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.

If a woman is pushing a cart 125 N forward and gravity is pushing 50 N backwards on the cart and a child is pushing 25 N backwards on the cart what is the net force?
Answer: 50N forward
Explanation:
A woman is pushing a cart 125N forward (+125N)
Gravity is pushing 50N backwards (-50N)
A child is pushing 25N backwards (-25N)
The net force is the total sum of these forces.
125N+(-50N)+(-25N)
125N-50N-25N
125N-75N
50N forward because it's positive

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

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.

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.
How much NaOH (in grams) is needed to prepare 463 mL of solution with a pH of 10.020?
Answer: [tex]1.94\times 10^{-3}g[/tex] of NaOH
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
[tex]pH=-\log [H^+][/tex]
Putting in the values:
[tex]10.020=-\log[H^+][/tex]
[tex][H^+]=9.55\times 10^{-11}[/tex]
[tex][H^+][OH^-]=10^{-14}[/tex]
[tex][OH^-]=\frac{10^{-14}}{9.55\times 10^{-11}}=1.05\times 10^{-4}M[/tex]
[tex]NaOH\rightarrow Na^++OH^-[/tex]
[tex]Molarity=\frac{moles\times 1000}{\text {Volume in ml}}[/tex]
[tex]1.05\times 10^{-4}M=\frac{moles\times 1000}{463ml}[/tex]
moles = [tex]4.86\times 10^{-5}[/tex]
Mass of [tex]NaOH=moles\times {\text {Molar mass}}=4.86\times 10^{-5}\times 40=1.94\times 10^{-3}g[/tex]
Thus [tex]1.94\times 10^{-3}g[/tex] of NaOH is needed to prepare 463 mL of solution with a pH of 10.020
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
