How many grams of CaH2 are needed to generate 53.5 L of H2 gas if the pressure of H2 is 1 atm at 194 C.
The average January temperature in New Orleans is 56 F. The average July temperature is 83 F. Consider a house in the city that exchanges heat with the outside in accordance with the relation dq/dt = A(To - Ti).
The complex ion [Co(CN)3]^3- absorbs a photon of wavelength 2.90×10^2 nm. What is the splitting energy of this complex in kJ/mol?
Nitrogen dioxide and water react to produce nitric acid HNO3 and nitrogen monoxide.
14.0 moles of gas are in a 6.00 L tank at 22.6 C. Calculate the difference in pressure between methane and an ideal gas under these conditions.
calculate how many moles of KIO3 are needed to make 50 ml of 0.20 M solution?
A solution is prepared by mixing 87.0 mL of 5.00 M HCl and 36.0 mL of 8.00 M HNO3. Water is then added until the final volume is 1.00 L. Calculate [H+ ], [OH - ], and the pH for this solution.
These two substances reach thermal equilibrium at a temperature of 64.2 degree celsius. If the specific heat capacity of substance "B" is 1.17 J / g-C, what is the specific heat of substance "A". (assume no heat is lost to the surroundings)
In a reaction, 82.00 g of sodium reacts with 74.00 g of ferric oxide to form sodium oxide and iron metal. Calculate the mass of solid iron produced
An unknown gas has been determined to have the empirical formula CH2. At 27°C and 0.966 atm, the gas has a density of 1.65 g/L. What is the molecular formula of this gas
Suggest to her a visual functional test that she can use to detect the presence of an alkene. Explain why it is specific for alkenes in this situation.
Calorimetry is a method used to measure enthalpy, or heat, changes that occur during chemical processes. Two common calorimeters are constant-pressure calorimeters and constant-volume (or "bomb") calorimeters
