1. Which statement best describes why a gas is
easily compressible while most solids
are incompressible?
A. The molecules of a gas are much smaller
than those of a solid.
B. The molecules of a solid are not attracted to
one another.
C. The molecules of a gas are much further
apart than those of a solid.
D. The molecules of a solid are much larger
than those of a gas.
C) The molecules of a gas are much further
apart than those of a solid.
A gas is easily compressible while most solids are incompressible because the molecules of gas are much further apart than those of a solid.
What are gases?Gases is one of the four fundamental state of matter.
Gases can be defined as phase of matter that neither have fixed shape nor have fixed volume.
The molecules of gases are far apart from each other as compare to other phases of matter.
The change in properties of volume is known as compressibility and those fluid whose volume changes are known as compressible fluids or gases.
The fluids which does not compressed or expanded and its volume remain constant are known as incompressible fluids or gases.
Thus, gas is easily compressible while most solids are incompressible because the molecules of gas are much further apart than those of a solid.

Which statement describes a controlled experiment? A.) It has one group in which the controlled variable is tested, and another in which the manipulated variable is tested. B.) It has one group in which the responding variable is tested, and another in which the responding variable is not tested. C.) It has one group in which the manipulated variable is tested, and another in which the responding variable is tested. D.) It has one group in which the manipulated variable is tested, and another in which the manipulated variable is not tested.
Answer:C.) It has one group in which the manipulated variable is tested, and another in which the responding variable is tested
Explanation: hope this helps
The statement that describes a controlled experiment is that it has one group in which the manipulated variable is tested, and another in which the responding variable is tested (option C).
What is a controlled experiment?A controlled experiment is an experiment where one variable is tested at a time and all other variables are kept constant.
An experiment consists of a manipulated or independent variable, which is the variable changed, and a responding or dependent variable, which is the variable measured.
Therefore, statement that describes a controlled experiment is that it has one group in which the manipulated variable is tested, and another in which the responding variable is tested.

Describe how you would measure the density of a boat (how would you predict if it would float )
Answer:
Please find the description below
Explanation:
The density of a substance refers to its mass per unit of its volume i.e the amount of a substance contained in a given volume. The density is calculated using the formula:
Density = mass/volume
Using this formula, with the known value for mass and volume of the boat, the density of the boat can be calculated.
An object will FLOAT on a liquid substance if its density is lower than that of the liquid while it will SINK if it has a higher density than that of the liquid.
In this case, with a known density of water, which is 1g/cm^3 or 1000kg/m^3,
a boat placed on water will FLOAT if its density is <1g/cm^3 (less than) while it will SINK if its density is >1g/cm^3 (greater than).
If the density of water is 1.0 g/mL, what is the mass of 2.0 L of water?
Answer:
Density=1.0 g/mL
Volume=2.0 L
Mass=?
Density=mass/volume
Mass=density*volume
Mass=1.0*2.0
Mass=2g

This is an unreactive atom because it has completely filled out stable electrons in the outer shell.
8 electrons in the outer shell means stable.
Write and balance this equation. Solid iron reacts with fluorine gas to produce crystalline iron(III) fluoride.
Answer:
iron+flourine.............iron flouride
Fe+F2.............FeF3
the above reaction is not balanced
now to balance this reaction
2Fe+3F2...........2FeF3
now this reaction is balanced
The balanced equation is: 2Fe + 3F2 ⇒ 2FeF3
How to balance an equation?A chemical equation needs to be balanced if you want to make the wide variety of the atoms of the reactants equal to the variety of the atoms of the goods.
Given,
Iron + fluorine ⇒ Iron Flouride
Fe + F2 ⇒ FeF3
Now to balance this reaction:
2Fe + 3F2 ⇒ 2FeF3
This reaction is balanced.

What is mass in grams of 300 ml of salt water with a density of 1.30 grams per centimeter cubed
Answer:
The answer is
390 gExplanation:
The mass of a substance given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
Density = 1.30 g/cm³
volume = 300 mL
