The new volume of the gas bubble as its temperature is heated to the given value and pressure increased is 4.14L.
Combined gas law
Combined gas law put together both Boyle's Law, Charles's Law, and Gay-Lussac's Law. It states that "the ratio of the product of volume and pressure and the absolute temperature of a gas is equal to a constant.
It is expressed as;
P₁V₁/T₁ = P₂V₂/T₂
Given the data in the question;
Initial volume of the gas V₁ = 2.3Lat STP
Initial pressure P₁ = 1.0atmInitial temperature T₁ = 273.15KFinal temperature T₂ = 984KFinal pressure P₂ = 1520mmHg = 2.0atmFinal volume V₂ = ?To calculate the new volume the gas, we subtsitute our given values into the expression above.
P₁V₁/T₁ = P₂V₂/T₂
P₁V₁T₂ = P₂V₂T₁
V₂ = P₁V₁T₂ / P₂T₁
V₂ = ( 1.0atm × 2.3L × 984K ) / ( 2.0atm × 273.15K )
V₂ = 2263.2LatmK / 546.3atmK
V₂ = 4.14L
Therefore, the new volume of the gas bubble as its temperature is heated to the given value and pressure increased is 4.14L.

What mass of kool-aid is needed to make a 0.5-M solution from 100 mL?
Answer:
but purely citric acid synthetic Acid whose moller mass is equal to 192 g per mole. Okay, so here we have Modernity is even McGarity is equal to 0.5 M and we have volume, so Volume is equal to 200 mililiters is equal to 0.1 liter Okay, so they are asking to calculate the mass of what u have Okay. So first of all, if we want to calculate the mass of then we have to calculate the number of moles. So maturity is equal to the number of moles per volume in liters . So you mean zero point sorry from this one number of moles is equal to So N is equal to m multiplied very weak. So that is equal to 0.1 and 0.5. So that is equal to 0.05 moles. Okay, now the mask is equal to the mass of cool eh is equal to the number of Okay. Number of 0.5 and it is multiplied by 92 g per mole. Then it is equal to 9.6 g. So this is the mass of a present.

If we accelerate a radioactive isotope of an element in a particle accelerator to a speed close to that of light, what would its observed mass be compared to its mass at rest
When the speed of the particle is close to that of light, it's observed mass would be infinitely large.
To answer the question, we need to know what observed mass is.
What is observed mass in relativity?This is the mass the body of an object in relativistic motion appears to have.
So, observed mass, m' = m/√(1 - β²) where
m = rest mass and β = relative velocity of isotope to light.Now, since the speed of the particle is close to that of light, β ≅ 1.
So, m' = m/√(1 - β²)
m' = m/√(1 - 1²)
m' = m/√(1 - 1)
m' = m/√0
m' = m/0
m' = ∞
So, when the speed of the particle is close to that of light, it's observed mass would be infinitely large.

Which best explains the relationship between evaporation and temperature?
A liquid evaporates slower at lower temperatures because the molecules are more spread apart and are not pushed as easily from the liquid’s surface.
A liquid evaporates faster at lower temperatures because the attractions are decreased and more particles can escape the surface of the liquid.
A liquid evaporates slower at higher temperatures because the vapor pressure of the liquid is higher, so fewer molecules can escape the surface.
A liquid evaporates faster at higher temperatures because more particles have a higher speed and can overcome attractions in the liquid.
Answer:
A liquid evaporated slow at higher temperature bz the vapour pressure of the is higher so few molecule can escape the surface
Answer:
The correct answer is D. A liquid evaporates faster at higher temperatures because more particles have a higher speed and can overcome attractions in the liquid.

Detective Gundy found several areas in a warehouse where fires appeared to have started. What can he MOST likely conclude from this
evidence?
A Someone deliberately set fires at different points around the warehouse
B. Several people accidentally dropped lit cigarettes around the warehouse
OC Strong winds spread the fire throughout multiple areas in the warehouse,
D. There was no accelerant used to start any of these fires
Given what we know, we can confirm that based on the evidence found, someone deliberately set fires at different points around the warehouse.
Why do we think the fires were deliberate?This has to do with the natural way in which fires spread. Fires that occur naturally or accidentally tend to concentrate in one place, then spread throughout the warehouse over time, however, this is not what the detective found. Instead, there are indications that multiple fires started simultaneously.
Therefore, given the very unlikely nature of this occurring naturally, we can confirm that based on the evidence found, someone deliberately set fires at different points around the warehouse.

When determining the cell potential for a hypothetical galvanic cell containing two different materials, how do we determine which substances comprise the anode and which comprise the cathode
To determine the substance that comprises the anode and the cathode in a galvanic cell is by determing ;
The material with the larger (more positive) standard reduction potential that will be the cathode.
Characteristics of a galvanic cellIn a galvanic cell, oxidation which leads to the loss of elctrons occurs at the anode, while reduction ( addition of elctrons ) occurs at the cathode. therefore the materials with a more positive standard reduction potential will be the cathode of the galvanic cell.
Hence we can conclude that The material with the larger (more positive) standard reduction potential will be the cathode.

How many grams of He are necessary to fill a balloon having a volume of 4.50 × 10^{3} mL to a pressure of 1.14 × 10^{3} torr at 25.0ºC?
The mass in grams of He are necessary to fill a balloon having a volume of 4.50×10³ mL to a pressure of 1.14×10³ torr at 25.0ºC is 1.104 grams.
How do we calculate the grams from moles?Mass (W) in grams from moles (n) will be calculated by using the below equation:
n = W/M, where
M = molar mass
Moles of helium gas will be calculated by using the ideal gas equation:
PV = nRT, where
R = universal gas constant = 62.363 L.torr / K.mol
P = pressure of gas = 1.14×10³ torr
V = volume of gas = 4.50×10³ mL = 4.50 L
n = moles of gas = ?
T = temperature = 25.0ºC = 298 K
On putting these values on the ideal gas equation, we get
n = (1140)(4.5) / (62.363)(298) = 5130 / 18584
n = 0.276 moles
Now we convert this moles into mass by using the first equation as:
W = (0.276mol)(4g/mol) = 1.104 g
Hence required mass of helium gas is 1.104 grams.

From the above reaction, state the:
a) Electropositive metal -
b) Less electropositive metal -
c) Reducing agent -
In the given chemical reaction iron is less electropositive metal and aluminum is more electropositive and behave as a reducing agent also.
What is electropositivity?Electropositivity is the ability of an atom of donation or losing of electrons easily.
From the given chemical reaction it is clear that oxidation state of iron changes from +3 to 0 & of aluminum is from 0 to +3. So in the above chemical reaction aluminum is more electropositive than iron metal. And aluminum is behave as a reducing agent as it helps in the reduction process by providing electrons.
Hence aluminum is electropositive metal and reducing agent, iron is less electropositive.
