Answer:
The temperature will be 384.7 K
Explanation:
Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure, by means of a constant of proportionality that is applied directly. For a given sum of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of the movement of the gas molecules. .
In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:
[tex]\frac{V}{T} =k[/tex]
Having an initial state 1 and a final state 2, the following is true:
[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]
In this case:
V1= 33.9 LT1= 12.4 C= 285.4 K (being 0 C= 273 K)V2= 45.7 LT2= ?Replacing:
[tex]\frac{33.9 L}{285.4 K} =\frac{45.7 L}{T2}[/tex]
Solving:
[tex]T2=45.7 L*\frac{285.4 K}{33.9 L}[/tex]
T2= 384.7 K
The temperature will be 384.7 K

Iron is extracted from its ore (hematite) in the blast furnace. Which gas is produced as a waste product?
Answer:
CO2
Explanation:
CO2 or carbon dioxide is produced when iron is extracted from its ore. Carbon monoxide Co is used as reducing agent in iron extraction. In this reaction iron ore is reduced to iron and CO is oxidized to CO2 or carbon dioxide which is released in the process. There extraction of iron is redox reaction.

Why wasn't the water pasteurized? I chose Claim 1: If you follow the instructions, the POW kits will always heat the water above the correct temperature for pasteurization (65°C), but some people didn't follow the instructions Can someone help me support it?
Answer:
Claim 1- The evidence that supports my claim because Evidence Card b says “One man got sick, but his two children did not. He used water from Whip River. He used the cube to heat the first pitcher of water, which he gave to his kids, and then reused the cube without reheating for the second pitcher, which he drank himself.” My first piece of evidence is that if you don't follow thee directions then something bad would happen

A mixture of PCl5(g), PCl3(g), and Cl2(g) is in a 1.00 L reaction vessel. The total pressure of the reaction system is 1.40 atm at equilibrium. Then the volume of the reaction vessel is reduced from 1.00 L to 0.50 L and equilibrium is re-established at constant temperature. What is the total pressure of the system at this point?
Answer:
The total pressure immediately after the volume reduction is 2.8 atmospheres
Explanation:
The question parameters are as follows;
The initial volume of the reaction vessel, V₁ = 1.00 L
The initial pressure of the reaction system, P₁ = 1.40 atm
The final volume of the reaction system, V₂ = 0.50 L
With the assumption that the gas mixture behaves as an ideal gas, and the temperature is constant, by Boyle's law we have;
P₁·V₁ = P₂·V₂
Where;
P₁ = The initial pressure in the reaction vessel
V₁ = The initial volume in the reaction vessel
P₂ = The total final pressure in the reaction vessel after the reduction in the vessel volume
V₂ = The final volume in the reaction vessel
∴ P₂ = P₁·V₁/V₂
From which we have;
P₂ = 1.40 atm × 1.00 L/(0.50 L) = 2.8 atm
The total final pressure in the reaction vessel, P₂ = 2.8 atm.

Please answer the following questions:
Why does Na have only one dot?
Why do none of these diagrams show more than 8 dots?
What relationship do you notice between the dots in these two charts?
The number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table. Why? (Hint: Octet Rule (Links to an external site.))
Hello! Here's the answer I was able to come up with:
Why does Na have only one dot?
Sodium, or Na, has only one valence electron. (This makes the atom tend to participate in ionic bonding and "give" its single valence electron to an atom like chlorine.)
Why do none of these diagrams show more than 8 dots?
It is physically impossible for an atom to have more than 8 electrons in its valence layer, according to the Octet Rule.
What relationship do you notice between the dots in these two charts?
The dot diagram for each element represents the number of electrons each element will have in its outermost, or valence, shell. (2-8-8)
The number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table. Why?
An atom can have a maximum of two electrons in its innermost layer. Hydrogen and helium have only one and two electrons, respectively, so they don't have enough electrons to actually have more than one layer. Therefore, their outermost layer is, in fact, their only layer. This is why the number of dots that hydrogen and helium have in their dot diagram is the same as the number of electrons shown for them on the Periodic Table.

