The molecules CH4 and CH3Cl both have tetrahedral shapes. Why is CH4 nonpolar whereas CH3Cl is polar
The molar heat of combustion of methanol (molar mass = 32.0g/mol) is -757kJ/mol. If 2.00 g of methanol is placed in a bomb calorimeter with a heat capacity of 6.50 kJ/degree C what is the temperature rise when the sample is combusted?
By comparison, what would it cost to heat the home using a ground source heating system with an electrically powered heat pump that has a COP of 5.0?
Why does a permanent magnet attract pieces of ferromagnetic materials?
Consider the following species with tetrahedral electron-pair geometries and select the species with the smallest predicted bond angles.
Using standard reduction potentials, calculate the equilibrium constants for the following reactions.
Question- Predict the main/most stable di-nitration product of benzil and draw a mechanims for how the product formed. 1) Would you expect this di-nitration product to above or below the desired product spot (benzil) on a TLC plate
1. chloride ions + silver nitrate 2. hydrogen carbonate + nitric acid
How can you visually demonstrate that a substance is insoluble or just slightly soluble. Some solid remains in both cases.
Use enthalpy of formation data to calculate the number of moles of CO2(g) produced per megajoule of heat released from the combustion of each fuel under standard conditions
The boiling point of methanol is 65.0C as well as the standard enthalpy of formation of methanol vapor is -201.2 kj/mol. Explain how would compute their vapor pressure of methanol (in mmhg) at 25C
