How is the behavior of food coloring in the pool and heated water different? What caused the difference in their behavior?
Answer )In hot water, the food coloring diffuses (spreads out) through the water quickly. In cold water, the food coloring diffuses (spreads out) through the water slowly. The hot water causes the food coloring to diffuse faster. At higher temperatures, particles move faster.

Ideally speaking, bonds tend to form between two particles such that they are separated by a distance where _______ net force is exerted on them, and their overall energy is _________.
The question is incomplete, the complete question is;
Ideally speaking, bonds tend to form between two particles such that they are separated by a distance where _______ net force is exerted on them, and their overall energy is _________.
A.zero, maximized
B. a negative, minimized
C. a positive, minimized
D. a positive, maximized
E. zero, minimized
F. a negative, maximized
Answer:
E. zero, minimized
Explanation:
Chemical bonding occurs when there is a dynamic equilibrium between the attractive and repulsive forces. This means that the magnitudes of the attractive and repulsive forces are equal and the net force is zero.
Also, at the point where bonding occurs, the energy of the system is minimum. The point on the potential energy curve that represents the bonding energy is the lowest point on the curve.
Ideally speaking, bonds tend to form between two particles such that they
are separated by a distance where zero net force is exerted on them, and
their overall energy is minimized.
For chemical bonding to occur there must be dynamic equilibrium. This is
formed from magnitude of the attractive and repulsive forces being equal
which translates to the net force being zero.
The overall energy at the exact point of bonding is at the minimum which is
to allow easy transfer or sharing of electrons in the formation of a compound.

which is the best definition of a molecule
Answer:
Explanation:
A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge. In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped and molecule is often used when referring to polyatomic ions

Titanium consists of two isotopes of masses 46.90 amu and 48.95 amu. If the first isotope has a percent abundance of 70.84%, what is the percent abundance of the second isotope?
Answer: 29.16%
Explanation:
The total of 2 percentages need to equal 100% so we subtract the percent they gave us from 100.

Answer:
2,3,6,1
2,3,6,1
Explanation:
The unbalanced reaction expression is given as:
AlBr₃ + K₂SO₄ → KBr + Al₂(SO₄)₃
We need to balanced this reaction equation. Our approach is a mathematical method where we assign variable a,b,c and d as the coefficients.
aAlBr₃ + bK₂SO₄ → cKBr + dAl₂(SO₄)₃
Conserving Al; a = 2d
Br: 3a = c
K: 2b = c
S: b = 3d
O: 4b = 12d
Let a = 1, c = 3, d = [tex]\frac{1}{2}[/tex] b = [tex]\frac{3}{2}[/tex]
Multiply through by 2 to give;
a = 2, b = 3, c = 6 and d = 1
2AlBr₃ + 3K₂SO₄ → 6KBr + Al₂(SO₄)₃

The atoms and molecules are matter. Therefore, option A and B are correct.
What is matter ?Matter is defined as anything that occupies space and has mass—in other words, the "stuff" of the universe. All matter is composed of substances known as elements, which have distinct chemical and physical properties and cannot be broken down into other substances via ordinary chemical reactions.
Matter is defined as anything that occupies space and has mass. Water and air are examples of matter, whereas feelings and sound are not.
Physical and chemical properties can be used to classify matter. Matter is defined as something that occupies space and has mass. Solid, liquid, and gaseous are the three states of matter. The conversion of a material from one state of matter to another without changing its chemical composition is referred to as a physical transition.
Thus, option A and B are correct.

An ideal gas system undergoes an isovolumetric process in which 20J of energy is added as heat to the gas. What is the change in the systems internal energy
Answer:
the change in the system internal energy is 20 J
Explanation:
The computation of the change in the system internal energy is as follows:
Since the volume remains constant so the work done would be zero
Now the change in the internal energy is
= Heat given to system - work done
= 20 J - 0
= 20 J
hence, the change in the system internal energy is 20 J
The same is to be considered

Differentiate between acids and bases on the basis of their pH values. Give an example of each type. keep it simple
Answer:
differences
Any compound with a pH value between zero to seven is considered acidic, whereas a pH value between seven to fourteen is a base. An acid is called a proton donor, while a base is called a proton acceptor (Kolb, 1978).
examples are:
baking soda is basic (pH = 9.0).
Orange juice is mildly acidic (pH = approximately 3.5)
The environment in your stomach is highly acidic (pH = 1 to 2).
