An alkyne with the molecular formula C6H10 was reduced with H2 and Lindlar's catalyst. Ozonolysis of the resulting alkene afforded formaldehyde and an unbranched aldehyde. What is the IUPAC name of the alkyne that was reduced?
Given that the alkyne has a formula as C₆H₁₀, the IUPAC name of the alkyne is hexyne
What is an alkyne?Alkynes are unsaturated hydcarbons with the general formula of CₙH₂ₙ₋₂. They contains triple bonds (C≡C) in the carbon chains. The simplest member of this family is ethyne (C₂H₂)
The first nine members of the Alkynes sre:
Ethyne, C₂H₂Propyne, C₃H₄ Butyne, C₄H₆ Pentyne, C₅H₈Hexyne, C₆H₁₀Heptyne, C₇H₁₂Octyne, C₈H₁₄Nonyne, C₉H₁₆Decyne, C₁₀H₁₈Considering the question given above, the formula of the alkyne is C₆H₁₀.
Therefore, the name of the alkyne is hexyne

calculate the pressure in atmospheres of 1.92 moles of helium gas in a 10.0L container at 25C
The pressure in atmospheres of the given mole and volume of helium gas is 4.7atm.
Given the data in the question;
Amount of helium; [tex]n = 1.92mol[/tex]Volume of the gas; [tex]V = 10.0L[/tex]Temperature; [tex]T = 25^0C = 298.15K[/tex]Pressure in atmosphere; [tex]P = \ ?[/tex]
Ideal Gas LawThe Ideal gas law emphasizes on the behavior of a hypothetical ideal gas. It states that pressure P multiply by volume V is equal to moles times temperature and the universal gas constant.
It is expressed;
[tex]PV = nRT[/tex]
Where P is pressure, V is volume, n is the amount of substance, T is temperature and R is the ideal gas constant.( [tex]R = 0.08206Latm/molK[/tex] ).
To determine the pressure in atmosphere, we substitute our values into the expression above.
[tex]PV = nRT\\\\P = \frac{nRT}{V} \\\\P = \frac{1.92mol\ *\ 0.08206Latm/molK\ *\ 298.15K}{10.0L} \\\\P = \frac{46.975Latm}{10.0L}\\\\P = 4.7atm[/tex]
Therefore, the pressure in atmospheres of the given mole and volume of helium gas is 4.7atm.

A molecule that is either cycloheptane or cycloheptene is treated with bromine and the sample immediately absorbs the red bromine color—which compound is present?
The compound that is most likely present when treated with bromine and the sample absorbs the red bromine color is ; Cycloheptene
What is cyclohepteneCycloheptene is an unsaturated colorless oily liquid which is insoluble in water it absorbs Bromine when used in performing unsaturation test due it unsaturated nature.
The red bromine color will be absorbed when used to treat Cycloheptene but will not be absorbed when used to treat cycloheptane due to its saturated nature.
Hence we can conclude that the compound that is present is Cycloheptene.

A. N2O B. CO C. HCL D. Na2O
Answer:
D. Na2O
Because we already know that sodium oxide is a binary ionic compound because it contains one metal cation and one non-metal anion.
Answer:
D. Na2O
Explanation:
Sodium oxide (Na2O) is an ionic compound. Its constituent atoms are, respectively, a metal and a non-metal.
Sodium (Na), as a metal, will attempt to lose electrons to reach an octet state. Oxygen (O2), as a non-metal, will attempt to gain electrons to reach an octet state.

6. How many moles of water would require 92.048 kJ of heat to raise its temperature from 34.0 °C to 100.0 °C? (3 marks)
Taking into account the definition of calorimetry, 0.0185 moles of water are required.
CalorimetryCalorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).
So, the equation that allows to calculate heat exchanges is:
Q = c× m× ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
Mass of water requiredIn this case, you know:
Heat= 92.048 kJMass of water = ?Initial temperature of water= 34 ºCFinal temperature of water= 100 ºCSpecific heat of water = 4.186 [tex]\frac{J}{gC}[/tex]Replacing in the expression to calculate heat exchanges:
92.048 kJ = 4.186 [tex]\frac{J}{gC}[/tex]× m× (100 °C -34 °C)
92.048 kJ = 4.186 [tex]\frac{J}{gC}[/tex]× m× 66 °C
m= 92.048 kJ ÷ (4.186 [tex]\frac{J}{gC}[/tex]× 66 °C)
m= 0.333 grams
Moles of water requiredBeing the molar mass of water 18 [tex]\frac{g}{mole}[/tex], that is, the amount of mass that a substance contains in one mole, the moles of water required can be calculated as:
[tex]amount of moles=0.333 gramsx\frac{1 mole}{18 grams}[/tex]
amount of moles= 0.0185 moles
Finally, 0.0185 moles of water are required.