i just need an explanation :) so the problem was " what is the mass of 5 molecules of water(H2O) , in grams?" my teacher said the answer is 1.50 x 10^-22 but i dont understand why. why is it not 1.50 x 10^24, why is the exponent negative?
Answer:
Explanation:
The exponent is negative because water molecules are absolutely tiny. You can't see a molecule of water on the palm of your hand with your naked eyes, right? If a the mass of a molecule was 1.50 x 10^24, it'd be HUGE... like absolutely massive (possible the size of your city). Molecules are just tiny, tiny particles

The teacher asked the students to design an experiment that would demonstrate that temperature will affect the pressure of a gas. Which of the
following would be a valid experiment that shows the correct relationship between gas temperature and pressure?
The correct option is option A. when the students check the air pressure of bicycle tires, once by keeping it out in the winter and noticing the air pressure being decreased and after by keeping the bicycle inside at room temperature and noticing that the air pressure has increased.
How are pressure and temperature of a gas related ?
According to Gay lussac's law, the temperature and pressure of a gas are directly proportional to each other, provided the volume is constant.
When the temperature of a gas is increased, the molecules gain more kinetic energy and hence the frequency of them hitting the walls of the container increases which basically implies that the pressure increases.
On the other hand when the temperature is low, the molecules do not have substantial kinetic energy to hit the walls of the container frequently, that is the pressure decreases.
When the bicycle tires were kept out in the winter, the low temperature decreased the air pressure inside the tires. While when they were warmed at room temperature, the pressure inside the tires increased.
Therefore, the correct option is option A. when the students check the air pressure of bicycle tires, once by keeping it out in the winter and noticing the air pressure being decreased and after by keeping the bicycle inside at room temperature and noticing that the air pressure has increased.

how much is the mass of a man if
he has to do 2500 joules of work in
climbing a tree 5 meters tall
Answer:
50kg
Explanation:
Using the formula for potential energy, which is the amount of energy due to position;
P.E = m × g × h
Where;
m = mass (kg)
g = acceleration due to gravity (10m/s²)
h = height (metres)
According to the information provided in this question, m = ?, P.E = 2500J, h = 5m
Using P.E = m × g × h
m = P.E/gh
m = 2500/(5 × 10)
m = 2500/50
m = 50kg
The mass of the man is 50kg.

Calculate: A. Mercury has a specific Heat Capacity of 0.14 J/goC. How much heat is needed to raise the thermometer temperature 15 oC to 95 oC. There is 5 g of mercury in the thermometer.
Answer:
[tex]\boxed {\boxed {\sf 56 \ Joules}}[/tex]
Explanation:
We are given the mass, specific heat, and temperature, so we must use this formula for heat energy.
[tex]q=mc \Delta T[/tex]
The mass is 5 grams, the specific heat capacity is 0.14 Joules per gram degree Celsius. Let's find the change in temperature.
ΔT= final temperature - initial temperature ΔT= 95°C - 15°C = 80°CWe know the variables and can substitute them into the formula.
[tex]m= 5 \ g \\c= 0.14 \ J/ g \ \textdegree C \\\Delta T= 80 \ \textdegree C[/tex]
[tex]q= (5 \ g )( 0.14 \ J/ g \ \textdegree C ) ( 80 \ \textdegree C)[/tex]
Multiply the first numbers. The grams will cancel.
[tex]q= 0.7 \ J/ \textdegree C(80 \ \textdegree C )[/tex]
Multiply again. This time the degrees Celsius cancel.
[tex]q= 56 \ J[/tex]
56 Joules of heat are needed.

(atomic mass: C = 12.01, H = 1.01, 0 = 15.99)
Answer:
62.00
Explanation:
H2 means that there are two moles of hydrogen so multiply the atomic mass by two (1.01 × 2 = 2.02)
C only has one mole sp leave 12.01 alone
And multiply oxygen by 3 because there are three moles of oxygen (15.99 × 3 = 47.97)
Add them all together!
2.02 + 12.01 + 47.97 = 62.00 for molar mass
