B. mass
C. density
D. chemical composition
The question is incomplete, the complete question is;
An alcohol thermometer makes use of alcohol's changing _______ in order to measure temperature. As the temperature goes up, the alcohol contained in the thermometer increases in volume, filling more of the thermometer's tube.
A.
mass
B.
state
C.
chemical composition
D.
density
Answer:
D.
density
Explanation:
Every kind of thermometer makes use of a change in a particular physical property of a substance as a measure of temperature. It must be a property that changes with temperature.
Density of a substance changes with temperature. Even though the mass of alcohol in glass remains constant, but its volume increases or decreases with change in temperature leading to a change in volume and consequently a change in density of the alcohol in glass. This change is used as a measure of the change in temperature.
Based on the image below, what is the displacement of the sound wave for Sound A + B at 0.1025 seconds?
A. -0.3316
B.0.3316
C.0.6255
D.1.6162
Answer:
The displacement of the sound wave for Sound A + B at 0.1025 is;
D. 1.6162
Explanation:
The sum of the displacement of two sound waves is given by the principle of superposition as follows;
y(x, t) = [tex]y_m[/tex]·sin(k·x - ω·t) + [tex]y_m[/tex]·sin(k·x - ω·t + ∅)
Therefore, by the property of the superposition of waves, the amplitudes of linear waves are added linearly when they meet at the same point at a the same time
The given parameters for the wave are;
The time at which the value of the wave amplitude are given, t = 0.1025 seconds
The displacement of the sound wave A at the given time, "t" is A = 0.9739
The displacement of the sound wave B at the given time "t" is B = 0.6423
Therefore, the displacement of the sound A + B = 0.9739 + 0.6423 = 1.6162
What kind of fossil is made when a creature is buried under sediment and as that sediment forms into rock the hard materials like bones of the organism are formed into the rock?
Answer:
Mold fossil
Explanation:
It's called a mold fossil because they are formed when sediments bury an organism and then the sediments are changed into rock; then the organism decays thereby leaving a cavity in the shape of the organism

Dinitrogen pentoxide is used in the preparation of explosives. If 7.93 mol of
dinitrogen pentoxide undergoes simple decomposition, what volume of Oz(9) is
produced at 48.0 °C and 125 kPa?
The volume of O₂ produced: 84.6 L
Further explanationGiven
7.93 mol of dinitrogen pentoxide
T = 48 + 273 = 321 K
P = 125 kPa = 1,23365 atm
Required
Volume of O₂
Solution
Decomposition reaction of dinitrogen pentoxide
2N₂O₅(g)→4NO₂(g)+O₂ (g)
From the equation, mol ratio N₂O₅ : O₂ = 2 : 1, so mol O₂ :
= 0.5 x mol N₂O₅
= 0.5 x 7.93
= 3.965 moles
The volume of O₂ :

how many atoms are in 0.340 moles of sodium
The number of atoms that are in 0.340 moles of sodium is 2.047×10²³ atoms.
What is Avogadro's number?Avogadro's number is equal to 6.022×10²³ which gives idea about the number of atoms present in one mole of any substance.
i.e. In 1 mole = 6.022×10²³ atoms
Given moles of sodium = 0.34 mol
Number of atoms of sodium in given moles will be calculated as:
No. of Na atoms = 0.34mol × 6.022×10²³ atoms/mol = 2.047×10²³ atoms
Hence required number of atoms are 2.047×10²³ atoms.

When scientists create a representation of a complex process, they are

c. classifying
b. predicting
d making models.
a.
Please select the best answer from the choices provided
А.
B
D
Answer:
d making models.
Explanation:
When scientists create a representation of a complex process, they are inferring that they are making models.
A model is an abstraction of the real world or a complex process. Models are very useful in developing solutions to processes that are not easily simplified.
The models allow a part of a body to be simply studied. Through this simple abstraction, extrapolations to other parts of the system can be deduced. This can give very useful insights into the other parts of the system. The heterogeneity of complex processes is a huge limitation to understanding them. A homogenous part can be modelled and used to understand the system.Answer:
D. making models.
Explanation:
Why are noble gases, like helium and krypton, unlikely to form a bond?
A. They do not have valence electrons and therefore cannot form bonds by sharing or trading
electrons.
B. They always have an equal number of protons and electrons.
C. They have full valence
orbitals and already have low energy.
D. They are nonmetals and gases and therefore their ionization energy is too high to form a bond.
Answer:
The valence electrons are the only parts of an atom that make chemical bonds. Noble gases don't form chemical bonds because they have a full outer shell (8 electrons).
Hi, can someone help me balance this chemistry equation:
H2SO4 + RbOH -> Rb2SO4 + H2O
H2SO4 + 2RbOH -> Rb2SO4 + 2H2O
If you want an explanation, keep reading.
In the first portion, there are two hydrogen ions and four sulfate ions.
The second portion has one rubidium ions and one hydroxide ion.
On the other side of the equation, in order to keep those two rubidiums balanced, you'll need to add a two at the beginning of the second portion, but in that process you are giving a second hydroxide value.
Back to the right side, there is there is water (H2O).
On the first portion, there were two hydrogen ions. The second portion also has two hydroxides because of the value change (adding the two to the front).
So on the fourth portion, you'd have to add another two so you could balance the four hydrogen ions (H2 and 2OH) and the two oxygen ions (2OH).
I hope this was easy to understand.

We add 5.0 g of sugar to 100 mL of water.
What is the mass of the solution?
The mass of the solution : 105 g
Further explanationGiven
5 g sugar
100 ml water
Required
The mass of the solution
Solution
Density is a quantity derived from the mass and volume
Density is the ratio of mass per unit volume
Density formula:
[tex]\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}[/tex]
ρ = density
m = mass
v = volume
Density of water = 1 g/ml
So mass of water :
= density x volume
= 1 g/ml x 100 ml
= 100 g
So total mass of solution :
=mass sugar+mass water
= 5 g + 100 g
= 105 g
What type of plate boundary (divergent, convergent, or transform) is typically
associated with sliding or shear forces?
convergent
transform
divergent
Answer:
transform
Explanation:
The type of plate boundary associated with sliding or shear forces is a transform plate boundary.
Two or more plates slides laterally past one another due to presence of shear forces acting on them.
In this margin, there is often an occurrence of earthquake. For a divergent margin, plates move apart and away from one another. This leads to the creation or formation of new crusts. At a convergent margin, two plates collides, a plate can subduct under another or both can become uplifted. Tectonic margins are known for their various activities.Answer:
convergent

Which of these metal oxides would you be unable to reduce to pure metal using carbon?
zinc oxide
Coppes oxide
calciumoxide
iron oxide
Answer:
calcium oxide
Explanation:
its stable
There are several metals which can be used to reduce the metal oxides to corresponding metals. Carbon is an efficient reducing agent. Here Calcium oxide cannot be reduced to calcium by carbon. The correct option is C.
What is metal oxide?The reaction of metals with oxygen result in the formation of oxygen containing compounds called metal oxides. The binary compounds of oxygen with lesser electronegative elements are called oxides. Most of the stable oxides have 'O' in its -2 oxidation state. Na₂O, CO₂, etc. are some oxides.
Carbon is a reducing agent and it is present above the elements like 'Zn', 'Cu', 'Fe', 'Ag', etc. in the electrochemical series. But the oxides of highly reactive metals cannot be reduced with carbon. Because these metals have more affinity for oxygen than carbon.
The highly reactive metals are extracted by using the electrolytic reduction of their molten chloride. It is not possible for carbon to reduce the oxides of metals like 'Na', 'Ca', 'Al', etc.
Thus the correct option is C.
