Answers
Answer:
Kudzu kills trees and other plants by smothering and choking them with its fast-growing vines, and as the heavy vines engulf trees or shrubs their weight can actually break or uproot trees. A kudzu vine can grow as much as a foot per day and sixty feet during a growing season.

If there is less ionization energy does that mean that it is more reactive? Why?
Answers
Answer:
The greater the ionization energy, the more difficult it is to remove an electron. The ionization energy may be an indicator of the reactivity of an element. Elements with a low ionization energy tend to be reducing agents and form cations, which in turn combine with anions to form salts.

A silver ring reacts with compounds containing sulfur in the air to form silver sulfide, a black substance that makes up the tarnish on the surface of silver objects. To remove that tarnish from the ring, students placed it in a pan lined with aluminum foil and added hot water. Baking soda was added to the hot water and stirred. Students made observations about the process. Which observation of this process provides evidence of a chemical reaction? *
A- Hot water heated the aluminum foil
B- The liquid solution changed color
C- The pan was lined with aluminum foil
D- The hot water cooled
Answers
Answer: B
Explaination: The liquid solution changed color means is turned into a different substance with different properties. It is chemical change .
Liquid solution changed color provides an evidence of a chemical reaction as it is accompanied by a chemical change.
What is a chemical change?Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.
There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical changes:
1) inorganic changes
2)organic changes
3) biochemical changes
During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

What other property of water that relies on adhesion?
HINT: It involves defying gravity.
Answers
Answer:
Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules
Explanation:
*Explanation* Adhesion of water
Water likes to stick to itself, but under certain circumstances, it actually prefers to stick to other types of molecules. Adhesion is the attraction of molecules of one kind for molecules of a different kind, and it can be quite strong for water, especially with other molecules bearing positive or negative charges.
For instance, adhesion enables water to “climb” upwards through thin glass tubes (called capillary tubes) placed in a beaker of water. This upward motion against gravity, known as capillary action, depends on the attraction between water molecules and the glass walls of the tube (adhesion), as well as on interactions between water molecules (cohesion).

A toy truck falls off a table. As it falls, the toy truck has potential energy and kinetic energy.
Explain how the toy truck can have potential and kinetic energy at the same time.
Answers
As the toy falls off a table, it can have potential and kinetic energy at the same time because of the height (h) and velocity (v) of the object, respectively.
When the truck falls off a table it has potential energy (P) and kinetic energy (K) given by:
[tex] P = mgh [/tex] (1)
[tex] K = \frac{1}{2}mv^{2} [/tex] (2)
Where:
m: is the mass of the toy
g: is the acceleration due to gravity
h: is the height of the table
v: is the velocity of the toy
Kinetic energy (equation 2) is related to the velocity (v) of the moving toy while it is falling from the table.
Potential energy (equation 1) is due to the gravitational acceleration (g) exerted on the toy when it is at a height (h) above the table. This energy decreases as the object approaches the ground (where "h" is zero).
Therefore, the truck can have potential and kinetic energy at the same time because of the height and velocity of the toy, respectively.
