a student collected the _____ data to determine the specific heat of a metal sample.50.0 g of metal were transferred from boiling water into a calorimeter containing 100 g of h2o at temperature of the water rose to 23.5oc.calculate the specific heat of the metal. enter your answer with 3 significant figures.
Answers
The specific heat of the metal is approximately equal to 3.77 J/g°C.
To calculate the specific heat of the metal, we can use the equation:
q = m * c * ΔT
where:
q is the heat transferred,
m is the mass of the substance (in this case, water),
c is the specific heat capacity of the substance (in this case, water),
ΔT is the change in temperature.
Given the data:
Mass of the metal (m₁) = 50.0 g
Mass of water (m₂) = 100 g
Temperature change of water (ΔT) = 23.5°C
Assuming there is no heat loss to the surroundings, the heat gained by the water is equal to the heat lost by the metal. Therefore, we can write:
m₁ * c₁ * ΔT = m₂ * c₂ * ΔT
Rearranging the equation to solve for the specific heat of the metal (c₁), we have:
c₁ = (m₂ * c₂ * ΔT) / (m₁ * ΔT)
Substituting the given values, we get:
c₁ = (100 g * 4.18 J/g°C * 23.5°C) / (50.0 g * 23.5°C)
Evaluating the expression, the metal's specific heat is about equal to3.77 J/g°C.

how much heat is required to raise the temperature of a 10.35g sample of carbon tetrachloride from 32.1°c to 56.4°c? the specific heat of carbon tetrachloride is 0.85651j/g°c.
Answers
To raise the temperature of a 10.35g sample of carbon tetrachloride from 32.1°c to 56.4°c, 222.92J heat is required.
Heat is a form of energy and it is associated with the motion of particles. The amount of heat required to change the temperature of a substance depends on its mass, the specific heat capacity of the substance and the change in temperature.
The mass of carbon tetrachloride is given as 10.35g. The specific heat capacity of carbon tetrachloride is given as 0.85651 J/g°C and the change in temperature is given as 24.3°C. Putting these values into the formula: q = m × C × ΔTq = 10.35 g × 0.85651 J/g°C × 24.3°Cq = 222.92 J. Therefore, 222.92 Joules of heat are required to raise the temperature of a 10.35g sample of carbon tetrachloride from 32.1°c to 56.4°c.

Answers
1- ΔH2 = -ΔH1 (The enthalpy change for the reverse reaction is the negative of the enthalpy change for the forward reaction.)
2- ΔH3 = 3ΔH1 (The enthalpy change for the reaction involving the formation of 6 moles of Al2O3 is three times the enthalpy change for the formation of 2 moles of Al2O3.)
3- ΔH4 = 0.5ΔH1 (The enthalpy change for the reaction involving the formation of one mole of Al2O3 is half the enthalpy change for the formation of 2 moles of Al2O3.)
To express the enthalpy of a reaction in terms of another reaction, we can use the concept of Hess's law. Hess's law states that the overall enthalpy change of a reaction is independent of the pathway taken and depends only on the initial and final states of the reaction.
Expressing ΔH2 in terms of ΔH1:
The reaction (ΔH2) is the reverse of the formation of aluminium oxide from aluminium and oxygen (ΔH1), so the enthalpy change for the reverse reaction will have the opposite sign. Therefore, we have:
ΔH2 = -ΔH1
Expressing ΔH3 in terms of ΔH1:
The reaction (ΔH3) involves the formation of 6 moles of Al2O3, whereas the formation of Al2O3 in ΔH1 involves the formation of 2 moles of Al2O3. Therefore, the enthalpy change for ΔH3 will be three times that of ΔH1. Hence:
ΔH3 = 3ΔH1
Expressing ΔH4 in terms of ΔH1:
The reaction (ΔH4) involves the formation of one mole of Al2O3, whereas the formation of Al2O3 in ΔH1 involves the formation of 2 moles of Al2O3. Therefore, the enthalpy change for ΔH4 will be half that of ΔH1. Hence:
ΔH4 = 0.5ΔH1

Answers
Oxygen and water vapor are two of the most abundant gases in Earth’s atmosphere.
What is the water vapor's partial pressure?They are stored together, and the partial pressure of the oxygen can be calculated by subtracting the partial pressure of the water vapor from the total pressure.In this case, the partial pressure of the oxygen is 0.89 atm and the total pressure is 1.53 atm. Thus, the partial pressure of the water vapor is 0.64 atm.Mole fraction can be calculated from the partial pressure of each component of a gas mixture.The mole fraction of H₂ in the mixture is equal to 0.41 atm divided by the total pressure, which is 1.30 atm (0.41 atm + 0.89 atm). This works out to be 0.315.The mole fraction of He in the mixture is equal to 0.89 atm divided by the total pressure, which is 1.30 atm. This works out to be 0.685.

