hydrochloric acid, and water. In a double replacement process, the atoms of two compounds are switched, creating two new molecules.
Metals always replace metals, and nonmetals always replace nonmetals in single replacement processes.
Precipitates are frequently created by double replacement reactions when insoluble chemicals are created.
Checking to see if the cations exchanged anions with one another is the simplest technique to determine whether a reaction is a double displacement.
If the states of matter are mentioned, another indicator to look for is the production of a single solid product and watery reactants (since the reaction typically generates a precipitate)

Which of the following explains the importance of the activation energy acting as a barrier for reactants?

Answers

The energy needed for a chemical reaction is called the activation energy. This energy is to be present in order for the reaction to happen. This can be achieved by supplying or releasing heat from a system of reactants. This can achieved faster by using a catalyst.

What does it mean when water is supercooled?

Even though water is a liquid, some insects are able to stand on its surface due to water's high surface tension. Unbalanced forces pull the water molecules inward which causes the surface of the liquid to have properties similar to that of a stretched elastic membrane. What is responsible for the unbalanced forces in water?A. ionic bonds B. a neutral pH C. hydrogen bonds
