The healing of a cut finger. Is it a physical or chemical change? Explain.
Wound healing is a chemical change.
A chemical change involves the formation of a new substance. A substance changes form from one form into another in the process. A physical change does not involve the formation of new substances. Wound healing involves a number of chemical changes.
A wound can also be referred to as a tissue damage. When a tissue is damaged, bleeding results. Bleeding could lead to so much loss of blood.
The human body has mechanisms in place to combat this excessive loss of blood. This occurs when a complex biochemical pathway leads to the formation of fibrinogen. The enzyme thrombin converts fibrinogen to fibrin. The formation of fibrin is very essential to the wound healing process.
We can see that a series of chemical changes are involved in the process of wound healing when your finger is cut.

Sam is making an aquaponics garden. He needs 2.3 dkg of granite. He has 460 g. How much more does he need? Explain your answer with your work.
Explanation:
He needs 2.3 dkg
dkg is a unit of mass and represents dekagrams.
The relationship between dkg and g is given as;
1 dkg = 10g
This means he needs 2.3 * 10 = 23 g of graphite.
Since he already has 460g of graphite, he doesn't need any additional graphite.

Materials expand when heated. Consider a metal rod of length L0 at temperature T0. If the temperature is changed by an amount ΔT, then the rod’s length changes by ΔL=αL0ΔT, where α is the thermal expansion coefficient.
For steel, α=1.24×10−5∘C−1.(a) A steel rod has length L0=40cm at T0=40∘C. What is its length at T=180∘C?
(Use decimal notation. Give your answer to three decimal places.)
L≈cm
(b) Find its length at T=90∘C if its length at T0=120∘C is 65 in.
(Use decimal notation. Give your answer to three decimal places.)
L≈ in.
(c) Express length L as a function of T and α if L0=60in. at T0=150∘C.
(Use symbolic notation and fractions where needed.) L(T,α)=
Answer:
(a) The length at temperature 180°C is 40.070 cm
(b) The length at temperature 90°C is 64.976 inches
(c) L(T, α) = 60·α·T - 9000·α + 60
Explanation:
(a) The given parameters are
The thermal expansion coefficient, α for steel = 1.24 × 10⁻⁵/°C
The initial length of the steel L₀ = 40 cm
The initial temperature, t₀ = 40°C
The length at temperature 180°C = L
Therefore, from the given relation, for change in length, ΔL, we have;
ΔL = α × L₀ × ΔT
The amount the temperature changed ΔT = 180°C - 40°C = 140°C
Therefore, the change in length, ΔL, is found as follows;
ΔL = α × L₀ × ΔT = 1.24 × 10⁻⁵/°C × 40 × 140°C = 0.07 cm
Therefore, L = L₀ + ΔL = 40 + 0.07 = 40.07 cm
The length at temperature 180°C = 40.07 cm
(b) Given that the length at T = 120°C is 65 in., we have;
The temperature at which the new length is sought = 90°C
The amount the temperature changed ΔT = 90°C - 120°C = -30°C
ΔL = α × L₀ × ΔT = 1.24 × 10⁻⁵/°C × 65 × -30°C = -0.024375 inches
The length, L at 90°C is therefore, L = L₀ + ΔL = 65 - 0.024375 = 64.976 in.
The length at temperature 90°C = 64.976 inches
(c) L = L₀ + ΔL = L₀ + α × L₀ × ΔT = L₀ + α × L₀ × (T - T₀)
Therefore;
L = 60 + α × 60 × (T - 150°C)
L = 60 + α × 60 × T - 9000 × α
L(T, α) = 60·α·T - 9000·α + 60
An ice cube is left on the kitchen counter. After some time, the ice cube melts into a small puddle of water.According to the law of conservation of mass, how does the mass of the puddle of water compare to the mass of the original ice cube
Answer:
Mass of the water is equal to the mass of ice
Explanation:
When ice melts, the mass remains the same even though its volume decreases leading to a decrease in density of water.
The mass remains the same because according to the law of conservation of mass, mass can neither be created nor destroyed. Since mass is neither created nor destroyed in the process of melting, the mass of water must remain the same.

When setting up a conversion, where does the initial unit go in the conversion factor?
Answer:
All these conversion factors are equal to 1. If it doesn't seem obvious at first, think about it for a second. Realize that 1 minute is equivalent to 60 seconds. Simply replace 1 minute in the fraction with its equivalent 60 seconds and it becomes clear that 60 seconds / 60 seconds = 1. Numerator and denominator are equivalent; they are just expressed differently.
Explanation:
The initial unit cancels out and goes into the new unit
In science, we often need to convert from one unit to another to ensure accuracy of our calculations.
Let's say i want to convert 500 minutes to seconds.
The conversion factor is as follows;
60 seconds make 1 minute
x seconds make 500 minutes
x = 60 seconds * 500 minutes/1 minute
x = 30,000 seconds
Hence the initial unit which is "minutes" is canceled out and the new unit "seconds" remains.

Which statement correctly describes hydrogen bonds? Which statement correctly describes hydrogen bonds? They hold together adjacent water molecules. They form when opposite charges repel each other. They happen only between water molecules. They form between the hydrogen atoms of different water molecules.
Answer:
They form between the hydrogen atoms of different water molecules.
Explanation:
A hydrogen bond is always a dipole-dipole bond. It is an attraction between a slightly positive atom of a molecule with the negative atom of the another molecule containing hydrogen. Thus, in a water molecule, oxygen atom will attract the electrons in the O–H bonds. Its interaction always involves a hydrogen atom.
They form between the hydrogen atoms of different water molecules is the correct statement about hydrogen bonds.
A hydrogen bond refers to a kind of bond that occurs from the attraction between a hydrogen atom and a negatively charged oxygen, fluorine, or nitrogen atom.
This attraction, for its part, is known as a dipole-dipole interaction and links the positive pole of one molecule with the negative pole of another.
Oxygen is very electronegative, that is, it attracts electrons from the bond much more strongly than hydrogen.This dipole-dipole interaction between water molecules is known as hydrogen bond.Water molecules can form hydrogen bonds with other molecules.Therefore, we can conclude that they form between the hydrogen atoms of different water molecules is the correct statement about hydrogen bonds.