is the final temperature of the iron in kelvins? The specific heat of iron
is 0.449 J(g•K).
Answers
Answer:
569K
Explanation:
Q = 3.5kJ = 3500J
mass = 28.2g
∅1 = 20°C = 20 + 273 = 293K
∅2 = x
c = 0.449
Q = mc∆∅
3500 = 28.2×0.449×∆∅
3500 = 12.6618×∆∅
∆∅ = 3500/12.6618
∆∅ = 276.4220
∅2 - ∅1 = 276.4220
∅2 = 276.4220 + ∅1
∅2 = 276.4220 + 293
∅2 = 569.4220K
∅2 = 569K
When the temperature is increased, there is the increase in thermal energy of the system. The final temperature of the iron in kelvins is 570 K.
What is energy?The energy is the ability to do work.
Given is the energy Q = 3.5 kJ = 3500 J, mass of sample m = 28.2 g, specific heat of iron Cp = 0.449 J(g•K).
The initial temperature in kelvins is T1 = 20°C = 20 + 273 = 293K
The heat is related to the temperature difference as
Q = m c ∆T
Substitute the values into the expression,
3500 = 28.2 × 0.449 × ∆T
3500 = 12.6618 × (T2 -T1)
T2 - T1 = 276.4220
T2 = 276.4220 K +293 K
T2 = 569.4220K
The temperature of the iron is approximately 570 K.

carbonic acid, (oh)2c=o, pka = 3.57 at 37o c, is the basis of the blood's buffer system. what is the percent dissociation of carbonic acid in the stomach at ph = 3.00? the issociation i
Answers
The percent dissociation of carbonic acid in the stomach at pH 3.00 is approximately 39.2%.
To find the percent dissociation of carbonic acid in the stomach at pH 3.00, we need to calculate the ratio of the concentration of dissociated carbonic acid ([HCO3-]) to the initial concentration of carbonic acid ([H2CO3]). The percent dissociation can then be calculated by multiplying the ratio by 100.
Carbonic acid (H2CO3) dissociates into bicarbonate ions (HCO3-) and hydrogen ions (H+):
H2CO3 ⇌ HCO3- + H+
Given that the pKa of carbonic acid is 3.57, we can use the Henderson-Hasselbalch equation to calculate the ratio:
pH = pKa + log([HCO3-]/[H2CO3])
Rearranging the equation, we have:
[HCO3-]/[H2CO3] = 10^(pH - pKa)
Substituting the values, we get:
[HCO3-]/[H2CO3] = 10^(3.00 - 3.57) = 10^(-0.57) ≈ 0.392
The percent dissociation is then:
Percent dissociation = ([HCO3-]/[H2CO3]) * 100 = 0.392 * 100 ≈ 39.2%

What is the pressure of 1.45 moles of an ideal gas in a 3.23-liter container at 95 oC?
Answers
Therefore, the pressure of 1.45 moles of an ideal gas in a 3.23-liter container at 95°C is 6.84 atm.
What is pressure?The force exerted per unit area is measured as pressure. It is a physical quantity that describes the intensity of a force applied to a surface. It is defined as the amount of force applied to an item or material divided by the area across which the force is exerted. Pressure is measured in several units, including pascals (Pa), pounds per square inch (psi), atmospheres (atm), and torr. In ordinary life, the most common measure of pressure is probably psi or atm, although in scientific situations, the SI unit pascal is frequently employed. Pressure is a fundamental concept in many branches of science and engineering.
Here,
To solve this problem, we can use the ideal gas law, which relates the pressure (P), volume (V), number of moles (n), and temperature (T) of an ideal gas:
PV = nRT
where R is the gas constant.
We can rearrange the formula to solve for pressure:
P = nRT/V
We are given the number of moles of gas (n = 1.45 mol), the volume of the container (V = 3.23 L), and the temperature (T = 95°C + 273.15 = 368.15 K). The gas constant R is 0.08206 L⋅atm/(mol⋅K).
Substituting the values into the formula, we get:
P = (1.45 mol) * (0.08206 L⋅atm/(mol⋅K)) * (368.15 K) / (3.23 L)
P = 6.84 atm
