How is the behavior of food coloring in the cool and heated water different? What caused the differences in their behavior?
Please don't just give the sample response.
Answer:
The food coloring mixes much faster in the hot water than it mixes with the cold water. This is because in the hot water, water molecules have more energy and are moving faster than the molecules of cold water.

Which statement best describes the motion of
the dye molecules in the water?
The dye molecules
o move in a directed way from high to low
concentration.
o move randomly through collisions in no
particular direction.
stay close to other dye molecules as they
move through the water.
Low
Check ansive
Answer:The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion: diffusion is the movement of molecules of a substance from one position to another.
Explanation:
Option A is correct. The statement that best describes the motion of the dye molecules in the water is "the dye molecules move in a directed way from high to low".
The motion of dye molecules in water is known to be random. Another name for random motion is Brownian motion and since diffusion is also Brownian motion, hence we can term the motion of the dye molecules in the water as "diffusion".
The water is held together by intermolecular forces and these forces are the ones that attract the molecules of the die carrying them away and making the process of molecular transport of the dye to be accelerated (moving from a region of high concentration to low concentration).
In conclusion, the statement best describes the motion of the dye molecules in the water is "the dye molecules move in a directed way from high to low".

Kiley wants to balance the equation H2 + N2 → NH3. Which would be her first step in balancing an equation?
Answer: The balanced equation will be
6H2 + N2 → 2NH3
Explanation:
First step is to balance nitrogen
ie, H2 + N2 → 2NH3
Second step is to balance hydrogen accordingly
ie, 6H2 + N2 → 2NH3
This is the perfect balanced equation.

A girl stands on a bathroom scale. In metric units, the scale indicates that her weight is 42
Newtons. This means the force of gravity is pulling her feet onto the scale with a force of 42
Newtons. With what force does the scale push back up against her feet?
Answer:
The bathroom scale pushes her back 42 metric units, the same as her weight. Newton's 3rd law says that how much ever you push onto some object, it pushes back onto you with that same amount of pressure.

What happens to the reaction rate as the reactants get used up in a reaction?
O
A. The rate of the reaction is not affected by the concentration of
reactants.
B. The rate of the reaction increases steadily as products are formed.
O
O
O
C. The rate of the reaction begins to decrease as reactants are used
up
O
D. The rate of the reaction stays constant until the reactants are
gone.
The rate of the reaction depicts the speed at which the reaction occurs to produce the products. As the reactants get used up the reaction rate starts decreasing. Thus, option C is correct.
What are the factors affecting reaction rate?
The reaction rate of the chemical reaction gets affected by numerous factors that include temperature, the concentration of the reactants, catalyst, surface area, and physical state of the reactant.
The concentration of the reactant has a direct effect on the reaction rate as they are the deciding factor of the product formation. At the beginning of the reaction, the speed is fast compared to the end.
As the reactants start getting used up the reaction rate slows down as the molecules are not able to collide faster with other molecules to form the product.
Therefore, in option C. the reaction rate decreases with a decrease in concentration.

Complete the sentences to identify the difference between a nonmetal atom and its anion.
In an anion, there are more *blank* than *blank*, giving the anion a *blank* charge.
In nonmetal atoms, the number of *blank* and *blank* are the same and there is a *blank* charge.
key bank:
- a positive
- no net
- electrons
- protons
- a negative
- neutrons
Answer:
more protons than neutrons and the number of electrons and blank are blank
Explanation:
The complete sentences that distinguish the difference between a nonmetal atom and its anion are as follows:
In an anion, there are more electrons than protons, giving the anion a negative charge. In nonmetal atoms, the number of protons and neutrons are the same and there is a negative charge. What are Non-metals?Non-metals may be defined as the type of chemical element that lacks the characteristics of a metal. They do not show any metallic attributes. But in the periodic table, they range from colorless gases to shiny and high melting point solids.
In the whole periodic table, elements are classified into three parts. They are metals, non-metals, and metalloids. Each classification has its own attributes and characteristic properties.
The non-metals significantly gain electrons due to their stronger nuclear charge and become negatively charged anions.
Therefore, the complete sentences that distinguish the difference between a nonmetal atom and its anion are appropriately described.
