Answer:
HNO3
Explanation:
The ability of an acid to act as a Brownstead-Lowry acid depends on it's proton donation ability.
A Brownstead-Lowry acid is a specie that donates hydrogen ions in solution.
Considering all the chemical species listed among the options, HNO3 has the greatest hydrogen donation ability. It then follows that HNO3 is the strongest Brownstead-Lowry acid among the species listed.

Referencing the reasoning you used from #1, explain the difference between objects that feel hot and those that
feel "cold".
Answer:
The temperature of the cold water is lower than the warm one. So, when we put the hand in the warm from the cold water, our hand will absorb heat, causing the hand to feel hot. Thus, we can conclude that the more heat it absorbs, the more hotter it is. Whereas the more heat it releases, the colder it is.

What mass of sulfur trioxide is formed from 96g of sulfur dioxide?
2 SO2+O2 –> 2 SO3
Answer:
120 g SO3
Explanation:
128 g SO2 -> 160 g SO3
96 g SO2 -> x
x= (96 g SO2 * 160 g SO3)/128 g SO2
x= 120 g SO3
The mass of sulfur trioxide, SO₃, formed is 120 g
The balanced equation for the reaction is given below:
2SO₂ + O₂ —> 2SO₃Next, we shall determine the mass of SO₂ that reacted and the mass of SO₃ produced from the balanced equation. This can be obtained as follow:
Molar mass of SO₂ = 32 + (16×2)
= 32 + 32
= 64 g /mol
Mass of SO₂ from the balanced equation = 2 × 64 = 128 g
Molar mass of SO₃ = 32 + (16×3)
= 32 + 48
= 80 g /mol
Mass of SO₃ from the balanced equation = 2 × 80 = 160 g
Thus,
From the balanced equation above,
128 g of SO₂ reacted to produce 160 g of SO₃.
Finally, we shall determine the mass of SO₃ by the reaction of 96 g of SO₂. This can be obtained as follow:
From the balanced equation above,
128 g of SO₂ reacted to produce 160 g of SO₃.
Therefore, 96 g of SO₂ will react to produce = [tex]\frac{96 X 160}{128}\\\\[/tex] = 120 g of SO₃.
Therefore, the mass of SO₃ formed is 120 g

Answer:
ozone (O3): inorganic
methane (CH4): organic
aluminum hydroxide (Al(OH)3): inorganic
butane (C4H10): organic
carbon monoxide (CO): inorganic
Explanation:
An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bonds, that is, a compound that is not an organic compound. Some simple compounds that contain carbon are often considered inorganic. Examples of inorganic compounds include carbon monoxide , carbon dioxide , carbonates, carbides , cyanides, cyanates, and thiocyanates. Most of these compounds are normal parts of mostly organic systems, including living organisms. When a chemical substance is classified as inorganic, it does not necessarily mean that it does not occur within
living things.
Organic compounds typically contain the carbon-hydrogen bonds. The carbon atoms often catenate and most organic substances occur in living systems and are products of biochemical reactions in living organisms. However, organic substances can also be synthetic and can be prepared in the laboratory.

A sample of a compound contains 60.0 g C and 5.05 g H. It’s molar mass is 78.12 g/mol. What is the compound’s molecular formula?
Answer:
C6H6
Explanation:
C : 60.0 g*1 mol/12 .01g = 5.00 mol
H: 5.05 g * 1 mol/1.01 g= 5.10 mol
C:H = 5.00 mol : 5.10 mol = 1:1
CH is an empirical formula
Molar mass (12.01 +1.01)=13.02 g/mol
78.12g/mol /13.02 g/mol =6
Molecular formula is the empirical that was taken 6 times (CH)6 = C6H6

List and describe the steps of energy transfers that occur that allow a digital recording to be played through a speaker and ultimately become sound waves.
Answer:
1) Sound waves are stores as electrical signal in the digital recording.
2) the electrical signal of the digital recording is transcribed and sent to the voice coils.
3) the voice coil changes this electrical signal into varying magnetic fields.
4) The magnetic field pushes and pulls the diaphragm of the speakers.
5) the pushing and pulling of the diaphragm generates sound waves in the speaker.
If you decrease the amount of gas, what happens to the pressure? Explain WHY.
Answer:
Gas particles exert pressure by colliding with the walls of their container. If you reduce the volume, you are effectively increasing the density of the particles and they will collide with the walls more frequently, leading to an increase in pressure.

This group of fungi has reproductive cells with flagella so that they can swim
Answer:
The answer would be chytrids.
Chytridiomycota (chytrids) is a group of fungi that has reproductive cells with flagella so that they can swim.
What is Chytridiomycota?The fungus known as the amphibian chytrid fungus only infects frogs. A frog uses its skin to maintain homeostasis. The chytrid fungus ruins the frog's ability to swallow, exchange ions, and function normally when it affects its skin.
The fungus targets the keratin-containing areas of a frog's skin. Frogs have trouble breathing because they use their skin for respiration.
As a class of fungi, chytrids are regarded as the most basic. They are primarily aquatic, and the only fungus cells known to contain flagella are those of the gametes. They can reproduce asexually or sexually; the latter method produces zoospores.
Therefore, a class of fungi known as chytrids possesses reproductive cells with flagella that allow them to swim.
