The states of matter can be solid, liquid, and gas.
Explanation:
The change in the state of matter can change the utility of the materials. Like, water in the liquid state when changed into solid ice can be used as ice cube and in the gaseous vapors can be used for steaming food items.
The stepping stone is a stone which is used for roadside pavements. It is used for walking. It can be prepared using liquid mixture of cement and concrete into a mold and it is converted into solid mass on drying.
The earth is made out of layers that separate according to their densities.
The density of each layer is affected by the composition of the material and the amount of pressure it is under.
The thinnest and least dense layer is known as the Crust.
The layer under the most pressure is known as the core.
Such high amounts of pressure cause this layer to remain in a Solid State of matter even though the nickel and iron are at such a high temperature.
On the other hand, the outer core remains in a molten state of matter even though it is made out of the same materials as the inner core since there is not enough pressure to change it to a solid.
Explanation:
The above question now updated with the missing words provide information about how the compositional layers of the earth's crust are formed.
The three major determinants as already explained about how the layers have come to be are:
Composition of MaterialPressure on the material and their densityThe Crust (which is the outmorst layer) comprises of more silica.
The Mantle is a combination of silica, magnesium, and iron.
The core is a combination of oxygen, nickel iron and sulphur.

B
Explanation:
According to the text, the hurricane did not produce any fatalities but did cause damage to houses, which made homeowners face weeks, if not months, of rebuilding. As a result, there was an increase in the demand for building materials. The supply-demand relation can be demonstrated in the attached figure. An increase in the demand makes a right-shift of the demand curve. Given that the supply remains constant, the price will increase.
Option A, C and D are incorrect as the text did not mention the supply side of building materials yet.

Name and Title:
Colleen DeBruin, Hillary Mulkavits, 11/18/2020, compounds lab.
Objectives(s):
to build chemical compounds from known elements
Hypothesis:
if I use oxygen hydrogen and carbon then I can make five new compounds in four minutes
Procedure:
The materials and procedures are listed in your virtual lab. You do not need to repeat them here. However, you should note if you experienced any errors or other factors that might affect your outcome. Using your summary questions at the end of your virtual lab activity, please clearly define the dependent and independent variables of the experiment.
Data:
Record the composition of each of your compounds below. Be sure to include the number of atoms for each element. An example has been supplied for you.
Compound Name Chemical Formula Sodium (Na) Atoms Calcium (Ca) Atoms Hydrogen (H) Atoms Oxygen (O) Atoms Carbon (C) Atoms Chlorine (Cl) Atoms
Ex: Sodium
hypochlorite NaClO 1 0 0 1 0 1
Water H20 o 0 1 2 0 0
Glucose C6H12O6 0 0 12 6 6 0
Formic/methanoic acid HCOOH 0 0 2 2 1 0
Butanoic Acid C3H7COOH 0 0 8 2 4 0
Carbon Dioxide C02 0 0 0 2 1 0

Conclusion:
Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.
I found as many combinations of carbon hydrogen and oxygen as possible
If there is a job that combines elements you would be doing that every day making it an every day matter
elements are like people, they are all different causing them to react differently and be more reactive
H20 has four because there are 2 oxygen and one hydrogen because of the numbers in the name of the compound
Yes because two elements can form two different types of bonds causing different outcomes
Explanation:
Name and Title:
name, teacher's name, date, chemical components lab.
Objectives(s):
The purpose of this lab was to use elements and make chemical compounds.
Hypothesis:
If I use sodium, carbon, and hydrogen, then I can make at least 5 new compounds in 5 minutes.
Procedure:
The independent variable is the number and types of elements I picked for my compounds. The dependent variable is the types of compounds made.
Data:
Record the composition of each of your compounds below. Be sure to include the number of atoms for each element. An example has been supplied for you.
