At a certain temperature 3.24 moles of co2 gas at 2.15atm takes up a volume of 35.28 what is the temperature in celsius
Answer:
The temperature is 12.35 C.
Explanation:
An ideal gas is a theoretical gas that is considered to be composed of point particles that move randomly and do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
P * V = n * R * T
In this case:
P= 2.15 atmV= 35.28 Ln= 3.24 molesR= 0.082 [tex]\frac{atm*L}{mol*K}[/tex]T= ?Replacing:
2.15 atm* 35.28 L= 3.24 moles* 0.082[tex]\frac{atm*L}{mol*K}[/tex] * T
Solving:
[tex]T=\frac{2.15 atm* 35.28 L}{3.24 moles* 0.082\frac{atm*L}{mol*K}}[/tex]
T=285.5 K= 12.35 C (being 273.15 K= 0 C)
The temperature is 12.35 C.
The relation between the moles, volume, temperature, and pressure is given by the ideal gas equation. The temperature of a gas is 12.35 celsius.
What is the ideal gas law?The ideal gas law is the hypothetical gas law that depicts the relation between pressure, volume, moles of the compound, and the temperature of the gas.
The ideal gas equation is given as,
[tex]\rm PV = nRT[/tex]
Given,
Pressure (P) = 2.15 atm
Volume (V) = 35.28 L
Number of moles (n) = 3.24 mol
Gas constant (R) = 0.082
Temperature (T) = ?
Substituting values in the above equation, the temperature is calculated as:
[tex]\begin{aligned} \rm T &= \rm \dfrac{PV}{nR}\\\\&= \dfrac{2.15\times 35.28}{3.24 \times 0.082}\\\\&= 286.23 \;\rm K\end{aligned}[/tex]
Therefore, 12.35 degrees Celsius is the temperature of the gas.

El mercurio ha sido utilizado como elemento para medir la temperatura porque Es una mezcla. Al aumentar la temperatura se dilata con facilidad. Es un buen conductor del calor. Es un buen conductor de la electricidad.
Answer:
La respuesta correcta es: Al aumentar la temperatura se dilata con facilidad
Explanation:
El mercurio (Hg) es un elemento metálico que a temperatura ambiente es un líquido. Tiene la propiedad de dilatarse con facilidad al aumentar la temperatura, propiedad que ha sido utilizada en los termómetros de mercurio. En estos termómetros, el mercurio está dentro de un tubo de vidrio graduado con un bulbo para transmitir el calor. Al estar en contacto con un cuerpo más caliente (a mayor temperatura), el mercurio del interior del termómetro se dilata (expande su volumen) y asciende por el tubo indicando la temperatura correspondiente, graduada en el vidrio.
A slug travels the length of a log in 2 hours. If the slug's average speed is 1.5 cm / minute how long is the log
Answer:
The length of the log is 180 cm
Explanation:
From the question given above, the following data were obtained:
Time = 2 hours
Speed = 1.5 cm/min
Distance =?
Next, we shall convert 2 hours to minutes. This can be obtained as follow:
1 h = 60 mins
Therefore,
2 h = 2 × 60
2 h = 120 mins
Finally, we shall determine the Lenght of the log. This can be obtained as follow:
Time = 120 mins
Speed = 1.5 cm/min
Distance =?
Speed = distance / time
15 = distance / 120
Cross multiply
Distance = 1.5 × 120
Distance = 180 cm
Therefore, the length of the log is 180 cm
Answer:

cause that's the only one that makes sense because it goes: cell, tissues,organ,organ system , organism
1. the simplest unit of life - cell
2. a individual organ - would be made of different kinds of tissues
3. tissues - would be made of one kind of cell
4- an organ system - meets all the needs of a organism
also it wouldn't make sense for a individual organ to be made of only one kind of cell so yeah

A bottle contains 2.5 moles of KOH dissolved in water, and the molarity of the solution is 0.16 M.
What volume of solution is in this bottle?
Answer:
V = 15.6 L
Explanation:
Hello there!
In this case, according to the definition of molarity in terms of the moles of solute divided by the volume of the solution, it is possible for us to write:
[tex]M=n/V[/tex]
Thus, given the moles and concentration of the solution, we can find the volume as shown below:
V=n/M
Therefore, we plug in the given data to obtain:
V = 2.5mol /(0.16mol/L)
V = 15.6 L

