Explanation:
Though both the molecules contain carbon and oxygen, the general difference between them lies in their number of oxygen of atoms carried by them; as carbon dioxide (CO2) has one carbon atom and two oxygen atoms, while carbon monoxide (CO) has one carbon and one oxygen atom.
Carbon Dioxide is naturally present in our atmosphere and as it is excreted out during the process breathing by the animals and humans. On the other hand, Carbon Monoxide is toxic, and it produces suffocation if it builds while incomplete combustion of coal, fossil fuels, etc.
In the layman language, both the terms are sometimes used interchangeably and create confusion. As they have few similarities and incorporates carbon and oxygen as well, and are the byproducts of the things which carry carbon like fuels, coals, woods, and natural gas.
We all are aware of the three states of matter, which are Solid, Liquid and Gas. In this context, we will be discussing the two most common gases present in our atmosphere, how they vary from each other, their effects and their similarities. These gases are Carbon Dioxide and Carbon Monoxide.
Answer:
The major similarities between molecules of carbon monoxide, diatomic oxygen and carbon dioxide is that they all exist in gaseous states in their natural forms. Each of them also have low molecular weight of less than 70g/mol.
The difference between them is that the carbon monoxide is formed from incomplete combustion and is a toxic gas while carbon dioxide is an end product of respiration and is used by plants for photosynthesis. Oxygen on the other hand is essential for respiration and is the end product of photosynthesis.
Carbon dioxide and Carbon monoxide look most alike as they have the same elements which include Carbon and Oxygen but only different in the number of atom composition

Relate how a household sponge and water can be used to model
the concept of an unsaturated solution, a saturated solution, and a supersaturated
solution.
The sponge is unsaturated when it is taking in more water. It becomes saturated when it stops taking in water. It is supersaturated when water starts oozing out from the sponge.
A saturated solution contains just as much solute as it normally hold at a particular temperature. An unsaturated solution contains less solute than it can normally hold at a particular temperature. A supersaturated solution contains more solute than it can normally hold at a particular temperature.
We can use a sponge to model these three scenario as follows;
Water continues to enter into the sponge when it is unsaturated, this continues until the sponge becomes saturated with water and takes in no more water. When the sponge becomes supersaturated, water begins to ooze out from the sponge because it can no longer hold more water.

A mixture of hydrogen, nitrogen, and water vapor has a total pressure of 864 mmHg. The partial pressure of hydrogen is 220 mmHg and that of nitrogen is 410 mmHg. What is the partial pressure of water vapor?
Answer:
As per Dalton's law of Partial pressure,
The total pressure of a mixture of gases is equal to sum of partial pressure of individual components of the mixture.
So,P=P_H+P_N+P_WP=P
H
+P
N
+P
W
\implies 864\ mm=220\ mm+410\ mm+P_W\implies⟹864 mm=220 mm+410 mm+P

=864−630=234 mm of Hg.
Explanation:
"The partial pressure of water vapor is 234 mm Hg."
What is partial pressure?
The force that a gas exerts is known as partial pressure. The total pressure of a mixture of gases is equal to the sum of their partial pressures.
Partial pressure can be calculated by using the formula: [tex]P_{Total} =P_{N} +P_{H} +P_{H}[/tex]

If the Moon orbited Earth twice as fast, how many high tides would occur in one day?
Four high tides would occur in one day, if the moon orbited Earth twice as fast.
What are high tides?The tide when the water is at its greatest elevation.
At the moment, high tides occur twice a day. So if the moon orbits the earth twice as fast, high tides will occur twice as many, which means four times a day.
High tides occur 12 hours and 25 minutes apart. It takes six hours and 12.5 minutes for the water at the shore to go from high to low, or from low to high.
The best-known effect of the moon is its gravitational pull on Earth's oceans, which results in two high tides and two low tides every day.
But if the moon were half the distance from Earth as it is now, the tides would be eight times higher.

15.24. Calcium hydroxide, also known as slaked lime, is used in industrial processes in which low concentrations of base are required. Only 0.16 g of Ca(OH)2 dissolves in 100 mL of water at 25°C. What is the concentration of hydroxide ions in 250 mL of a solution containing the maximum amount of dissolved calcium hydroxide?
The concentration of the hydroxide ions, OH¯ in 250 mL of the solution containing the maximum amount of dissolved calcium hydroxide is 0.01728 M
We'll begin by calculating the number of mole of in 0.16 g of Ca(OH)₂. This can be obtained as follow:
Mass of Ca(OH)₂ = 0.16 g
Molar mass of Ca(OH)₂ = 40 + 2[16 + 1] = 74 g/mol
Mole of Ca(OH)₂ =?Mole = mass / molar mass
Mole of Ca(OH)₂ = 0.16 / 74
Mole of Ca(OH)₂ = 0.00216 mole Next, we shall determine the molarity of the stock solution of Ca(OH)₂.Mole of Ca(OH)₂ = 0.00216 mole
Volume = 100 mL = 100 / 1000 = 0.1 L
Molarity of Ca(OH)₂ =?Molarity = mole / Volume
Molarity of Ca(OH)₂ = 0.00216 / 0.1
Molarity of Ca(OH)₂ = 0.0216 MNext, we shall determine the molarity of the diluted solution. This can be obtained as follow:Volume of stock solution (V₁) = 100 mL
Molarity of stock solution (M₁) = 0.0216 M
Volume of diluted solution (V₂) = 250 mL
Molarity of diluted solution (M₂) =?M₁V₁ = M₂V₂0.0216 × 100 = M₂ × 250
2.16 = M₂ × 250
Divide both side by 250
M₂ = 2.16 / 250
M₂ = 0.00864 MThus, the molarity of the diluted solution is 0.00864 M
Finally, we shall determine the concentration of the hydroxide ions, OH¯ in the diluted solution. This can be obtained as follow:Ca(OH)₂(aq) —> Ca²⁺(aq) + 2OH¯(aq)
From the balanced equation above,
1 mole of Ca(OH)₂ contains 2 moles of OH¯
Therefore,
0.00864 M Ca(OH)₂ will contain = 2 × 0.00864 = 0.01728 M OH¯
Thus, the concentration of the hydroxide ions, OH¯ in 250 mL of the solution containing the maximum amount of dissolved calcium hydroxide is 0.01728 M

What is the frequency of red light with a wavelength of 645 nm?
Answer:
4.64E14
Explanation:
First convert 645 nm to m = 6.4500E-7m. The equation for finding v with these values is the speed of light/wavelength. so 2.998E8/6.4500E-7m.
so your v or frequency would equal 4.64E14
Fun fact you know this is visible light because the visible light range is within the E14 range.

How does density affect sinking and floating in water?
Answer:
Density is a measure of how heavy something is compared to its size.
If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.
Density is a characteristic property of a substance and doesn’t depend on the amount of substance.
Explanation:
If you compared the weight of wood and an equal amount, or volume, of water the sample of wood would weigh less than the sample of water. This means that wood is less dense than water. Since wood is less dense than water, wood floats in water, no matter how big or small the piece of wood is.
A student might want to know why a boat made out of steel can float when steel is more dense than water. This is not an easy question and requires a different approach than what students have seen so far. We do not necessarily recommend the following explanation for 5th graders but here is the idea:
An object floats when it displaces a volume of water that has a mass equal to the mass of the object. So if a material like steel is shaped into a boat and made larger and larger, it will displace more and more water. When it is large enough to displace a volume of water that has a mass equal to the mass of the boat, the boat will float.
