can you Compare the experimental value obtained for the specific heat capacity with the theoretical value?
Yes.
When what flows into a system it's value is positive when heat flows out of the system it's value is negative?
heat. apex.
Why the experimental value of specific heat capacity is higher than the standars value?
Experimental errors would cause the experimental value of specific heat capacity to be higher than the standard value.
A well insulated house should have insulation with an r-value of at least r-19 in the walls and an r-value of r-30 to r-44 in the ceilings why is higher r-value needed in the ceilings?
Heat rises so you want to keep heat in the home in winter and to keep heat out in the summer.
Why does specific heat has the same numerical value in metric and british systems?
Specific heat is dimensionless, and dimensionless units have the same value in any system. Specific heat is the ratio between two densities - that of the substance considered, and that of water. The ratio of two quantities of the same dimension will naturally be a dimensionless number.
can you Compare the experimental value obtained for the specific heat capacity with the theoretical value?
Yes.
What is the standard enthalpy of hydrogenation of 1-butene?
The standard enthalpy of hydrogenation of 1-butene is -30.1 kJ/mol. This value represents the amount of heat released when one mole of 1-butene is completely hydrogenated to form butane.
Is benzene a best conductor of heat?
No, benzene is a poor conductor of heat as it is a nonpolar molecule. This means that it does not have free-moving electrons that can efficiently transfer heat energy.
What is the specific heat of benzene if 3450J of heat is added to 150.0 g sample of benzene and its temperature increases from 22.5 degrees celsius to 35.8 degrees celsius?
The specific heat of benzene is 1.75 J/g°C. You can use the formula q = mcΔT, where q is the heat added, m is the mass of benzene, c is the specific heat, and ΔT is the change in temperature. Plug in the values and solve for c.
How much energy must be removed from a 125 g sample of benzene at K to liquefy the sample and lower the temp to 335.0 K?
To find the energy required to lower the temperature of benzene from K to 335.0 K and liquefy it, you need to calculate the heat energy using the specific heat capacity of benzene and the heat of fusion of benzene. This will involve calculating the energy required to cool the benzene from K to its freezing point and then the energy required to change its state at the freezing point.
What is the heat reaction for 3 C2H2g plus C6H6l?
The reaction you provided is not balanced. However, if you mean the combustion reaction of 3 moles of acetylene (C2H2) with 1 mole of benzene (C6H6), the balanced equation would be 3C2H2(g) + 9O2(g) -> 6CO2(g) + 2H2O(g) with a heat release of -6254 kJ.
A theoretical condition where no heat is present is?
Cold fusion
What is heat capacity of H2SiO3 relation of temperature?
The heat capacity of H2SiO3 (silicic acid) typically increases with temperature as more energy is required to raise the temperature of the substance. The specific heat capacity value at any given temperature can be obtained from experimental measurements or theoretical calculations.
What is the function of the zinc dust in organic?
Zinc dust is sometimes used as a reagent in organic chemistry reactions, particularly in reductions. It can provide electrons to reduce functional groups such as alkyl halides or carbonyl compounds to achieve specific synthetic transformations.
Why is the enthalpy of formation of benzene is endothermic?
The enthalpy of formation of benzene is endothermic because it requires an input of energy to form from its elements in their standard states. The formation of benzene involves breaking the bonds in the elements and rearranging them to form the benzene structure, which results in an overall absorption of heat energy.
What is the term for the theoretical temperature characterzation by the complete absence of heat?
Absolute zero is the theoretical temperature at which all motion stops and heat energy is completely absent. This temperature is represented as 0 Kelvin or -273.15 degrees Celsius.
What is the resonance energy of cyclooctatetraene?
Cyclooctatetraene does not exhibit resonance energy because it is not a stable molecule in a planar conformation. Due to its non-planar geometry, the pi electrons are delocalized in a non-resonant manner, leading to a lack of resonance stabilization.