A gas has a volume of 5.00 L at 20 degrees Celsius. What is the volume of gas at 150 degrees Celsius.
Answer:
7.22 L
Explanation:
From the question,
Applying Charles law,
V₁/T₁ = V₂/T₂...................... Equation 1
Where V₁ = Initial volume of gas, V₂ = Final volume of gas, T₁ = Initial Temperature of gas in Kelvin, T₂ = Final Temperature of gas in Kelvin
Make V₂ the subject of the equation
V₂ = (V₁×T₂)/T₁................. Equation 2
Given: V₁ = 5.00 L, T₁ = 20 °C = (20+273) K = 293 K, T₂ = 150 °C = (150+273) K = 423 K
Substitute these value into equation 2
V₂ = (5.00×423)/293
V₂ = 7.22 L

If you wanted to make 250 mL of a 0.01 M solution of CaCl, calculate how many moles of calcium chloride would be
needed. Your response must include both a correct numerical setup and the calculated result. [1]
Answer:
0.0025moles
Explanation:
Molarity of a solution (M) = number of moles (n) ÷ volume (V)
According to this question, to make 250 mL of a 0.01 M solution of CaCl, the following number of moles is needed:
Volume = 250mL = 250/1000 = 0.250Litres.
Using; molarity = n/V
0.01 = n/0.250
n = 0.0025
n = 2.5 × 10^-3 moles.

If you start with 13 mole H2O and 50 grams of O2 what is the percent yield of H202 if 100 grams of H202 is actually made?
Answer:
94.1 %
Explanation:
We firstly determine the equation:
2H₂O + O₂ → 2H₂O₂
2 moles of water react to 1 mol of oxygen in order to produce 2 moles of oxygen peroxide.
We convert the mass of oxygen to moles:50 g . 1mol /32g = 1.56 mol
Certainly oxygen is the limiting reactant.
2 moles of water react to 1 mol of oxygen.
13 moles of water may react to 13/2 = 6.5 moles. (And we only have 1.56)
As we determine the limiting reactant we continue to the products:
1 mol of O₂ can produce 2 moles of H₂O₂
Then 1.56 moles of O₂ will produce (1.56 . 2) = 3.125 moles
We convert the moles to mass: 3.125 mol . 34 g/mol= 106.25 g
That's the 100% yield or it can be called theoretical yield.
Percent yield = (Yield produced / Theoretical yield) . 100
(100g / 106.25 g) . 100 = 94.1 %
The mass of this atom is:
u. 3 mass units
b. 4 mass units
c. 6 mass units
d. 7 mass units
e. 11 mass units

For the reaction So3 + H2O -> H2SO4, how many grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid
Answer:
320 grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid.
Explanation:
The balanced reaction is:
SO₃ + H₂O → H₂SO₄
By reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
SO₃: 1 moleH₂O: 1 moleH₂SO₄: 1 moleBeing the molar mass of each compound:
SO₃: 80 g/moleH₂O: 18 g/moleH₂SO₄: 98 g/moleBy reaction stoichiometry, the following mass quantities of each compound participate in the reaction:
SO₃: 1 mole* 80 g/mole= 80 gramsH₂O: 1 mole* 18 g/mole= 18 gramsH₂SO₄: 1 mole* 98 g/mole= 98 gramsThen you can apply the following rule of three: if 1 mole of sulfuric acid is produced by the reaction of 80 grams of sulfur trioxide, 4 moles of sulfuric acid is produced from how much mass of sulfur trioxide?
[tex]mass of sulfur trioxide= \frac{4 moles of sulfuric acid* 80 grams of sulfur trioxide}{1 mole of sulfuric acid }[/tex]
mass of sulfur trioxide= 320 grams
320 grams of sulfur trioxide are required to produce 4.00 mol of sulfuric acid.
The mass of the required compound is 320 grams
Chemical reactionsGiven the chemical equation expressed as:
[tex]SO_3 + H_2O \rightarrow H_2SO_4[/tex]
According to stochiometry, 1 mole of SO3 produces 1 mole of H2SO4, hence the moles of SO3 will also be 4.00moles
Determine the mass of SO3
Mass = mole * molar mass
Mass = 4.0 * [32+3(16)]
Mass = 4.0 * 80
Mass = 320 grams
The mass of the required compound is 320 grams
