true or false: the molar enthalpy of sublimation of a given substance can be determined if its enthalpies of fusion and vaporization are known.
Answers
The given statement "The molar enthalpy of sublimation of a given substance can be determined if its enthalpies of fusion and vaporization are known" is true.
The molar enthalpy of sublimation of a substance can be determined if its enthalpies of fusion (melting) and vaporization (boiling) are known. The enthalpy of sublimation refers to the energy required to change a substance from the solid phase directly to the gaseous phase, bypassing the liquid phase.
The enthalpy change during sublimation can be calculated by considering the enthalpies of fusion and vaporization. When a substance undergoes sublimation, it first requires energy to melt from the solid phase to the liquid phase (enthalpy of fusion) and then additional energy to vaporize from the liquid phase to the gaseous phase (enthalpy of vaporization). The sum of these two enthalpies represents the overall energy change during sublimation.
Therefore, by adding the enthalpy of fusion and the enthalpy of vaporization, one can determine the molar enthalpy of sublimation for a given substance.

d. are made up of at least two substances
Answers
Answer:
D
-----------------------------------------------------------------
The definition of colloids is very disputed on whether or not it is homo/heterogenous. I wouldn't go with this answer, but its based on what you learned it was. At a microscopic level its hetero but at a macroscopic its homo.
They do have somewhat large dispersed particles but this better describes suspensions
They don't easily settle out.
And in order to be a mixture, they are made up of at least two substances
D is likely the best answer out of the bunch.
Colloids are made up of at least two substances. Therefore, option d is correct.
What are colloids?A colloid can be described as a mixture in which one substance consisting of dispersed insoluble particles is throughout another substance. The particles should be dispersed in a liquid. The term colloidal suspension can be referred to unambiguously as the overall mixture.
A colloid exhibits a dispersed phase and a continuous phase. The dispersed phase particles have a diameter of about 1 nm to 1 μm. Some colloids are translucent due to the Tyndall effect and other colloids can be opaque or have a slight color.
Hydrocolloids can be described as certain chemicals that are colloidally dispersible in water. Therefore becoming very "soluble" they can change the rheology by raising the viscosity.
A colloid possesses a dispersed phase and a continuous phase. A solute in a solution is individual molecules, whereas colloidal particles can be bigger.

Which of the following statements correctly describe wave-particle duality? Select all that apply.
All matter exhibits wavelike motion.
Matter and energy are different forms of the same entity.
Energy and mass can be interconverted.
Answers
Wave-particle duality is a fundamental concept in quantum mechanics that describes the dual nature of particles and waves. The following statements correctly describe wave-particle duality:
1. All matter exhibits wavelike motion: This statement reflects the wave nature of particles. Even though particles have localized positions, they also exhibit wave-like properties, such as diffraction and interference.
2. Matter and energy are different forms of the same entity: According to Einstein's theory of relativity (E=mc²), energy and mass are interconnected. This concept suggests that matter can be viewed as a form of energy.
3. Energy and mass can be interconverted: This statement is a direct implication of Einstein's famous equation. It means that mass can be converted into energy and vice versa. This phenomenon is observed in nuclear reactions and particle interactions.
Wave-particle duality highlights the wave-like and particle-like behaviors exhibited by particles at the microscopic level. It revolutionized our understanding of the fundamental nature of matter and laid the foundation for quantum mechanics.

The example of a reaction to which Markovnikov's rule applies is: CH₂=CH-CH₂-CH₃ + HBr → CH₂Br-CH₂-CH₂-CH₃
In this reaction, the hydrogen atom from HBr adds to the carbon atom with the fewer alkyl substituents (less substituted carbon), while the bromine atom adds to the carbon atom with more alkyl substituents (more substituted carbon). This follows Markovnikov's rule, which states that in the addition of a protic acid (such as HBr) to an asymmetrically substituted alkene, the hydrogen atom adds to the less substituted carbon and the other atom adds to the more substituted carbon.

A student heats a sample of Copper (II) sulfate in a crucible and records the data shown in the table. What is the complete formula and name for the compound before heating?
Mass of empty crucible 128.10 g
Mass of crucible + sample before heating 152.00 g
Mass of crucible + sample after heating 147.60 g
Answers
Explanation:
Copper (II) sulfate is usually present as a hydrous state, which is of the form CuSO4 * nH2O, where n is a whole number.
Mass of sample (CuSO4 * nH2O)
= 152.00g - 128.10g = 23.90g.
Mass of water loss during heating
= 152.00g - 147.60g = 4.40g.
Molar mass of H2O = 18g/mol
Moles of H2O in sample
= 4.40g / (18g/mol) = 0.244mol.
Mass of anhydrous sample (CuSO4)
= 23.90g - 4.40g = 19.50g
Molar mass of CuSO4 = 159.61g/mol
Moles of CuSO4 in sample
= 19.50g / (159.61g/mol) = 0.122mol.
Since mole ratio of CuSO4 to H2O
= 0.122mol : 0.244mol = 1:2, n = 2.
Hence we have CuSO4 * 2H2O.
Answer:
Copper(II) Sulphate (CuSO4.7H2O) is generally present in a hydrated form.
Mass of the CuSO4.7H2O sample before heating
(152.00-128.10)g = 23.90 grams
Mass of the water loss due to heating
(152.00-147.60)g = 4.40 grams

Memorandum of physics grade 10 term 1 formal experiment of heating and cooling curve of water
The Heating and Cooling curve of water is a popular physics experiment that visualizes the changes in temperature and state of water during heating and cooling processes. This experiment helps students understand concepts related to energy transfer during phase changes.
Explanation:The Heating and Cooling curve of water represents a formal physics experiment which involves observing and plotting temperature changes as water heats up and cools down. The curve normally consists of five distinct stages of changes in temperature and state.
When conducting this experiment, you must carefully monitor the temperature at which the water boils, condenses, and freezes. By plotting these temperatures against time, you will get an insight into the energy transfer during heating and cooling processes. The 'plateaus' on the graph represent a change in state.
During 'plateaus', temperature remains constant even though heat is being added or removed. This is because the energy goes into changing the state of the substance, rather than increasing its temperature.

2 moles of NO, was placed in an empty I dm' bottle and allowed to reach equilibrium according to the equation:
At equilibrium, 1.2 moles of N,O, dissociated. Calculate the value of the equilibrium constant for the reaction at that
temperature.
Answers
2NO(g) ⇌ N2(g) + O2(g)
According to the problem statement, 2 moles of NO were placed in a 1 dm^3 bottle and allowed to reach equilibrium, and at equilibrium, 1.2 moles of NO had dissociated. This means that the initial concentration of NO was:
[NO]initial = 2 mol / 1 dm^3 = 2 M
And the concentration of NO at equilibrium is:
[NO]equilibrium = (2 - 1.2) mol / 1 dm^3 = 0.8 M
Since the stoichiometry of the balanced equation is 2:1:1 for NO, N2, and O2, respectively, the equilibrium concentrations of N2 and O2 will also be 0.6 M.
The equilibrium constant (Kc) can be calculated using the equilibrium concentrations of the reactants and products, raised to the power of their stoichiometric coefficients. Therefore:
Kc = ([N2][O2]) / ([NO]^2)
Substituting the equilibrium concentrations into the equation, we get:
Kc = (0.6 M x 0.6 M) / (0.8 M x 0.8 M)
Kc = 0.5625
Therefore, the value of the equilibrium constant for the reaction at that temperature is 0.5625. Note that the units of Kc depend on the stoichiometry of the balanced equation. Since the stoichiometric coefficients are all 1, the units of Kc in this case are M^-1
